welcome to the compress heat exchanger
00:00:03.020 00:00:03.030 demonstration today I'm going to go over
00:00:05.269 00:00:05.279 some of the features that are available
00:00:06.260 00:00:06.270 to you and compress and how we design
00:00:08.030 00:00:08.040 heat exchangers so let's get started
00:00:15.910 00:00:15.920 here's a typical heat exchange that I
00:00:18.260 00:00:18.270 had modeled and compress so this is our
00:00:20.270 00:00:20.280 fixed exchanger we have a Belle's
00:00:22.550 00:00:22.560 expansion joint on it and we can take a
00:00:24.500 00:00:24.510 look inside this exchanger - so we click
00:00:26.750 00:00:26.760 on the show internals button you can see
00:00:28.880 00:00:28.890 we'll also represent the tube sheet in
00:00:30.350 00:00:30.360 the tube bundle for you and you can see
00:00:32.179 00:00:32.189 some baffles there but how do we go
00:00:34.400 00:00:34.410 about designing a seed exchanger with
00:00:37.940 00:00:37.950 the heat exchanger module and compress
00:00:39.710 00:00:39.720 we set up everything what we call a
00:00:41.270 00:00:41.280 wizard and what this does is it's a a
00:00:43.460 00:00:43.470 large dialog that contains all of the
00:00:45.319 00:00:45.329 information for the heat exchanger
00:00:46.960 00:00:46.970 benefit of doing it like this is that
00:00:49.790 00:00:49.800 instead of having to model thing
00:00:50.870 00:00:50.880 component by component we can simply
00:00:52.640 00:00:52.650 just enter in all of the design data
00:00:54.620 00:00:54.630 let's say from a team aspect sheet or a
00:00:56.510 00:00:56.520 client spec sheet and we'll model the
00:00:58.280 00:00:58.290 heat exchanger for you so why don't we
00:01:00.170 00:01:00.180 go ahead and model this exchanger so
00:01:02.240 00:01:02.250 what I'm going to do is come up to the
00:01:03.470 00:01:03.480 file menu select new and we're going to
00:01:07.490 00:01:07.500 select heat exchanger
00:01:12.420 00:01:12.430 so this will open up our heat exchanger
00:01:13.980 00:01:13.990 dialog and then we can start filling out
00:01:16.800 00:01:16.810 the information so what we'll do in the
00:01:18.900 00:01:18.910 heat exchangers will first ask you for
00:01:21.020 00:01:21.030 general configuration and this is on our
00:01:23.370 00:01:23.380 general options page that's just see in
00:01:24.810 00:01:24.820 front of you so for example the exchange
00:01:27.120 00:01:27.130 your type well we'd like to design a
00:01:28.530 00:01:28.540 fixture stationery tube sheet we'd like
00:01:30.870 00:01:30.880 to do a YouTube or even a floating tube
00:01:32.820 00:01:32.830 sheet then we ask you for the
00:01:35.010 00:01:35.020 calculation method compressed can design
00:01:37.800 00:01:37.810 changes using the team rules the a/c new
00:01:40.260 00:01:40.270 rules or both then we have few other
00:01:43.500 00:01:43.510 options for the eights me such as our
00:01:45.150 00:01:45.160 shell bands president would you like to
00:01:46.620 00:01:46.630 use the operating temperatures things
00:01:48.270 00:01:48.280 like that for the team of rules we can
00:01:50.969 00:01:50.979 choose which addition you'd like to use
00:01:52.440 00:01:52.450 whether you'd like to use the 7th
00:01:53.820 00:01:53.830 addition the 8th edition or the ninth
00:01:55.620 00:01:55.630 edition and then the team a class and
00:01:57.500 00:01:57.510 then if there's going to be an expansion
00:01:59.609 00:01:59.619 joint present from here we ask you the
00:02:03.359 00:02:03.369 type of shell that we're going to be
00:02:04.560 00:02:04.570 designing so this is gonna be a one-pass
00:02:06.180 00:02:06.190 shell a two pass
00:02:07.620 00:02:07.630 split flow things like that now the
00:02:10.800 00:02:10.810 other item that we have on this dialogue
00:02:12.449 00:02:12.459 is our heat exchanger defaults what we
00:02:15.150 00:02:15.160 can do is set up defaults files so that
00:02:16.890 00:02:16.900 once we enter in our heat exchanger we
00:02:19.410 00:02:19.420 can save all these inputs and this is
00:02:21.240 00:02:21.250 very handy if you're doing or you're
00:02:23.220 00:02:23.230 building the same type of unit so for
00:02:26.160 00:02:26.170 example if your company specializes in
00:02:28.290 00:02:28.300 three different sizes of units well you
00:02:30.840 00:02:30.850 can save let's say the 60 inch unit the
00:02:33.120 00:02:33.130 90 inch unit and maybe the hundred
00:02:34.650 00:02:34.660 twenty inch unit so if a client calls
00:02:36.240 00:02:36.250 and says I need a sixty inch unit we can
00:02:38.370 00:02:38.380 load this defaults file in and we can
00:02:40.949 00:02:40.959 make any slight changes we may need to
00:02:42.509 00:02:42.519 so what would you do is just simply
00:02:44.430 00:02:44.440 select defaults file here and when you
00:02:48.000 00:02:48.010 save it you just simply go and look it
00:02:49.949 00:02:49.959 up like so so I'll loading the heat
00:02:52.110 00:02:52.120 exchanger demo click open and it'll get
00:02:55.920 00:02:55.930 loaded now you can also create a new
00:02:58.259 00:02:58.269 default file so this is a new exchanger
00:03:00.390 00:03:00.400 you can save all these inputs as you're
00:03:02.310 00:03:02.320 going along and then save them
00:03:03.600 00:03:03.610 afterwards as well ok so this page is
00:03:06.360 00:03:06.370 set right now and I've loaded in my heat
00:03:08.789 00:03:08.799 exchanger demo defaults so what I'm
00:03:10.770 00:03:10.780 going to do is click Next now the first
00:03:14.160 00:03:14.170 few pages for the heat exchanger
00:03:15.810 00:03:15.820 dialogue are going to be for the design
00:03:17.340 00:03:17.350 conditions we're going to look at the
00:03:18.630 00:03:18.640 tube side design conditions then we're
00:03:20.460 00:03:20.470 going to look at the shell side design
00:03:21.660 00:03:21.670 conditions the tube sheet design
00:03:23.430 00:03:23.440 conditions and then some bellows joint
00:03:25.680 00:03:25.690 can do
00:03:26.250 00:03:26.260 and liquid levels so for the tube side
00:03:30.720 00:03:30.730 design conditions we can set up multiple
00:03:33.500 00:03:33.510 conditions so for example I've got four
00:03:36.240 00:03:36.250 set up here I have the operating
00:03:39.440 00:03:39.450 condition the startup condition the
00:03:42.300 00:03:42.310 shutdown and the up set and these are
00:03:43.979 00:03:43.989 what I set up so you can name them
00:03:45.569 00:03:45.579 anything you want and then based on this
00:03:48.600 00:03:48.610 we just go through some very basic
00:03:50.270 00:03:50.280 inputs so for example the internal
00:03:53.130 00:03:53.140 design pressure the internal design
00:03:55.170 00:03:55.180 temperature the external design pressure
00:03:57.990 00:03:58.000 and then the operating pressure and we
00:04:00.210 00:04:00.220 would do this for each one of our
00:04:01.259 00:04:01.269 conditions then we're going to select
00:04:04.619 00:04:04.629 the materials for the tube side
00:04:06.089 00:04:06.099 components so for example we have the
00:04:08.819 00:04:08.829 tube right here we just look the
00:04:10.920 00:04:10.930 material from the pulldown list and you
00:04:12.599 00:04:12.609 select the tube that you'd like to use
00:04:15.289 00:04:15.299 from here we'll just need to know the
00:04:17.699 00:04:17.709 tube mean metal temperature for each of
00:04:19.740 00:04:19.750 the conditions if you'd like to see some
00:04:21.840 00:04:21.850 material properties you can click on the
00:04:24.300 00:04:24.310 show material properties button right
00:04:25.860 00:04:25.870 here and you can see we're compresses
00:04:27.779 00:04:27.789 pulling a lot of the information from
00:04:29.610 00:04:29.620 for example the thermal expansion
00:04:30.900 00:04:30.910 coefficients ores the yield stress
00:04:33.390 00:04:33.400 source things like that I'm just gonna
00:04:35.550 00:04:35.560 hide this and then we're gonna do the
00:04:37.830 00:04:37.840 same thing for the channel cylinder so
00:04:39.960 00:04:39.970 again from the pulldown menu we're just
00:04:41.610 00:04:41.620 going to select the material that we're
00:04:42.930 00:04:42.940 going to build the channel out of so
00:04:46.230 00:04:46.240 what I'm going to do is I'm going to
00:04:47.070 00:04:47.080 click Next and then we're going to do
00:04:49.800 00:04:49.810 the same thing for the shell side
00:04:51.290 00:04:51.300 conditions as well so for example we
00:04:53.820 00:04:53.830 have our operating startup shut down up
00:04:55.980 00:04:55.990 side condition we just need to enter in
00:04:58.020 00:04:58.030 the pressure and temperatures external
00:05:00.450 00:05:00.460 design pressure and the operating
00:05:02.010 00:05:02.020 pressure and then select the material
00:05:04.379 00:05:04.389 and the shell mean metal temperature so
00:05:08.400 00:05:08.410 again I'll click Next here then we come
00:05:11.070 00:05:11.080 to the tube sheets page now since we've
00:05:12.930 00:05:12.940 already set up the shell side and the
00:05:14.670 00:05:14.680 tube side design conditions we already
00:05:16.170 00:05:16.180 know what pressure and temperature is
00:05:17.279 00:05:17.289 acting on either side so really with the
00:05:19.320 00:05:19.330 tube sheet we just need to know the
00:05:21.120 00:05:21.130 material like so and then the mean metal
00:05:25.290 00:05:25.300 temperature as well so again from here
00:05:28.290 00:05:28.300 I'll just click Next
00:05:29.279 00:05:29.289 and because I have a bellows expansion
00:05:32.129 00:05:32.139 joint set up in this defaults file will
00:05:34.529 00:05:34.539 ask you for the design conditions for
00:05:36.000 00:05:36.010 this as well mainly we're going to ask
00:05:37.560 00:05:37.570 you for the material
00:05:39.439 00:05:39.449 alright I'll collect next then we can
00:05:42.869 00:05:42.879 specify a liquid level acting on our
00:05:44.609 00:05:44.619 heat exchanger why is this important
00:05:46.889 00:05:46.899 well compress will automatically account
00:05:49.199 00:05:49.209 for the static head that might be acting
00:05:50.789 00:05:50.799 on the tube sheet and this is part of
00:05:52.469 00:05:52.479 the code requirements we need to
00:05:53.639 00:05:53.649 consider all loadings acting on the tube
00:05:55.469 00:05:55.479 sheet so there is a liquid level we can
00:05:57.989 00:05:57.999 specify it here ok so so far we've set
00:06:02.369 00:06:02.379 up our design conditions
00:06:03.719 00:06:03.729 so now compresses everything that you
00:06:05.579 00:06:05.589 need to start selecting sizes ways so
00:06:07.619 00:06:07.629 the next few pages are going to be the
00:06:09.059 00:06:09.069 component portion of the heat exchanger
00:06:11.489 00:06:11.499 so I'll click Next and we're going to
00:06:14.819 00:06:14.829 start with the tube geometry Michelle
00:06:16.589 00:06:16.599 and then any baffles so the first thing
00:06:19.679 00:06:19.689 we're going to do is we're going to look
00:06:20.699 00:06:20.709 at the tube geometry so what we'll need
00:06:22.799 00:06:22.809 to know is the length between the outer
00:06:24.569 00:06:24.579 tube sheets so essentially the overall
00:06:26.069 00:06:26.079 length of your tube bundle so we'll just
00:06:27.839 00:06:27.849 leave it at 120 inches and then we need
00:06:30.389 00:06:30.399 to select the tube diameter and the wall
00:06:32.279 00:06:32.289 thickness now you can type in this
00:06:33.719 00:06:33.729 information if you'd like or we can
00:06:35.519 00:06:35.529 select a tube from here and we can look
00:06:37.919 00:06:37.929 up you know the specific size that we'd
00:06:39.839 00:06:39.849 like to use and click OK now one thing
00:06:43.529 00:06:43.539 you may notice here is that beside the
00:06:45.449 00:06:45.459 wall thickness input there's a block
00:06:47.189 00:06:47.199 text well what does this mean this is a
00:06:49.589 00:06:49.599 calculated minimum so as we're designing
00:06:52.019 00:06:52.029 our heat exchanger we're constantly
00:06:53.489 00:06:53.499 running calculations or in the
00:06:54.989 00:06:54.999 background so based on all the inputs we
00:06:57.119 00:06:57.129 have so far this is the minimum tube
00:06:59.279 00:06:59.289 wall thickness that we need to account
00:07:00.719 00:07:00.729 for and keep in mind there's also going
00:07:02.699 00:07:02.709 to be a tube mil tolerance applied to
00:07:04.889 00:07:04.899 this as well all right from here we just
00:07:08.519 00:07:08.529 need to know the tube expansion depth
00:07:10.079 00:07:10.089 ratio type that in and then we can move
00:07:12.629 00:07:12.639 on to the next component which in our
00:07:14.399 00:07:14.409 case is going to be the shell so again
00:07:16.949 00:07:16.959 just type in the inner diameter you have
00:07:18.809 00:07:18.819 and the thickness will tell you what the
00:07:21.209 00:07:21.219 minimum needs to be if there's any
00:07:23.159 00:07:23.169 corrosion on the inside or outside of
00:07:24.719 00:07:24.729 the show and then the MDM T now this MD
00:07:28.049 00:07:28.059 MT input is a target MDM T so this is
00:07:30.329 00:07:30.339 what we're trying to design to more than
00:07:33.569 00:07:33.579 likely this might actually be able to go
00:07:34.709 00:07:34.719 a lot lower than 0 degrees but if it's
00:07:36.959 00:07:36.969 not let's say it's only good to 10
00:07:38.609 00:07:38.619 degrees we're gonna warn you in the
00:07:40.319 00:07:40.329 report all right and the last thing
00:07:44.729 00:07:44.739 we're gonna do here is we're going to
00:07:45.779 00:07:45.789 specify baffles now you can do this in
00:07:48.179 00:07:48.189 two ways if you know where the baffles
00:07:49.679 00:07:49.689 are laid out now we can enter in them
00:07:51.449 00:07:51.459 for me
00:07:52.209 00:07:52.219 but if you don't what we what you could
00:07:54.129 00:07:54.139 do is just take the battlezone for the
00:07:55.510 00:07:55.520 time being get the rest of the heat
00:07:57.760 00:07:57.770 exchanger set and then come back in and
00:07:59.080 00:07:59.090 add them but again and there's our
00:08:01.089 00:08:01.099 baffles present we just activate this
00:08:03.399 00:08:03.409 option you can have compressed
00:08:05.260 00:08:05.270 automatically place the baffles for you
00:08:07.600 00:08:07.610 or you can turn this off and you can
00:08:08.920 00:08:08.930 manually space them where you'd like
00:08:11.679 00:08:11.689 them on the heat exchanger okay so the
00:08:14.649 00:08:14.659 tubes and shell page is done right now
00:08:16.209 00:08:16.219 so what I'll do is I'll click Next and
00:08:18.399 00:08:18.409 then we come to the channel page so this
00:08:21.040 00:08:21.050 is where we're going to look at the
00:08:21.879 00:08:21.889 front in the rear channel so up at the
00:08:24.399 00:08:24.409 top here we have to decide well what
00:08:26.080 00:08:26.090 type of channel are we going to use we
00:08:28.749 00:08:28.759 can do a channel type which would
00:08:30.869 00:08:30.879 encompass a bowl to cover or welded
00:08:33.490 00:08:33.500 cover if you decide to go with a bowl to
00:08:35.500 00:08:35.510 cover we can design the flanges using
00:08:37.719 00:08:37.729 the appendix 2 rules or we can look up a
00:08:39.730 00:08:39.740 B 16 v flange for you we can also do a
00:08:42.730 00:08:42.740 reducer and then a bond and type now the
00:08:45.610 00:08:45.620 front channel is currently set up with a
00:08:46.990 00:08:47.000 bono type and I have an ellipsoidal head
00:08:48.939 00:08:48.949 being used but I can also use an F and D
00:08:51.280 00:08:51.290 head or a hemispherical head from here
00:08:55.000 00:08:55.010 we just need to know the geometry of the
00:08:56.769 00:08:56.779 head itself so first thing is the
00:08:59.710 00:08:59.720 material and then the diameter the
00:09:02.259 00:09:02.269 minimum thickness straight flange like
00:09:04.480 00:09:04.490 things like that and then again we'll do
00:09:07.150 00:09:07.160 the same thing for the channel cylinder
00:09:08.699 00:09:08.709 once you get this set we'll switch over
00:09:11.259 00:09:11.269 to the rear now if you have bonnets on
00:09:13.150 00:09:13.160 both sides you could actually copy the
00:09:14.949 00:09:14.959 front end property so you don't need to
00:09:16.300 00:09:16.310 type the information in again but I
00:09:18.130 00:09:18.140 chose to set this up as a bowl to cover
00:09:19.930 00:09:19.940 and I've got an appendix to flange on
00:09:21.699 00:09:21.709 this so once we get this all set what we
00:09:25.389 00:09:25.399 can do is click Next and then we come to
00:09:29.199 00:09:29.209 our expansion joint page the expansion
00:09:31.329 00:09:31.339 joint page will just need to know
00:09:32.470 00:09:32.480 geometry the expansion joint and then we
00:09:35.380 00:09:35.390 can just type this information in the
00:09:36.970 00:09:36.980 inputs here so again I'll click Next and
00:09:42.600 00:09:42.610 then we come to the tube sheets page so
00:09:46.449 00:09:46.459 what we do here is like I said we're
00:09:48.310 00:09:48.320 running through all the calculations so
00:09:49.810 00:09:49.820 based on all the previous information
00:09:51.400 00:09:51.410 we've entered this all factors into the
00:09:53.860 00:09:53.870 tube sheet thickness so what we'll do
00:09:56.139 00:09:56.149 here is we'll fill out the remaining
00:09:57.970 00:09:57.980 information so the tube layer pattern
00:09:59.829 00:09:59.839 you know is it going to be a 30-degree
00:10:01.449 00:10:01.459 triangular layout 45 degrees square 60
00:10:04.000 00:10:04.010 degree or 90 degrees
00:10:05.109 00:10:05.119 I'll just leave it at 45 and then we'll
00:10:08.379 00:10:08.389 look at the tube related inputs so how
00:10:10.209 00:10:10.219 many tubes do we have in this exchanger
00:10:12.039 00:10:12.049 what's the tube pitch how many two
00:10:14.199 00:10:14.209 passes are there well we have a pass
00:10:15.639 00:10:15.649 partition in here and then the radius to
00:10:18.009 00:10:18.019 outermost tube Center based on all of
00:10:21.219 00:10:21.229 this we're going to run through and
00:10:23.259 00:10:23.269 we're going to tell you what the
00:10:24.069 00:10:24.079 thicknesses do the asme rules as well as
00:10:26.859 00:10:26.869 tema so you can see the ASME rules is a
00:10:29.139 00:10:29.149 bit lower than the tema
00:10:30.209 00:10:30.219 but they're really really close so what
00:10:32.349 00:10:32.359 we're gonna do is we're going to say the
00:10:34.269 00:10:34.279 thickness here is one and three-eighths
00:10:37.059 00:10:37.069 like so then from here we can fill out
00:10:40.839 00:10:40.849 any other information we may have for
00:10:43.179 00:10:43.189 example some material options you know
00:10:44.739 00:10:44.749 as a tube she can be normalized will be
00:10:46.419 00:10:46.429 produced a fine grain practice will be
00:10:48.009 00:10:48.019 impacted or even post while heat treated
00:10:50.789 00:10:50.799 we can then choose if we want to make
00:10:53.019 00:10:53.029 the shell side integral or gasketed and
00:10:55.779 00:10:55.789 the same with the tube side so if you
00:10:56.979 00:10:56.989 would like to have a gasket of
00:10:58.779 00:10:58.789 configuration so it's flanged on both
00:11:00.249 00:11:00.259 ends you could select that and we could
00:11:02.529 00:11:02.539 look up the flanges for you likewise we
00:11:05.349 00:11:05.359 can also specify step tube sheet so if
00:11:07.179 00:11:07.189 you got confined gaskets we can also
00:11:08.829 00:11:08.839 step in the tube sheet for you as well
00:11:11.339 00:11:11.349 but let's keep moving on so what I'm
00:11:13.719 00:11:13.729 gonna do is click Next and then we've
00:11:17.199 00:11:17.209 got the tube the tube sheet joint
00:11:18.459 00:11:18.469 calculations that we need to look up now
00:11:20.349 00:11:20.359 we have both the appendix a calculation
00:11:22.419 00:11:22.429 method and as well as the uhx so have
00:11:25.779 00:11:25.789 you decided to go with the uhx will look
00:11:27.399 00:11:27.409 up will determine the Philip weld size
00:11:29.979 00:11:29.989 for you based on the sketches that you
00:11:31.629 00:11:31.639 choose like so or you can choose to do
00:11:35.589 00:11:35.599 an appendix a analysis and I'll take F
00:11:38.439 00:11:38.449 right here okay and keep in mind as
00:11:42.069 00:11:42.079 we're selecting these we can always come
00:11:43.749 00:11:43.759 back in and change these inputs
00:11:44.979 00:11:44.989 afterwards as well so we'll do is we'll
00:11:48.159 00:11:48.169 click Next
00:11:49.199 00:11:49.209 and then we come to the nozzles page now
00:11:52.959 00:11:52.969 compressed will put an inlet and an
00:11:54.189 00:11:54.199 outlet and also both on the shell side
00:11:56.169 00:11:56.179 and the tube side for you and we can
00:11:57.729 00:11:57.739 also put some exhilerated connections on
00:11:59.409 00:11:59.419 here as well now what I'm going to do is
00:12:01.329 00:12:01.339 I'm actually gonna take these off and
00:12:02.469 00:12:02.479 I'm going to show you how we're gonna
00:12:03.249 00:12:03.259 add nozzles on afterwards so I'll just
00:12:05.409 00:12:05.419 take uncheck them here now once I get to
00:12:08.889 00:12:08.899 this point what I'm going to do is click
00:12:10.209 00:12:10.219 finish
00:12:11.340 00:12:11.350 and what this will do is create the
00:12:13.710 00:12:13.720 exchange if for you as you see right
00:12:15.600 00:12:15.610 here so we can move this around we can
00:12:18.930 00:12:18.940 rotate it things like that now what we
00:12:23.190 00:12:23.200 can do is we can make any edits to this
00:12:25.020 00:12:25.030 exchanger so let's say for example I
00:12:28.080 00:12:28.090 want to make my channel cylinder a
00:12:29.970 00:12:29.980 little bit shorter well what we can do
00:12:31.740 00:12:31.750 is we can edit this heat exchanger so
00:12:33.840 00:12:33.850 what you would do is you would right
00:12:34.980 00:12:34.990 click on your heat exchanger and you'd
00:12:37.050 00:12:37.060 select tube sheet and this is going to
00:12:39.660 00:12:39.670 open the heat exchanger wizard back up
00:12:41.490 00:12:41.500 so you may notice now that all of our
00:12:44.010 00:12:44.020 pages are tabbed along the top so for
00:12:46.080 00:12:46.090 example if you want to come back in to
00:12:48.150 00:12:48.160 the design conditions page maybe we want
00:12:49.590 00:12:49.600 to add in another design condition or we
00:12:51.240 00:12:51.250 want to modify one of them we can now
00:12:52.770 00:12:52.780 make edits to this heat exchanger but
00:12:56.010 00:12:56.020 let's say I want to make the channel
00:12:57.180 00:12:57.190 shoulder so I would come to the channel
00:12:59.340 00:12:59.350 page and I would take a look and say ok
00:13:02.400 00:13:02.410 my channel cylinder length let's make
00:13:03.900 00:13:03.910 this 15 inches and I'll do the same for
00:13:06.030 00:13:06.040 the rear tight that in I can click OK
00:13:08.910 00:13:08.920 and as you can see the channel cylinders
00:13:12.660 00:13:12.670 have been shortened up a little bit ok
00:13:15.720 00:13:15.730 so I had mentioned to you that's how we
00:13:18.210 00:13:18.220 design the heat exchangers in the wizard
00:13:19.650 00:13:19.660 but what if we want to start putting
00:13:20.760 00:13:20.770 some additional information on it for
00:13:23.400 00:13:23.410 example nozzles let's let's put some
00:13:25.110 00:13:25.120 nozzles on this well we can also do some
00:13:27.420 00:13:27.430 of the freeform modeling that many of
00:13:29.280 00:13:29.290 our users are accustomed to so for
00:13:31.620 00:13:31.630 example let's say I want add a nozzle
00:13:33.060 00:13:33.070 what I could do is come up to my nozzle
00:13:34.980 00:13:34.990 menu I could select detail design and we
00:13:38.610 00:13:38.620 could go through our nozzle dialog so
00:13:41.400 00:13:41.410 for example let's model this as a type 2
00:13:43.800 00:13:43.810 so I'll take a nozzle neck with a Repat
00:13:46.400 00:13:46.410 I'll leave it as a nozzle make it radio
00:13:49.370 00:13:49.380 then all we're going to do is specify
00:13:51.990 00:13:52.000 the drawing mark and the identifier so
00:13:53.910 00:13:53.920 this is up to you if it's an inlet or
00:13:55.290 00:13:55.300 outlet however you want to name it and
00:13:57.540 00:13:57.550 then we'll select the material from the
00:14:00.720 00:14:00.730 pulldown list and this is what we've
00:14:01.830 00:14:01.840 seen before same with the pad all right
00:14:05.760 00:14:05.770 then what I'm gonna do is I'm going to
00:14:06.870 00:14:06.880 drop down in the middle I'm gonna size
00:14:08.490 00:14:08.500 my nozzle neck now you can type in your
00:14:10.890 00:14:10.900 own inner diameter nominal thickness
00:14:12.480 00:14:12.490 typically would do this if you have a
00:14:13.830 00:14:13.840 very odd ball nozzle for maybe a 13-inch
00:14:16.590 00:14:16.600 nose over 17-inch things like that well
00:14:19.530 00:14:19.540 we're gonna do is just go to the
00:14:20.520 00:14:20.530 standard size lookup right here and
00:14:23.160 00:14:23.170 we're going to take a 10-inch nozzle
00:14:25.060 00:14:25.070 and we're gonna start with standard
00:14:26.319 00:14:26.329 schedule so I'll click OK and this
00:14:29.139 00:14:29.149 information will get pulled across so at
00:14:32.050 00:14:32.060 this point now what I would do is I
00:14:33.460 00:14:33.470 would add a flange on to this nozzle and
00:14:35.710 00:14:35.720 we're gonna do that by coming back up
00:14:38.499 00:14:38.509 here and choosing whether we want to add
00:14:40.660 00:14:40.670 in a s maybe 16 5 flange or if we'd like
00:14:43.300 00:14:43.310 to design one using the appendix 2
00:14:44.980 00:14:44.990 flange analysis so let's just how to be
00:14:47.410 00:14:47.420 sixteen five flange so I'll just click
00:14:49.780 00:14:49.790 on this button here and this input just
00:14:52.420 00:14:52.430 very basic inputs we just need to know
00:14:54.790 00:14:54.800 the material the flange type and the
00:14:57.430 00:14:57.440 flange class so let's take a 300 class
00:14:59.980 00:14:59.990 flange we already know what's going on
00:15:02.019 00:15:02.029 to a 10-inch nozzle so compresses look
00:15:03.879 00:15:03.889 that up for us then we just need to know
00:15:06.009 00:15:06.019 some bolting information like gasket
00:15:08.980 00:15:08.990 this details and the radiography of how
00:15:11.410 00:15:11.420 we're gonna x-ray the the scene once we
00:15:13.749 00:15:13.759 weld it on so I'll go ahead and click OK
00:15:16.389 00:15:16.399 here and as you can see the flange has
00:15:18.670 00:15:18.680 been added on to the end of the nozzle
00:15:20.259 00:15:20.269 neck so now what do I need to do I just
00:15:22.900 00:15:22.910 need to locate it onto the vessel that's
00:15:25.240 00:15:25.250 gonna take place down here now let's say
00:15:27.610 00:15:27.620 this was going to be on the front
00:15:29.079 00:15:29.089 channel so what I would do is I would
00:15:31.960 00:15:31.970 select front Channel right here and then
00:15:34.960 00:15:34.970 I just need to know an offset so I know
00:15:36.579 00:15:36.589 I know the length is 15 inches so let's
00:15:38.769 00:15:38.779 put it halfway I'm it also put 7.5
00:15:41.740 00:15:41.750 inches and I'll leave it on the top and
00:15:44.670 00:15:44.680 then I need to give it a projection
00:15:46.689 00:15:46.699 distance now this distance is going to
00:15:48.220 00:15:48.230 be taken from the center of the cylinder
00:15:49.930 00:15:49.940 to the face of the flange now if you
00:15:52.600 00:15:52.610 know this dimension great if you don't
00:15:54.490 00:15:54.500 no problem let's say you get an external
00:15:56.980 00:15:56.990 projection length maybe it needs to
00:15:58.509 00:15:58.519 project out 9 inches well if you do what
00:16:02.019 00:16:02.029 you can do is click on this button below
00:16:03.250 00:16:03.260 it says calculate minimum R from desired
00:16:05.740 00:16:05.750 external projection lengths like so and
00:16:08.139 00:16:08.149 we can type in our projection so I'll
00:16:09.910 00:16:09.920 type in 9 inches click OK and we'll
00:16:13.660 00:16:13.670 calculate this value for you so this
00:16:16.120 00:16:16.130 first screen is really just setting up
00:16:17.500 00:16:17.510 the nozzle so let's go to the next
00:16:19.150 00:16:19.160 screen and see if this meets code
00:16:21.819 00:16:21.829 criteria so I'll click Next as you can
00:16:25.660 00:16:25.670 see here's a cross-section of you in the
00:16:27.639 00:16:27.649 nozzle so what we'll need to do is first
00:16:32.259 00:16:32.269 decide is this meeting code criterion
00:16:34.269 00:16:34.279 what we do is you come down here and we
00:16:37.540 00:16:37.550 can look at our status bar
00:16:38.870 00:16:38.880 now this nozzle is actually being
00:16:41.120 00:16:41.130 designed currently with the rules of
00:16:42.410 00:16:42.420 Appendix 1-10 so instead of having the
00:16:44.780 00:16:44.790 classic air replacement method we're
00:16:46.340 00:16:46.350 actually looking at the primary stress
00:16:47.900 00:16:47.910 and we're gonna compare it to the
00:16:48.800 00:16:48.810 allowable stress so my primary stress is
00:16:51.439 00:16:51.449 just under 20,000 but my allowable
00:16:53.509 00:16:53.519 stress is 30,000 so this is this is
00:16:55.699 00:16:55.709 passing code but one thing we might want
00:16:58.910 00:16:58.920 to do is say well do I even have to have
00:17:00.710 00:17:00.720 a reinforcing pad you know my stress is
00:17:02.689 00:17:02.699 you know well under the allowable let's
00:17:04.610 00:17:04.620 take it off so I'll click previous and
00:17:07.069 00:17:07.079 we can change this back to a type 1 I'm
00:17:09.770 00:17:09.780 gonna click next and as you see my
00:17:12.470 00:17:12.480 primary stresses increase about 26,000
00:17:15.260 00:17:15.270 but I'm still under the allowable stress
00:17:16.760 00:17:16.770 okay so let's go ahead and click OK here
00:17:19.760 00:17:19.770 and as you can see the nozzle has been
00:17:22.220 00:17:22.230 added onto the cylinder now one other
00:17:25.610 00:17:25.620 thing you may notice is that I've placed
00:17:27.559 00:17:27.569 it on a longitudinal seam let's rotate
00:17:30.830 00:17:30.840 that seat and how we do that is when we
00:17:33.770 00:17:33.780 have longitudinal seams on the heat
00:17:35.360 00:17:35.370 exchanger along things button here will
00:17:37.610 00:17:37.620 appear so if I click on this you can see
00:17:40.310 00:17:40.320 here here's a 2d shell rollout and we
00:17:42.500 00:17:42.510 can see right here I have a longitudinal
00:17:44.899 00:17:44.909 seam going right through my nozzle now
00:17:46.850 00:17:46.860 this is actually how it's gonna be
00:17:48.980 00:17:48.990 constructed that's fine we just have to
00:17:50.659 00:17:50.669 go edit the nozzle and there's an option
00:17:52.399 00:17:52.409 there it says it's the nozzles through a
00:17:54.110 00:17:54.120 category a joint but let's move it so
00:17:57.230 00:17:57.240 I'm going to move it based on angular
00:17:58.610 00:17:58.620 position and I'm gonna move it to 270
00:18:04.970 00:18:04.980 degrees I'll click OK
00:18:09.600 00:18:09.610 and as you can see the seam has been
00:18:11.310 00:18:11.320 moved okay
00:18:12.870 00:18:12.880 so that's an overview of the modeling of
00:18:14.630 00:18:14.640 the heat exchanger now what are some of
00:18:17.220 00:18:17.230 the other options we have available to
00:18:18.690 00:18:18.700 us if you look down the bottom right
00:18:20.790 00:18:20.800 hand corner you'll see here we have
00:18:22.740 00:18:22.750 design us to have one in 2013 this is
00:18:26.430 00:18:26.440 what we call our status bar now if you
00:18:28.890 00:18:28.900 right-click on any of these some options
00:18:30.330 00:18:30.340 up here so for example alright click on
00:18:32.340 00:18:32.350 design you'll see here we have a design
00:18:34.290 00:18:34.300 mode and a rating mode our design mode
00:18:36.660 00:18:36.670 is meant for new construction new
00:18:38.160 00:18:38.170 fabrication and what we'll do is we'll
00:18:40.320 00:18:40.330 enforce minimum code thicknesses now on
00:18:42.720 00:18:42.730 the flip side this we also have a rating
00:18:44.130 00:18:44.140 mode so if you'd like to rewrite this
00:18:45.900 00:18:45.910 exchanger maybe you're doing some
00:18:47.970 00:18:47.980 alterations or some repair work we'll
00:18:50.010 00:18:50.020 want to put in two rating mode and what
00:18:51.600 00:18:51.610 we'll do is we'll based on the geometry
00:18:53.520 00:18:53.530 to give us we'll de-rate the heat
00:18:54.990 00:18:55.000 exchanger for you we also have US
00:18:58.560 00:18:58.570 customary as well as metric units
00:19:01.730 00:19:01.740 division one and then the 2013 is the
00:19:04.590 00:19:04.600 code edition now if I right click on
00:19:06.000 00:19:06.010 this what compressed does is gives you
00:19:08.040 00:19:08.050 all the previous editions and in
00:19:09.450 00:19:09.460 dentists now we go back to 1995 so if
00:19:12.000 00:19:12.010 you are doing any rear eights or
00:19:13.350 00:19:13.360 alterations you can do them to the
00:19:15.180 00:19:15.190 original code of construction okay so
00:19:19.560 00:19:19.570 let's run the code calculations now take
00:19:21.390 00:19:21.400 a look at the heat exchanger so in order
00:19:23.250 00:19:23.260 to do this what we'll do is we'll come
00:19:24.510 00:19:24.520 up to the Action menu and we'll select
00:19:27.360 00:19:27.370 perform code calculations right here
00:19:32.180 00:19:32.190 okay so here's our output report now
00:19:34.620 00:19:34.630 this is being currently viewed in the
00:19:36.060 00:19:36.070 HTML version if you click on the PDF
00:19:38.910 00:19:38.920 icon we'll switch it over to a PDF and
00:19:41.280 00:19:41.290 we can customize our report so you can
00:19:42.990 00:19:43.000 actually remove reports minimize reports
00:19:45.540 00:19:45.550 if you don't want them as long we can do
00:19:47.760 00:19:47.770 that but I'm going to show you a few
00:19:48.810 00:19:48.820 things in the HTML version so what we
00:19:51.540 00:19:51.550 have in there HTML our summer reports
00:19:53.880 00:19:53.890 here which just summarize the design so
00:19:58.200 00:19:58.210 the deficiency summary the pressure
00:19:59.940 00:19:59.950 summary the radiography summary
00:20:01.410 00:20:01.420 hydrostatic test things like that so for
00:20:04.440 00:20:04.450 example if you were to click on the
00:20:05.520 00:20:05.530 hydrostatic test you'll see here here
00:20:08.160 00:20:08.170 all the components on the heat exchanger
00:20:09.330 00:20:09.340 the local test pressure but more
00:20:12.240 00:20:12.250 importantly the stress during tests so
00:20:14.520 00:20:14.530 will actually calculate the stress for
00:20:15.990 00:20:16.000 you compare it to the allowable stress
00:20:19.690 00:20:19.700 likewise all of the individual
00:20:22.040 00:20:22.050 components will get their own report so
00:20:23.720 00:20:23.730 for example the fraud channel it's a
00:20:25.460 00:20:25.470 cylinder so here would be a cylinder
00:20:27.230 00:20:27.240 report for you and everything is broken
00:20:29.540 00:20:29.550 down for you so you have a full paper
00:20:30.980 00:20:30.990 true of how compresses determining all
00:20:32.720 00:20:32.730 of our values now for the tube sheet
00:20:36.560 00:20:36.570 analysis they'll be down here at the
00:20:39.140 00:20:39.150 bottom so let's click on the ASME tube
00:20:42.110 00:20:42.120 sheet report right here now one thing we
00:20:44.780 00:20:44.790 can do with our tube sheet reports is
00:20:47.090 00:20:47.100 that if we click on the heading right
00:20:48.380 00:20:48.390 here we can suppress the reports for it
00:20:51.920 00:20:51.930 so this makes it a lot easier to scroll
00:20:53.480 00:20:53.490 through so for example I want to take a
00:20:56.120 00:20:56.130 look at the design thickness summary or
00:21:00.020 00:21:00.030 the pressures so we can minimize them
00:21:03.650 00:21:03.660 expand them things like that but let's
00:21:06.230 00:21:06.240 take a look at the calculations of the
00:21:07.820 00:21:07.830 operating condition so what we do is we
00:21:10.370 00:21:10.380 lay out every step from uhx 13 because
00:21:12.800 00:21:12.810 this is a fixed exchanger
00:21:14.680 00:21:14.690 what we'll do is we'll lay out all the
00:21:16.640 00:21:16.650 formulas that we use and then what we do
00:21:19.880 00:21:19.890 is down below or all the calculations
00:21:21.860 00:21:21.870 with the values so you have a full paper
00:21:23.840 00:21:23.850 trail of what compress is doing so if
00:21:25.640 00:21:25.650 you'd like to investigate something
00:21:26.990 00:21:27.000 again you can just minimize these maybe
00:21:29.780 00:21:29.790 you want to come to step 9 and look into
00:21:32.390 00:21:32.400 it a little bit further so as you can
00:21:33.980 00:21:33.990 see we've run through all the different
00:21:34.820 00:21:34.830 load cases for you with all the values
00:21:37.040 00:21:37.050 so this makes it a lot easy to backtrack
00:21:38.570 00:21:38.580 if you're trying to investigate anything
00:21:41.560 00:21:41.570 so let's say we're in this report and we
00:21:43.970 00:21:43.980 want to switch back to the model we want
00:21:45.290 00:21:45.300 to go and make some changes maybe we
00:21:46.610 00:21:46.620 want to try to drop the tube sheet
00:21:47.720 00:21:47.730 thickness or increase it see what that
00:21:49.310 00:21:49.320 does well when we're in the reports what
00:21:51.920 00:21:51.930 you'll do is you'll click on the HTML
00:21:54.800 00:21:54.810 icon since we're in the HTML report like
00:21:57.230 00:21:57.240 so and we come back to the model
00:22:00.380 00:22:00.390 okay so we've touched on the modeling
00:22:02.090 00:22:02.100 aspect as well as the calculations now
00:22:05.030 00:22:05.040 let's fill out some of those forms so
00:22:07.520 00:22:07.530 when we build these heat exchangers we
00:22:09.350 00:22:09.360 need to fill out our u forms and
00:22:10.970 00:22:10.980 compress can do this for you
00:22:12.080 00:22:12.090 automatically
00:22:12.790 00:22:12.800 so what we would do is we'd simply come
00:22:15.770 00:22:15.780 up to our forms menu and we'd selected
00:22:18.620 00:22:18.630 asma u form so what we would do is
00:22:21.050 00:22:21.060 scroll across come down here it's like a
00:22:23.150 00:22:23.160 SME u5 form what this will do is open up
00:22:26.810 00:22:26.820 an HTML version of this form and
00:22:28.640 00:22:28.650 compress we'll fill out all the
00:22:30.260 00:22:30.270 information for you
00:22:32.299 00:22:32.309 so as you can see here's our form and
00:22:35.280 00:22:35.290 the information here at the top is
00:22:37.350 00:22:37.360 actually your information so you can
00:22:39.660 00:22:39.670 actually fill this out in a default
00:22:41.220 00:22:41.230 setting so that every time you generate
00:22:42.690 00:22:42.700 a form this information will come up
00:22:44.780 00:22:44.790 then all the technical information from
00:22:47.610 00:22:47.620 the vessel will be populated for you
00:22:49.350 00:22:49.360 from compress so you can scroll through
00:22:51.720 00:22:51.730 review it and then when you're happy
00:22:54.660 00:22:54.670 with it you can click finished and
00:22:57.770 00:22:57.780 compress will generate a PDF report of
00:23:00.299 00:23:00.309 this form like so so we can print this
00:23:03.810 00:23:03.820 off mail it in to the board things like
00:23:06.600 00:23:06.610 that
00:23:14.330 00:23:14.340 I'd like to thank you for watching this
