00:00:00.000
hi guys welcome to our channel piping
00:00:02.540 00:00:02.550 mantra this is the continuation to part
00:00:04.849 00:00:04.859 1 of the previous video on heat
00:00:06.800 00:00:06.810 exchangers I will link this video in the
00:00:08.960 00:00:08.970 description box below and the link is
00:00:10.850 00:00:10.860 also appearing in suggestion box please
00:00:13.400 00:00:13.410 do watch so without further ado let's
00:00:16.099 00:00:16.109 get started on part 2 now comes the
00:00:19.130 00:00:19.140 question how can we establish the
00:00:20.720 00:00:20.730 elevation of exchangers the answer is
00:00:22.670 00:00:22.680 where process requirements dictate the
00:00:25.130 00:00:25.140 elevation it will be noted on the P&ID
00:00:27.140 00:00:27.150 and where the process requirements to no
00:00:29.330 00:00:29.340 dictate such elevation points some
00:00:31.490 00:00:31.500 general points can be considered for
00:00:33.680 00:00:33.690 setting up the elevation of heat
00:00:35.090 00:00:35.100 exchangers like from the economic point
00:00:37.819 00:00:37.829 of view great is the best location where
00:00:40.160 00:00:40.170 it is convenient for the tube bundle
00:00:41.900 00:00:41.910 handling maintenance and operation
00:00:44.540 00:00:44.550 wherever pni dimensions elevation of
00:00:46.729 00:00:46.739 heat exchanger as minimum for piping
00:00:49.180 00:00:49.190 exchanger should be elevated to ensure
00:00:51.590 00:00:51.600 sufficient clearance below the piping
00:00:53.900 00:00:53.910 connected to the biggest knob the figure
00:00:55.610 00:00:55.620 shows the typical heat exchanger
00:00:57.260 00:00:57.270 elevation setup clear distance between
00:00:59.119 00:00:59.129 the blind-date or plug drain in this
00:01:01.849 00:01:01.859 line should be asked for piping design
00:01:04.009 00:01:04.019 standard however project specification
00:01:06.410 00:01:06.420 shall go on this clarence it can be
00:01:09.350 00:01:09.360 optimized by using elbow nozzle instead
00:01:11.899 00:01:11.909 of a straight nozzle as shown in the
00:01:14.210 00:01:14.220 figure however clearance from platform
00:01:16.700 00:01:16.710 should be consider in case of process
00:01:20.420 00:01:20.430 requirement usually exchangers can be
00:01:22.609 00:01:22.619 located in structures when gravity flow
00:01:25.340 00:01:25.350 is required to the collecting drum or
00:01:27.260 00:01:27.270 where the outlet is connected to a pump
00:01:30.469 00:01:30.479 suction which has specific and PSS
00:01:32.690 00:01:32.700 requirements as specified in pni for
00:01:35.090 00:01:35.100 kettle type exchangers when connected
00:01:36.920 00:01:36.930 with columns the required elevation is
00:01:38.929 00:01:38.939 normally specified in the pn ids or
00:01:40.999 00:01:41.009 process data sheets based on the
00:01:43.010 00:01:43.020 relative elevation of column nozzle and
00:01:45.109 00:01:45.119 kettle type exchanger internals
00:01:47.300 00:01:47.310 now the general points which should be
00:01:49.190 00:01:49.200 taken care of while deciding no
00:01:50.899 00:01:50.909 certifications are avoid zigzag flow
00:01:53.480 00:01:53.490 pattern as shown in the figure
00:01:55.929 00:01:55.939 relocation of shell side and tube side
00:01:58.880 00:01:58.890 nozzles can be requested in extreme
00:02:00.800 00:02:00.810 cases only if it results into
00:02:02.840 00:02:02.850 considerable cost savings bottom nozzle
00:02:06.350 00:02:06.360 near to the saddles of
00:02:07.819 00:02:07.829 and it's connected piping should be
00:02:09.619 00:02:09.629 checked for possible fouling with the
00:02:11.330 00:02:11.340 saddle suppose our exchanger Foundation
00:02:13.280 00:02:13.290 and solution on my opinion exchangers
00:02:16.070 00:02:16.080 should be taken into account while
00:02:17.720 00:02:17.730 deciding the protection of nozzles
00:02:20.199 00:02:20.209 orientation of the reboiler nozzle on
00:02:22.670 00:02:22.680 the column should be planned to have
00:02:24.770 00:02:24.780 sufficient flexibility with minimum
00:02:26.809 00:02:26.819 bends in the line connected between
00:02:28.820 00:02:28.830 reboiler and column in case David is
00:02:31.910 00:02:31.920 provided at the end of exchanger for
00:02:33.830 00:02:33.840 opening of the cover the location and
00:02:36.440 00:02:36.450 orientation should be provided to
00:02:38.360 00:02:38.370 mechanical to avoid fouling with any
00:02:41.000 00:02:41.010 nearby facilities when opening of the
00:02:43.400 00:02:43.410 cover the opening volume required for
00:02:45.800 00:02:45.810 the end cover should be blocked in the
00:02:47.750 00:02:47.760 model to avoid any interference
00:02:49.610 00:02:49.620 now let's talk about access for
00:02:51.800 00:02:51.810 operation and maintenance internals of
00:02:53.780 00:02:53.790 heat exchangers require periodic
00:02:56.150 00:02:56.160 cleaning in repair it is important that
00:02:58.550 00:02:58.560 exchangers and the surrounding piping
00:03:00.890 00:03:00.900 are arranged to facilitate access to the
00:03:03.710 00:03:03.720 internal parts horizontal clearance of
00:03:06.410 00:03:06.420 at least 600 mm should be left between
00:03:08.839 00:03:08.849 the exchangers flange to flange or
00:03:11.240 00:03:11.250 exchanger flanges to piping where space
00:03:13.580 00:03:13.590 is limited clearance may be reduced
00:03:15.379 00:03:15.389 between alternate exchangers but in no
00:03:17.900 00:03:17.910 case clearance over insulation between
00:03:20.059 00:03:20.069 channel and flanges shall be less than
00:03:21.920 00:03:21.930 600 mm the first picture shows the
00:03:24.259 00:03:24.269 arrangement of exchangers with two feet
00:03:26.539 00:03:26.549 to 6 inches operating space between
00:03:28.789 00:03:28.799 piping the second picture shows the
00:03:31.009 00:03:31.019 00:03:33.199 00:03:33.209 maintaining space between pair units and
00:03:35.509 00:03:35.519 two for six inches space between piping
00:03:38.449 00:03:38.459 exchanges should have piping routed with
00:03:40.759 00:03:40.769 the view towards maximizes access to the
00:03:43.819 00:03:43.829 two bundle and other maintainable
00:03:45.740 00:03:45.750 component the removal space should be
00:03:47.660 00:03:47.670 reserved in the model common axis the
00:03:50.059 00:03:50.069 channel ends of exchanger should face
00:03:52.370 00:03:52.380 the local access rule for to bundle
00:03:54.470 00:03:54.480 removal and the shell cover should face
00:03:56.870 00:03:56.880 the pipe line pulled out bundle should
00:03:59.569 00:03:59.579 not extend over main access rule with
00:04:01.819 00:04:01.829 the exchangers that have no removable
00:04:03.710 00:04:03.720 serviceable components suitable
00:04:05.599 00:04:05.609 arrangement and clear space on top for
00:04:08.360 00:04:08.370 removing the entire exchanger can be
00:04:10.220 00:04:10.230 provided access for to bundle removal is
00:04:12.800 00:04:12.810 usually 500 and
00:04:14.199 00:04:14.209 more than the bottle a wine equipment
00:04:16.749 00:04:16.759 should be used for handling two bundles
00:04:18.699 00:04:18.709 and covers at grade level expensive
00:04:21.279 00:04:21.289 building facilities for example lifting
00:04:23.350 00:04:23.360 beams or mono rails to be kept at menu
00:04:25.840 00:04:25.850 the use of tube bundle extractor
00:04:27.939 00:04:27.949 eliminates the need for permanent tube
00:04:30.010 00:04:30.020 bundle removal structures these machine
00:04:32.260 00:04:32.270 mechanism way around seven tons and are
00:04:34.719 00:04:34.729 capable to cool force is about 500,000
00:04:37.300 00:04:37.310 lbs the tube bundle is held in position
00:04:39.969 00:04:39.979 by crane and balanced by the extractors
00:04:42.460 00:04:42.470 leveling cradle and pulled out of its
00:04:44.590 00:04:44.600 shell with pull rod attachments that has
00:04:47.020 00:04:47.030 hydraulic force provision of easily
00:04:49.540 00:04:49.550 removable spool pieces plans elbows peg
00:04:52.629 00:04:52.639 flanges and short pipe runs will be
00:04:55.089 00:04:55.099 helpful for maintenance of exchangers so
00:04:58.839 00:04:58.849 that is it guys will continue this part
00:05:01.779 00:05:01.789 two in further part 3 so do watch that I
