Hydrostatic testing of Heat Exchangers. 4 comments. Posted on May 24, 2001 by JIGNESH PATEL As per Mechanical Standards of TEMA, it is recommended that when tube test pressure is higher, Tube test shall be carried out, keeping the tube bundle outside the shell. This I suppose is to prevent shell exposure to high pressures beyond its design capacity in case of tube leak during tube test

Operation Procedures — Before placing any heat exchanger in operation, reference should be made to the exchanger drawing(s), specification sheet(s), and name plate(s) for any special instructions. Local safety and health regulations must be considered.
Shell side Hydrostatic Testing – After manufacturing completion, the heat exchange shell side will be subjected to the hydrostatic testing. The test pressure amount shall be consistent with the value indicated in the approved drawing. The holding time shall be based on the supplier approved test procedure.
Fallah , I have seen the hydrotest of this exchanger , this was after repetetive leaks in the tubes , the whole bundle got replaced , and after putting in the new bundle , before boxing up the channel cover the shell was pressurized to 1.5 times of tube design pressure to check whether the tubes leak or not .
SAFCO-INSPECTION DEPARTMENT. Heat Exchangers Hydrostatic Test Procedure Prepare the Exchangers for hydro test by providing necessary blinds and
Fill the heat exchanger with fresh water (less than 30 ppm chloride content) with a temperature of min 10ºC. Close the air venting valve when all the air is evacuated. Raise the pressure to correct test pressure according to the work order and/or general arrangement drawing and close the valve. During the time that the heat exchanger is under pressure, it is to be inspected for leakage
The hydro-testing procedure of a shell and tube heat exchanger requires you to fill the shell and tubing with water that had a color dye added to it. Then, raise the internal pressure by 1.5 times

The Heat Exchanger Training Program provides a step by step knowledge using sequential interactivity on the basic procedure involved in Heat Exchanger Assembly and Dismantling. The content covers the topic to component level detail.
The Third Party Inspection for Shell and Tube Heat Exchanger article provides a sample procedure for heat exchanger inspection and tsting. This procedure should be reviewed in conjunction with heat exchanger inspection and test plan.
A Procedures Manual was created for the double-pipe heat exchanger. The theories of transient heat transfer in double-pipe heat exchangers were explained and followed by literature correlations. All of the instrument specifications were defined. A procedure for use of the equipment and the software was outlined. Safety and other concerns during operation were discussed. This manual will serve
Steam heat in vertical shell and tube will have better heat transfer if the steam is in shell and thus smaller size heat exchanger while placing steam on shell would resulted to higher heat loss
