00:00:01.040 hi guys welcome to channel piping mantra 00:00:04.51900:00:04.529 this is the continuation to part two I 00:00:06.95000:00:06.960 will link part two of this video in 00:00:09.56000:00:09.570 description box below n the link must 00:00:11.99000:00:12.000 also be appearing in the solution box 00:00:13.99900:00:14.009 I will link the part one of the same 00:00:15.65000:00:15.660 video as well so please do watch those 00:00:18.05000:00:18.060 as well so forth out further ado let's 00:00:20.68900:00:20.699 get started on part three 00:00:22.16000:00:22.170 after all the required information has 00:00:24.80000:00:24.810 been collected for the piping design of 00:00:27.17000:00:27.180 the heat exchanger the first step is to 00:00:29.35900:00:29.369 outline clearance in working space in 00:00:31.40000:00:31.410 front and around both ends of the 00:00:33.17000:00:33.180 exchanger these working space should be 00:00:35.87000:00:35.880 kept clear of any piping and accessories 00:00:38.95900:00:38.969 to facilitate channel shall cover into 00:00:42.02000:00:42.030 bundle removal as well as maintenance 00:00:44.15000:00:44.160 and cleaning piping associated with heat 00:00:47.45000:00:47.460 exchangers should be routed as per 00:00:49.81900:00:49.829 general guidelines for layout you can 00:00:51.68000:00:51.690 refer our video the link is appearing on 00:00:53.93000:00:53.940 your screen moreover I'll link the video 00:00:56.27000:00:56.280 in the description box below the free 00:00:58.40000:00:58.410 space at the side of horizontal shell 00:01:00.41000:01:00.420 can be used for placement of control 00:01:02.75000:01:02.760 stations the piping is elevated from 00:01:05.69000:01:05.700 great to have a clearance of 300 mm from 00:01:08.39000:01:08.400 the grade level removable spools should 00:01:10.64000:01:10.650 be provided on the lines connected with 00:01:13.10000:01:13.110 the removable part of the exchangers for 00:01:15.26000:01:15.270 ease of maintenance locally mounted 00:01:18.32000:01:18.330 pressure and temperature indicators on 00:01:20.30000:01:20.310 exchanger nozzles on the shelf for 00:01:23.06000:01:23.070 channel lines should be visible from 00:01:25.01000:01:25.020 grade or access platform the steam lines 00:01:28.01000:01:28.020 connected to a header in the yard can be 00:01:30.38000:01:30.390 arranged on either side of the exchanger 00:01:32.21000:01:32.220 centerline without increasing the pipe 00:01:34.13000:01:34.140 length pulling water lines if 00:01:39.10900:01:39.119 underground should run right under the 00:01:41.24000:01:41.250 lined up channel nozzles of all coolers 00:01:45.58000:01:45.590 for stacked exchangers the nozzles 00:01:48.26000:01:48.270 between the exchangers shall be 00:01:50.30000:01:50.310 connected by exchanger vendor for other 00:01:52.70000:01:52.710 nozzles connected with external piping 00:01:55.13000:01:55.140 elbow nozzles can be proposed to reduce 00:01:56.99000:01:57.000 the height of the stack some of the 00:01:59.89900:01:59.909 typical piping arrangements are 00:02:01.53900:02:01.549 horizontal reboilers and for vertical 00:02:05.71900:02:05.729 tea boilers as you can see 00:02:07.61000:02:07.620 nice crease now let's talk about support 00:02:15.77000:02:15.780 location and the flexibility requirement 00:02:17.99000:02:18.000 for heat exchangers general points 00:02:20.39000:02:20.400 should be taken care of 00:02:22.01000:02:22.020 while deciding the support rotation 00:02:23.72000:02:23.730 angles play a large role in determining 00:02:25.88000:02:25.890 the piping configuration for exchanges 00:02:28.22000:02:28.230 it should be considered that in many 00:02:30.68000:02:30.690 cases the location of anchors can be 00:02:33.17000:02:33.180 adjusted to accommodate a better piping 00:02:35.24000:02:35.250 design this is applicable to both pipe 00:02:37.61000:02:37.620 anchors and exchange support anchors 00:02:39.83000:02:39.840 stress group recommendations should be 00:02:41.87000:02:41.880 followed to ensure minimum piping loads 00:02:44.36000:02:44.370 on nozzles of heat exchangers allow the 00:02:47.66000:02:47.670 muscle groups as well as standard margin 00:02:50.09000:02:50.100 roads of equipments allowable nozzle 00:02:52.28000:02:52.290 know it should be provided to mechanical 00:02:53.96000:02:53.970 Department at inquiry in position stage 00:02:56.27000:02:56.280 of air coolers piping supports on vendor 00:02:59.18000:02:59.190 provided structure should be avoided if 00:03:01.37000:03:01.380 any of the Clank specification mentions 00:03:04.43000:03:04.440 for free flange displacement criteria 00:03:06.50000:03:06.510 when supporting methodology shall be 00:03:08.93000:03:08.940 finalized accordingly ignition stage of 00:03:11.63000:03:11.640 project in setting vertical reboilers a 00:03:14.27000:03:14.280 number of options for method of support 00:03:16.64000:03:16.650 are possible as shown in the figure 00:03:18.14000:03:18.150 below the best place for any given 00:03:20.69000:03:20.700 application will depend on the process 00:03:23.24000:03:23.250 requirement as well as the availability 00:03:24.83000:03:24.840 of space type and weight of the 00:03:27.05000:03:27.060 equipments being used and the 00:03:28.97000:03:28.980 maintenance requirements for reboilers 00:03:32.69000:03:32.700 generally pipe supports at Challen tube 00:03:35.55000:03:35.560 exchanges can be incorporated with the 00:03:37.61900:03:37.629 exchanger support foundation and can be 00:03:40.02000:03:40.030 set up on the same foundation this can 00:03:42.60000:03:42.610 save the expense of separate support 00:03:44.30900:03:44.319 foundations anchors sat on such supports 00:03:48.05900:03:48.069 allow the pipe to grow with the 00:03:49.71000:03:49.720 exchanger instead of against it 00:03:51.42000:03:51.430 however stress recommendations project 00:03:54.56900:03:54.579 specification shall go on this criteria 00:03:57.58900:03:57.599 flexibility requirement for high 00:03:59.69900:03:59.709 temperature and high pressure lines as 00:04:02.49000:04:02.500 shown in the page there can be two 00:04:04.19900:04:04.209 arrangements possible to ensure 00:04:06.64900:04:06.65900:04:10.05000:04:10.060 pressure and temperature lines first is 00:04:12.59900:04:12.609 to provide loops in the piping layout as 00:04:14.72900:04:14.739 shown in alternative a and other is to 00:04:17.37000:04:17.380 provide spring support on the central 00:04:19.28900:04:19.299 exchanger as shown on the alternative B 00:04:21.52900:04:21.539 so that is it guys I hope you liked the 00:04:24.87000:04:24.880 video if you did please hit the like 00:04:27.00000:04:27.010 button for so more such useful
