00:00:00.740 welcome to the compress heat exchanger 00:00:03.02000:00:03.030 demonstration today I'm going to go over 00:00:05.26900:00:05.279 some of the features that are available 00:00:06.26000:00:06.270 to you and compress and how we design 00:00:08.03000:00:08.040 heat exchangers so let's get started 00:00:15.91000:00:15.920 here's a typical heat exchange that I 00:00:18.26000:00:18.270 had modeled and compress so this is our 00:00:20.27000:00:20.280 fixed exchanger we have a Belle's 00:00:22.55000:00:22.560 expansion joint on it and we can take a 00:00:24.50000:00:24.510 look inside this exchanger - so we click 00:00:26.75000:00:26.760 on the show internals button you can see 00:00:28.88000:00:28.890 we'll also represent the tube sheet in 00:00:30.35000:00:30.360 the tube bundle for you and you can see 00:00:32.17900:00:32.189 some baffles there but how do we go 00:00:34.40000:00:34.410 about designing a seed exchanger with 00:00:37.94000:00:37.950 the heat exchanger module and compress 00:00:39.71000:00:39.720 we set up everything what we call a 00:00:41.27000:00:41.280 wizard and what this does is it's a a 00:00:43.46000:00:43.470 large dialog that contains all of the 00:00:45.31900:00:45.329 information for the heat exchanger 00:00:46.96000:00:46.970 benefit of doing it like this is that 00:00:49.79000:00:49.800 instead of having to model thing 00:00:50.87000:00:50.880 component by component we can simply 00:00:52.64000:00:52.650 just enter in all of the design data 00:00:54.62000:00:54.630 let's say from a team aspect sheet or a 00:00:56.51000:00:56.520 client spec sheet and we'll model the 00:00:58.28000:00:58.290 heat exchanger for you so why don't we 00:01:00.17000:01:00.180 go ahead and model this exchanger so 00:01:02.24000:01:02.250 what I'm going to do is come up to the 00:01:03.47000:01:03.480 file menu select new and we're going to 00:01:07.49000:01:07.500 select heat exchanger 00:01:12.42000:01:12.430 so this will open up our heat exchanger 00:01:13.98000:01:13.990 dialog and then we can start filling out 00:01:16.80000:01:16.810 the information so what we'll do in the 00:01:18.90000:01:18.910 heat exchangers will first ask you for 00:01:21.02000:01:21.030 general configuration and this is on our 00:01:23.37000:01:23.380 general options page that's just see in 00:01:24.81000:01:24.820 front of you so for example the exchange 00:01:27.12000:01:27.130 your type well we'd like to design a 00:01:28.53000:01:28.540 fixture stationery tube sheet we'd like 00:01:30.87000:01:30.880 to do a YouTube or even a floating tube 00:01:32.82000:01:32.830 sheet then we ask you for the 00:01:35.01000:01:35.020 calculation method compressed can design 00:01:37.80000:01:37.810 changes using the team rules the a/c new 00:01:40.26000:01:40.270 rules or both then we have few other 00:01:43.50000:01:43.510 options for the eights me such as our 00:01:45.15000:01:45.160 shell bands president would you like to 00:01:46.62000:01:46.630 use the operating temperatures things 00:01:48.27000:01:48.280 like that for the team of rules we can 00:01:50.96900:01:50.979 choose which addition you'd like to use 00:01:52.44000:01:52.450 whether you'd like to use the 7th 00:01:53.82000:01:53.830 addition the 8th edition or the ninth 00:01:55.62000:01:55.630 edition and then the team a class and 00:01:57.50000:01:57.510 then if there's going to be an expansion 00:01:59.60900:01:59.619 joint present from here we ask you the 00:02:03.35900:02:03.369 type of shell that we're going to be 00:02:04.56000:02:04.570 designing so this is gonna be a one-pass 00:02:06.18000:02:06.190 shell a two pass 00:02:07.62000:02:07.630 split flow things like that now the 00:02:10.80000:02:10.810 other item that we have on this dialogue 00:02:12.44900:02:12.459 is our heat exchanger defaults what we 00:02:15.15000:02:15.160 can do is set up defaults files so that 00:02:16.89000:02:16.900 once we enter in our heat exchanger we 00:02:19.41000:02:19.420 can save all these inputs and this is 00:02:21.24000:02:21.250 very handy if you're doing or you're 00:02:23.22000:02:23.230 building the same type of unit so for 00:02:26.16000:02:26.170 example if your company specializes in 00:02:28.29000:02:28.300 three different sizes of units well you 00:02:30.84000:02:30.850 can save let's say the 60 inch unit the 00:02:33.12000:02:33.130 90 inch unit and maybe the hundred 00:02:34.65000:02:34.660 twenty inch unit so if a client calls 00:02:36.24000:02:36.250 and says I need a sixty inch unit we can 00:02:38.37000:02:38.380 load this defaults file in and we can 00:02:40.94900:02:40.959 make any slight changes we may need to 00:02:42.50900:02:42.519 so what would you do is just simply 00:02:44.43000:02:44.440 select defaults file here and when you 00:02:48.00000:02:48.010 save it you just simply go and look it 00:02:49.94900:02:49.959 up like so so I'll loading the heat 00:02:52.11000:02:52.120 exchanger demo click open and it'll get 00:02:55.92000:02:55.930 loaded now you can also create a new 00:02:58.25900:02:58.269 default file so this is a new exchanger 00:03:00.39000:03:00.400 you can save all these inputs as you're 00:03:02.31000:03:02.320 going along and then save them 00:03:03.60000:03:03.610 afterwards as well ok so this page is 00:03:06.36000:03:06.370 set right now and I've loaded in my heat 00:03:08.78900:03:08.799 exchanger demo defaults so what I'm 00:03:10.77000:03:10.780 going to do is click Next now the first 00:03:14.16000:03:14.170 few pages for the heat exchanger 00:03:15.81000:03:15.820 dialogue are going to be for the design 00:03:17.34000:03:17.350 conditions we're going to look at the 00:03:18.63000:03:18.640 tube side design conditions then we're 00:03:20.46000:03:20.470 going to look at the shell side design 00:03:21.66000:03:21.670 conditions the tube sheet design 00:03:23.43000:03:23.440 conditions and then some bellows joint 00:03:25.68000:03:25.690 can do 00:03:26.25000:03:26.260 and liquid levels so for the tube side 00:03:30.72000:03:30.730 design conditions we can set up multiple 00:03:33.50000:03:33.510 conditions so for example I've got four 00:03:36.24000:03:36.250 set up here I have the operating 00:03:39.44000:03:39.450 condition the startup condition the 00:03:42.30000:03:42.310 shutdown and the up set and these are 00:03:43.97900:03:43.989 what I set up so you can name them 00:03:45.56900:03:45.579 anything you want and then based on this 00:03:48.60000:03:48.610 we just go through some very basic 00:03:50.27000:03:50.280 inputs so for example the internal 00:03:53.13000:03:53.140 design pressure the internal design 00:03:55.17000:03:55.180 temperature the external design pressure 00:03:57.99000:03:58.000 and then the operating pressure and we 00:04:00.21000:04:00.220 would do this for each one of our 00:04:01.25900:04:01.269 conditions then we're going to select 00:04:04.61900:04:04.629 the materials for the tube side 00:04:06.08900:04:06.099 components so for example we have the 00:04:08.81900:04:08.829 tube right here we just look the 00:04:10.92000:04:10.930 material from the pulldown list and you 00:04:12.59900:04:12.609 select the tube that you'd like to use 00:04:15.28900:04:15.299 from here we'll just need to know the 00:04:17.69900:04:17.709 tube mean metal temperature for each of 00:04:19.74000:04:19.750 the conditions if you'd like to see some 00:04:21.84000:04:21.850 material properties you can click on the 00:04:24.30000:04:24.310 show material properties button right 00:04:25.86000:04:25.870 here and you can see we're compresses 00:04:27.77900:04:27.789 pulling a lot of the information from 00:04:29.61000:04:29.620 for example the thermal expansion 00:04:30.90000:04:30.910 coefficients ores the yield stress 00:04:33.39000:04:33.400 source things like that I'm just gonna 00:04:35.55000:04:35.560 hide this and then we're gonna do the 00:04:37.83000:04:37.840 same thing for the channel cylinder so 00:04:39.96000:04:39.970 again from the pulldown menu we're just 00:04:41.61000:04:41.620 going to select the material that we're 00:04:42.93000:04:42.940 going to build the channel out of so 00:04:46.23000:04:46.240 what I'm going to do is I'm going to 00:04:47.07000:04:47.080 click Next and then we're going to do 00:04:49.80000:04:49.810 the same thing for the shell side 00:04:51.29000:04:51.300 conditions as well so for example we 00:04:53.82000:04:53.830 have our operating startup shut down up 00:04:55.98000:04:55.990 side condition we just need to enter in 00:04:58.02000:04:58.030 the pressure and temperatures external 00:05:00.45000:05:00.460 design pressure and the operating 00:05:02.01000:05:02.020 pressure and then select the material 00:05:04.37900:05:04.389 and the shell mean metal temperature so 00:05:08.40000:05:08.410 again I'll click Next here then we come 00:05:11.07000:05:11.080 to the tube sheets page now since we've 00:05:12.93000:05:12.940 already set up the shell side and the 00:05:14.67000:05:14.680 tube side design conditions we already 00:05:16.17000:05:16.180 know what pressure and temperature is 00:05:17.27900:05:17.289 acting on either side so really with the 00:05:19.32000:05:19.330 tube sheet we just need to know the 00:05:21.12000:05:21.130 material like so and then the mean metal 00:05:25.29000:05:25.300 temperature as well so again from here 00:05:28.29000:05:28.300 I'll just click Next 00:05:29.27900:05:29.289 and because I have a bellows expansion 00:05:32.12900:05:32.139 joint set up in this defaults file will 00:05:34.52900:05:34.539 ask you for the design conditions for 00:05:36.00000:05:36.010 this as well mainly we're going to ask 00:05:37.56000:05:37.570 you for the material 00:05:39.43900:05:39.449 alright I'll collect next then we can 00:05:42.86900:05:42.879 specify a liquid level acting on our 00:05:44.60900:05:44.619 heat exchanger why is this important 00:05:46.88900:05:46.899 well compress will automatically account 00:05:49.19900:05:49.209 for the static head that might be acting 00:05:50.78900:05:50.799 on the tube sheet and this is part of 00:05:52.46900:05:52.479 the code requirements we need to 00:05:53.63900:05:53.649 consider all loadings acting on the tube 00:05:55.46900:05:55.479 sheet so there is a liquid level we can 00:05:57.98900:05:57.999 specify it here ok so so far we've set 00:06:02.36900:06:02.379 up our design conditions 00:06:03.71900:06:03.729 so now compresses everything that you 00:06:05.57900:06:05.589 need to start selecting sizes ways so 00:06:07.61900:06:07.629 the next few pages are going to be the 00:06:09.05900:06:09.069 component portion of the heat exchanger 00:06:11.48900:06:11.499 so I'll click Next and we're going to 00:06:14.81900:06:14.829 start with the tube geometry Michelle 00:06:16.58900:06:16.599 and then any baffles so the first thing 00:06:19.67900:06:19.689 we're going to do is we're going to look 00:06:20.69900:06:20.709 at the tube geometry so what we'll need 00:06:22.79900:06:22.809 to know is the length between the outer 00:06:24.56900:06:24.579 tube sheets so essentially the overall 00:06:26.06900:06:26.079 length of your tube bundle so we'll just 00:06:27.83900:06:27.849 leave it at 120 inches and then we need 00:06:30.38900:06:30.399 to select the tube diameter and the wall 00:06:32.27900:06:32.289 thickness now you can type in this 00:06:33.71900:06:33.729 information if you'd like or we can 00:06:35.51900:06:35.529 select a tube from here and we can look 00:06:37.91900:06:37.929 up you know the specific size that we'd 00:06:39.83900:06:39.849 like to use and click OK now one thing 00:06:43.52900:06:43.539 you may notice here is that beside the 00:06:45.44900:06:45.459 wall thickness input there's a block 00:06:47.18900:06:47.199 text well what does this mean this is a 00:06:49.58900:06:49.599 calculated minimum so as we're designing 00:06:52.01900:06:52.029 our heat exchanger we're constantly 00:06:53.48900:06:53.499 running calculations or in the 00:06:54.98900:06:54.999 background so based on all the inputs we 00:06:57.11900:06:57.129 have so far this is the minimum tube 00:06:59.27900:06:59.289 wall thickness that we need to account 00:07:00.71900:07:00.729 for and keep in mind there's also going 00:07:02.69900:07:02.709 to be a tube mil tolerance applied to 00:07:04.88900:07:04.899 this as well all right from here we just 00:07:08.51900:07:08.529 need to know the tube expansion depth 00:07:10.07900:07:10.089 ratio type that in and then we can move 00:07:12.62900:07:12.639 on to the next component which in our 00:07:14.39900:07:14.409 case is going to be the shell so again 00:07:16.94900:07:16.959 just type in the inner diameter you have 00:07:18.80900:07:18.819 and the thickness will tell you what the 00:07:21.20900:07:21.219 minimum needs to be if there's any 00:07:23.15900:07:23.169 corrosion on the inside or outside of 00:07:24.71900:07:24.729 the show and then the MDM T now this MD 00:07:28.04900:07:28.059 MT input is a target MDM T so this is 00:07:30.32900:07:30.339 what we're trying to design to more than 00:07:33.56900:07:33.579 likely this might actually be able to go 00:07:34.70900:07:34.719 a lot lower than 0 degrees but if it's 00:07:36.95900:07:36.969 not let's say it's only good to 10 00:07:38.60900:07:38.619 degrees we're gonna warn you in the 00:07:40.31900:07:40.329 report all right and the last thing 00:07:44.72900:07:44.739 we're gonna do here is we're going to 00:07:45.77900:07:45.789 specify baffles now you can do this in 00:07:48.17900:07:48.189 two ways if you know where the baffles 00:07:49.67900:07:49.689 are laid out now we can enter in them 00:07:51.44900:07:51.459 for me 00:07:52.20900:07:52.219 but if you don't what we what you could 00:07:54.12900:07:54.139 do is just take the battlezone for the 00:07:55.51000:07:55.520 time being get the rest of the heat 00:07:57.76000:07:57.770 exchanger set and then come back in and 00:07:59.08000:07:59.090 add them but again and there's our 00:08:01.08900:08:01.099 baffles present we just activate this 00:08:03.39900:08:03.409 option you can have compressed 00:08:05.26000:08:05.270 automatically place the baffles for you 00:08:07.60000:08:07.610 or you can turn this off and you can 00:08:08.92000:08:08.930 manually space them where you'd like 00:08:11.67900:08:11.689 them on the heat exchanger okay so the 00:08:14.64900:08:14.659 tubes and shell page is done right now 00:08:16.20900:08:16.219 so what I'll do is I'll click Next and 00:08:18.39900:08:18.409 then we come to the channel page so this 00:08:21.04000:08:21.050 is where we're going to look at the 00:08:21.87900:08:21.889 front in the rear channel so up at the 00:08:24.39900:08:24.409 top here we have to decide well what 00:08:26.08000:08:26.090 type of channel are we going to use we 00:08:28.74900:08:28.759 can do a channel type which would 00:08:30.86900:08:30.879 encompass a bowl to cover or welded 00:08:33.49000:08:33.500 cover if you decide to go with a bowl to 00:08:35.50000:08:35.510 cover we can design the flanges using 00:08:37.71900:08:37.729 the appendix 2 rules or we can look up a 00:08:39.73000:08:39.740 B 16 v flange for you we can also do a 00:08:42.73000:08:42.740 reducer and then a bond and type now the 00:08:45.61000:08:45.620 front channel is currently set up with a 00:08:46.99000:08:47.000 bono type and I have an ellipsoidal head 00:08:48.93900:08:48.949 being used but I can also use an F and D 00:08:51.28000:08:51.290 head or a hemispherical head from here 00:08:55.00000:08:55.010 we just need to know the geometry of the 00:08:56.76900:08:56.779 head itself so first thing is the 00:08:59.71000:08:59.720 material and then the diameter the 00:09:02.25900:09:02.269 minimum thickness straight flange like 00:09:04.48000:09:04.490 things like that and then again we'll do 00:09:07.15000:09:07.160 the same thing for the channel cylinder 00:09:08.69900:09:08.709 once you get this set we'll switch over 00:09:11.25900:09:11.269 to the rear now if you have bonnets on 00:09:13.15000:09:13.160 both sides you could actually copy the 00:09:14.94900:09:14.959 front end property so you don't need to 00:09:16.30000:09:16.310 type the information in again but I 00:09:18.13000:09:18.140 chose to set this up as a bowl to cover 00:09:19.93000:09:19.940 and I've got an appendix to flange on 00:09:21.69900:09:21.709 this so once we get this all set what we 00:09:25.38900:09:25.399 can do is click Next and then we come to 00:09:29.19900:09:29.209 our expansion joint page the expansion 00:09:31.32900:09:31.339 joint page will just need to know 00:09:32.47000:09:32.480 geometry the expansion joint and then we 00:09:35.38000:09:35.390 can just type this information in the 00:09:36.97000:09:36.980 inputs here so again I'll click Next and 00:09:42.60000:09:42.610 then we come to the tube sheets page so 00:09:46.44900:09:46.459 what we do here is like I said we're 00:09:48.31000:09:48.320 running through all the calculations so 00:09:49.81000:09:49.820 based on all the previous information 00:09:51.40000:09:51.410 we've entered this all factors into the 00:09:53.86000:09:53.870 tube sheet thickness so what we'll do 00:09:56.13900:09:56.149 here is we'll fill out the remaining 00:09:57.97000:09:57.980 information so the tube layer pattern 00:09:59.82900:09:59.839 you know is it going to be a 30-degree 00:10:01.44900:10:01.459 triangular layout 45 degrees square 60 00:10:04.00000:10:04.010 degree or 90 degrees 00:10:05.10900:10:05.119 I'll just leave it at 45 and then we'll 00:10:08.37900:10:08.389 look at the tube related inputs so how 00:10:10.20900:10:10.219 many tubes do we have in this exchanger 00:10:12.03900:10:12.049 what's the tube pitch how many two 00:10:14.19900:10:14.209 passes are there well we have a pass 00:10:15.63900:10:15.649 partition in here and then the radius to 00:10:18.00900:10:18.019 outermost tube Center based on all of 00:10:21.21900:10:21.229 this we're going to run through and 00:10:23.25900:10:23.269 we're going to tell you what the 00:10:24.06900:10:24.079 thicknesses do the asme rules as well as 00:10:26.85900:10:26.869 tema so you can see the ASME rules is a 00:10:29.13900:10:29.149 bit lower than the tema 00:10:30.20900:10:30.219 but they're really really close so what 00:10:32.34900:10:32.359 we're gonna do is we're going to say the 00:10:34.26900:10:34.279 thickness here is one and three-eighths 00:10:37.05900:10:37.069 like so then from here we can fill out 00:10:40.83900:10:40.849 any other information we may have for 00:10:43.17900:10:43.189 example some material options you know 00:10:44.73900:10:44.749 as a tube she can be normalized will be 00:10:46.41900:10:46.429 produced a fine grain practice will be 00:10:48.00900:10:48.019 impacted or even post while heat treated 00:10:50.78900:10:50.799 we can then choose if we want to make 00:10:53.01900:10:53.029 the shell side integral or gasketed and 00:10:55.77900:10:55.789 the same with the tube side so if you 00:10:56.97900:10:56.989 would like to have a gasket of 00:10:58.77900:10:58.789 configuration so it's flanged on both 00:11:00.24900:11:00.259 ends you could select that and we could 00:11:02.52900:11:02.539 look up the flanges for you likewise we 00:11:05.34900:11:05.359 can also specify step tube sheet so if 00:11:07.17900:11:07.189 you got confined gaskets we can also 00:11:08.82900:11:08.839 step in the tube sheet for you as well 00:11:11.33900:11:11.349 but let's keep moving on so what I'm 00:11:13.71900:11:13.729 gonna do is click Next and then we've 00:11:17.19900:11:17.209 got the tube the tube sheet joint 00:11:18.45900:11:18.469 calculations that we need to look up now 00:11:20.34900:11:20.359 we have both the appendix a calculation 00:11:22.41900:11:22.429 method and as well as the uhx so have 00:11:25.77900:11:25.789 you decided to go with the uhx will look 00:11:27.39900:11:27.409 up will determine the Philip weld size 00:11:29.97900:11:29.989 for you based on the sketches that you 00:11:31.62900:11:31.639 choose like so or you can choose to do 00:11:35.58900:11:35.599 an appendix a analysis and I'll take F 00:11:38.43900:11:38.449 right here okay and keep in mind as 00:11:42.06900:11:42.079 we're selecting these we can always come 00:11:43.74900:11:43.759 back in and change these inputs 00:11:44.97900:11:44.989 afterwards as well so we'll do is we'll 00:11:48.15900:11:48.169 click Next 00:11:49.19900:11:49.209 and then we come to the nozzles page now 00:11:52.95900:11:52.969 compressed will put an inlet and an 00:11:54.18900:11:54.199 outlet and also both on the shell side 00:11:56.16900:11:56.179 and the tube side for you and we can 00:11:57.72900:11:57.739 also put some exhilerated connections on 00:11:59.40900:11:59.419 here as well now what I'm going to do is 00:12:01.32900:12:01.339 I'm actually gonna take these off and 00:12:02.46900:12:02.479 I'm going to show you how we're gonna 00:12:03.24900:12:03.259 add nozzles on afterwards so I'll just 00:12:05.40900:12:05.419 take uncheck them here now once I get to 00:12:08.88900:12:08.899 this point what I'm going to do is click 00:12:10.20900:12:10.219 finish 00:12:11.34000:12:11.350 and what this will do is create the 00:12:13.71000:12:13.720 exchange if for you as you see right 00:12:15.60000:12:15.610 here so we can move this around we can 00:12:18.93000:12:18.940 rotate it things like that now what we 00:12:23.19000:12:23.200 can do is we can make any edits to this 00:12:25.02000:12:25.030 exchanger so let's say for example I 00:12:28.08000:12:28.090 want to make my channel cylinder a 00:12:29.97000:12:29.980 little bit shorter well what we can do 00:12:31.74000:12:31.750 is we can edit this heat exchanger so 00:12:33.84000:12:33.850 what you would do is you would right 00:12:34.98000:12:34.990 click on your heat exchanger and you'd 00:12:37.05000:12:37.060 select tube sheet and this is going to 00:12:39.66000:12:39.670 open the heat exchanger wizard back up 00:12:41.49000:12:41.500 so you may notice now that all of our 00:12:44.01000:12:44.020 pages are tabbed along the top so for 00:12:46.08000:12:46.090 example if you want to come back in to 00:12:48.15000:12:48.160 the design conditions page maybe we want 00:12:49.59000:12:49.600 to add in another design condition or we 00:12:51.24000:12:51.250 want to modify one of them we can now 00:12:52.77000:12:52.780 make edits to this heat exchanger but 00:12:56.01000:12:56.020 let's say I want to make the channel 00:12:57.18000:12:57.190 shoulder so I would come to the channel 00:12:59.34000:12:59.350 page and I would take a look and say ok 00:13:02.40000:13:02.410 my channel cylinder length let's make 00:13:03.90000:13:03.910 this 15 inches and I'll do the same for 00:13:06.03000:13:06.040 the rear tight that in I can click OK 00:13:08.91000:13:08.920 and as you can see the channel cylinders 00:13:12.66000:13:12.670 have been shortened up a little bit ok 00:13:15.72000:13:15.730 so I had mentioned to you that's how we 00:13:18.21000:13:18.220 design the heat exchangers in the wizard 00:13:19.65000:13:19.660 but what if we want to start putting 00:13:20.76000:13:20.770 some additional information on it for 00:13:23.40000:13:23.410 example nozzles let's let's put some 00:13:25.11000:13:25.120 nozzles on this well we can also do some 00:13:27.42000:13:27.430 of the freeform modeling that many of 00:13:29.28000:13:29.290 our users are accustomed to so for 00:13:31.62000:13:31.630 example let's say I want add a nozzle 00:13:33.06000:13:33.070 what I could do is come up to my nozzle 00:13:34.98000:13:34.990 menu I could select detail design and we 00:13:38.61000:13:38.620 could go through our nozzle dialog so 00:13:41.40000:13:41.410 for example let's model this as a type 2 00:13:43.80000:13:43.810 so I'll take a nozzle neck with a Repat 00:13:46.40000:13:46.410 I'll leave it as a nozzle make it radio 00:13:49.37000:13:49.380 then all we're going to do is specify 00:13:51.99000:13:52.000 the drawing mark and the identifier so 00:13:53.91000:13:53.920 this is up to you if it's an inlet or 00:13:55.29000:13:55.300 outlet however you want to name it and 00:13:57.54000:13:57.550 then we'll select the material from the 00:14:00.72000:14:00.730 pulldown list and this is what we've 00:14:01.83000:14:01.840 seen before same with the pad all right 00:14:05.76000:14:05.770 then what I'm gonna do is I'm going to 00:14:06.87000:14:06.880 drop down in the middle I'm gonna size 00:14:08.49000:14:08.500 my nozzle neck now you can type in your 00:14:10.89000:14:10.900 own inner diameter nominal thickness 00:14:12.48000:14:12.490 typically would do this if you have a 00:14:13.83000:14:13.840 very odd ball nozzle for maybe a 13-inch 00:14:16.59000:14:16.600 nose over 17-inch things like that well 00:14:19.53000:14:19.540 we're gonna do is just go to the 00:14:20.52000:14:20.530 standard size lookup right here and 00:14:23.16000:14:23.170 we're going to take a 10-inch nozzle 00:14:25.06000:14:25.070 and we're gonna start with standard 00:14:26.31900:14:26.329 schedule so I'll click OK and this 00:14:29.13900:14:29.149 information will get pulled across so at 00:14:32.05000:14:32.060 this point now what I would do is I 00:14:33.46000:14:33.470 would add a flange on to this nozzle and 00:14:35.71000:14:35.720 we're gonna do that by coming back up 00:14:38.49900:14:38.509 here and choosing whether we want to add 00:14:40.66000:14:40.670 in a s maybe 16 5 flange or if we'd like 00:14:43.30000:14:43.310 to design one using the appendix 2 00:14:44.98000:14:44.990 flange analysis so let's just how to be 00:14:47.41000:14:47.420 sixteen five flange so I'll just click 00:14:49.78000:14:49.790 on this button here and this input just 00:14:52.42000:14:52.430 very basic inputs we just need to know 00:14:54.79000:14:54.800 the material the flange type and the 00:14:57.43000:14:57.440 flange class so let's take a 300 class 00:14:59.98000:14:59.990 flange we already know what's going on 00:15:02.01900:15:02.029 to a 10-inch nozzle so compresses look 00:15:03.87900:15:03.889 that up for us then we just need to know 00:15:06.00900:15:06.019 some bolting information like gasket 00:15:08.98000:15:08.990 this details and the radiography of how 00:15:11.41000:15:11.420 we're gonna x-ray the the scene once we 00:15:13.74900:15:13.759 weld it on so I'll go ahead and click OK 00:15:16.38900:15:16.399 here and as you can see the flange has 00:15:18.67000:15:18.680 been added on to the end of the nozzle 00:15:20.25900:15:20.269 neck so now what do I need to do I just 00:15:22.90000:15:22.910 need to locate it onto the vessel that's 00:15:25.24000:15:25.250 gonna take place down here now let's say 00:15:27.61000:15:27.620 this was going to be on the front 00:15:29.07900:15:29.089 channel so what I would do is I would 00:15:31.96000:15:31.970 select front Channel right here and then 00:15:34.96000:15:34.970 I just need to know an offset so I know 00:15:36.57900:15:36.589 I know the length is 15 inches so let's 00:15:38.76900:15:38.779 put it halfway I'm it also put 7.5 00:15:41.74000:15:41.750 inches and I'll leave it on the top and 00:15:44.67000:15:44.680 then I need to give it a projection 00:15:46.68900:15:46.699 distance now this distance is going to 00:15:48.22000:15:48.230 be taken from the center of the cylinder 00:15:49.93000:15:49.940 to the face of the flange now if you 00:15:52.60000:15:52.610 know this dimension great if you don't 00:15:54.49000:15:54.500 no problem let's say you get an external 00:15:56.98000:15:56.990 projection length maybe it needs to 00:15:58.50900:15:58.519 project out 9 inches well if you do what 00:16:02.01900:16:02.029 you can do is click on this button below 00:16:03.25000:16:03.260 it says calculate minimum R from desired 00:16:05.74000:16:05.750 external projection lengths like so and 00:16:08.13900:16:08.149 we can type in our projection so I'll 00:16:09.91000:16:09.920 type in 9 inches click OK and we'll 00:16:13.66000:16:13.670 calculate this value for you so this 00:16:16.12000:16:16.130 first screen is really just setting up 00:16:17.50000:16:17.510 the nozzle so let's go to the next 00:16:19.15000:16:19.160 screen and see if this meets code 00:16:21.81900:16:21.829 criteria so I'll click Next as you can 00:16:25.66000:16:25.670 see here's a cross-section of you in the 00:16:27.63900:16:27.649 nozzle so what we'll need to do is first 00:16:32.25900:16:32.269 decide is this meeting code criterion 00:16:34.26900:16:34.279 what we do is you come down here and we 00:16:37.54000:16:37.550 can look at our status bar 00:16:38.87000:16:38.880 now this nozzle is actually being 00:16:41.12000:16:41.130 designed currently with the rules of 00:16:42.41000:16:42.420 Appendix 1-10 so instead of having the 00:16:44.78000:16:44.790 classic air replacement method we're 00:16:46.34000:16:46.350 actually looking at the primary stress 00:16:47.90000:16:47.910 and we're gonna compare it to the 00:16:48.80000:16:48.810 allowable stress so my primary stress is 00:16:51.43900:16:51.449 just under 20,000 but my allowable 00:16:53.50900:16:53.519 stress is 30,000 so this is this is 00:16:55.69900:16:55.709 passing code but one thing we might want 00:16:58.91000:16:58.920 to do is say well do I even have to have 00:17:00.71000:17:00.720 a reinforcing pad you know my stress is 00:17:02.68900:17:02.699 you know well under the allowable let's 00:17:04.61000:17:04.620 take it off so I'll click previous and 00:17:07.06900:17:07.079 we can change this back to a type 1 I'm 00:17:09.77000:17:09.780 gonna click next and as you see my 00:17:12.47000:17:12.480 primary stresses increase about 26,000 00:17:15.26000:17:15.270 but I'm still under the allowable stress 00:17:16.76000:17:16.770 okay so let's go ahead and click OK here 00:17:19.76000:17:19.770 and as you can see the nozzle has been 00:17:22.22000:17:22.230 added onto the cylinder now one other 00:17:25.61000:17:25.620 thing you may notice is that I've placed 00:17:27.55900:17:27.569 it on a longitudinal seam let's rotate 00:17:30.83000:17:30.840 that seat and how we do that is when we 00:17:33.77000:17:33.780 have longitudinal seams on the heat 00:17:35.36000:17:35.370 exchanger along things button here will 00:17:37.61000:17:37.620 appear so if I click on this you can see 00:17:40.31000:17:40.320 here here's a 2d shell rollout and we 00:17:42.50000:17:42.510 can see right here I have a longitudinal 00:17:44.89900:17:44.909 seam going right through my nozzle now 00:17:46.85000:17:46.860 this is actually how it's gonna be 00:17:48.98000:17:48.990 constructed that's fine we just have to 00:17:50.65900:17:50.669 go edit the nozzle and there's an option 00:17:52.39900:17:52.409 there it says it's the nozzles through a 00:17:54.11000:17:54.120 category a joint but let's move it so 00:17:57.23000:17:57.240 I'm going to move it based on angular 00:17:58.61000:17:58.620 position and I'm gonna move it to 270 00:18:04.97000:18:04.980 degrees I'll click OK 00:18:09.60000:18:09.610 and as you can see the seam has been 00:18:11.31000:18:11.320 moved okay 00:18:12.87000:18:12.880 so that's an overview of the modeling of 00:18:14.63000:18:14.640 the heat exchanger now what are some of 00:18:17.22000:18:17.230 the other options we have available to 00:18:18.69000:18:18.700 us if you look down the bottom right 00:18:20.79000:18:20.800 hand corner you'll see here we have 00:18:22.74000:18:22.750 design us to have one in 2013 this is 00:18:26.43000:18:26.440 what we call our status bar now if you 00:18:28.89000:18:28.900 right-click on any of these some options 00:18:30.33000:18:30.340 up here so for example alright click on 00:18:32.34000:18:32.350 design you'll see here we have a design 00:18:34.29000:18:34.300 mode and a rating mode our design mode 00:18:36.66000:18:36.670 is meant for new construction new 00:18:38.16000:18:38.170 fabrication and what we'll do is we'll 00:18:40.32000:18:40.330 enforce minimum code thicknesses now on 00:18:42.72000:18:42.730 the flip side this we also have a rating 00:18:44.13000:18:44.140 mode so if you'd like to rewrite this 00:18:45.90000:18:45.910 exchanger maybe you're doing some 00:18:47.97000:18:47.980 alterations or some repair work we'll 00:18:50.01000:18:50.020 want to put in two rating mode and what 00:18:51.60000:18:51.610 we'll do is we'll based on the geometry 00:18:53.52000:18:53.530 to give us we'll de-rate the heat 00:18:54.99000:18:55.000 exchanger for you we also have US 00:18:58.56000:18:58.570 customary as well as metric units 00:19:01.73000:19:01.740 division one and then the 2013 is the 00:19:04.59000:19:04.600 code edition now if I right click on 00:19:06.00000:19:06.010 this what compressed does is gives you 00:19:08.04000:19:08.050 all the previous editions and in 00:19:09.45000:19:09.460 dentists now we go back to 1995 so if 00:19:12.00000:19:12.010 you are doing any rear eights or 00:19:13.35000:19:13.360 alterations you can do them to the 00:19:15.18000:19:15.190 original code of construction okay so 00:19:19.56000:19:19.570 let's run the code calculations now take 00:19:21.39000:19:21.400 a look at the heat exchanger so in order 00:19:23.25000:19:23.260 to do this what we'll do is we'll come 00:19:24.51000:19:24.520 up to the Action menu and we'll select 00:19:27.36000:19:27.370 perform code calculations right here 00:19:32.18000:19:32.190 okay so here's our output report now 00:19:34.62000:19:34.630 this is being currently viewed in the 00:19:36.06000:19:36.070 HTML version if you click on the PDF 00:19:38.91000:19:38.920 icon we'll switch it over to a PDF and 00:19:41.28000:19:41.290 we can customize our report so you can 00:19:42.99000:19:43.000 actually remove reports minimize reports 00:19:45.54000:19:45.550 if you don't want them as long we can do 00:19:47.76000:19:47.770 that but I'm going to show you a few 00:19:48.81000:19:48.820 things in the HTML version so what we 00:19:51.54000:19:51.550 have in there HTML our summer reports 00:19:53.88000:19:53.890 here which just summarize the design so 00:19:58.20000:19:58.210 the deficiency summary the pressure 00:19:59.94000:19:59.950 summary the radiography summary 00:20:01.41000:20:01.420 hydrostatic test things like that so for 00:20:04.44000:20:04.450 example if you were to click on the 00:20:05.52000:20:05.530 hydrostatic test you'll see here here 00:20:08.16000:20:08.170 all the components on the heat exchanger 00:20:09.33000:20:09.340 the local test pressure but more 00:20:12.24000:20:12.250 importantly the stress during tests so 00:20:14.52000:20:14.530 will actually calculate the stress for 00:20:15.99000:20:16.000 you compare it to the allowable stress 00:20:19.69000:20:19.700 likewise all of the individual 00:20:22.04000:20:22.050 components will get their own report so 00:20:23.72000:20:23.730 for example the fraud channel it's a 00:20:25.46000:20:25.470 cylinder so here would be a cylinder 00:20:27.23000:20:27.240 report for you and everything is broken 00:20:29.54000:20:29.550 down for you so you have a full paper 00:20:30.98000:20:30.990 true of how compresses determining all 00:20:32.72000:20:32.730 of our values now for the tube sheet 00:20:36.56000:20:36.570 analysis they'll be down here at the 00:20:39.14000:20:39.150 bottom so let's click on the ASME tube 00:20:42.11000:20:42.120 sheet report right here now one thing we 00:20:44.78000:20:44.790 can do with our tube sheet reports is 00:20:47.09000:20:47.100 that if we click on the heading right 00:20:48.38000:20:48.390 here we can suppress the reports for it 00:20:51.92000:20:51.930 so this makes it a lot easier to scroll 00:20:53.48000:20:53.490 through so for example I want to take a 00:20:56.12000:20:56.130 look at the design thickness summary or 00:21:00.02000:21:00.030 the pressures so we can minimize them 00:21:03.65000:21:03.660 expand them things like that but let's 00:21:06.23000:21:06.240 take a look at the calculations of the 00:21:07.82000:21:07.830 operating condition so what we do is we 00:21:10.37000:21:10.380 lay out every step from uhx 13 because 00:21:12.80000:21:12.810 this is a fixed exchanger 00:21:14.68000:21:14.690 what we'll do is we'll lay out all the 00:21:16.64000:21:16.650 formulas that we use and then what we do 00:21:19.88000:21:19.890 is down below or all the calculations 00:21:21.86000:21:21.870 with the values so you have a full paper 00:21:23.84000:21:23.850 trail of what compress is doing so if 00:21:25.64000:21:25.650 you'd like to investigate something 00:21:26.99000:21:27.000 again you can just minimize these maybe 00:21:29.78000:21:29.790 you want to come to step 9 and look into 00:21:32.39000:21:32.400 it a little bit further so as you can 00:21:33.98000:21:33.990 see we've run through all the different 00:21:34.82000:21:34.830 load cases for you with all the values 00:21:37.04000:21:37.050 so this makes it a lot easy to backtrack 00:21:38.57000:21:38.580 if you're trying to investigate anything 00:21:41.56000:21:41.570 so let's say we're in this report and we 00:21:43.97000:21:43.980 want to switch back to the model we want 00:21:45.29000:21:45.300 to go and make some changes maybe we 00:21:46.61000:21:46.620 want to try to drop the tube sheet 00:21:47.72000:21:47.730 thickness or increase it see what that 00:21:49.31000:21:49.320 does well when we're in the reports what 00:21:51.92000:21:51.930 you'll do is you'll click on the HTML 00:21:54.80000:21:54.810 icon since we're in the HTML report like 00:21:57.23000:21:57.240 so and we come back to the model 00:22:00.38000:22:00.390 okay so we've touched on the modeling 00:22:02.09000:22:02.100 aspect as well as the calculations now 00:22:05.03000:22:05.040 let's fill out some of those forms so 00:22:07.52000:22:07.530 when we build these heat exchangers we 00:22:09.35000:22:09.360 need to fill out our u forms and 00:22:10.97000:22:10.980 compress can do this for you 00:22:12.08000:22:12.090 automatically 00:22:12.79000:22:12.800 so what we would do is we'd simply come 00:22:15.77000:22:15.780 up to our forms menu and we'd selected 00:22:18.62000:22:18.630 asma u form so what we would do is 00:22:21.05000:22:21.060 scroll across come down here it's like a 00:22:23.15000:22:23.160 SME u5 form what this will do is open up 00:22:26.81000:22:26.820 an HTML version of this form and 00:22:28.64000:22:28.650 compress we'll fill out all the 00:22:30.26000:22:30.270 information for you 00:22:32.29900:22:32.309 so as you can see here's our form and 00:22:35.28000:22:35.290 the information here at the top is 00:22:37.35000:22:37.360 actually your information so you can 00:22:39.66000:22:39.670 actually fill this out in a default 00:22:41.22000:22:41.230 setting so that every time you generate 00:22:42.69000:22:42.700 a form this information will come up 00:22:44.78000:22:44.790 then all the technical information from 00:22:47.61000:22:47.620 the vessel will be populated for you 00:22:49.35000:22:49.360 from compress so you can scroll through 00:22:51.72000:22:51.730 review it and then when you're happy 00:22:54.66000:22:54.670 with it you can click finished and 00:22:57.77000:22:57.780 compress will generate a PDF report of 00:23:00.29900:23:00.309 this form like so so we can print this 00:23:03.81000:23:03.820 off mail it in to the board things like
