Leakage testing is an important quality-control step for shell-and-tube heat exchangers. The workshop photo shows an exposed tubesheet, tube ends, a bolted flange and a connected pressure gauge, providing a close view of the exchanger during inspection.

Testing helps identify leaks in tubes and tube-to-tubesheet joints that could allow the shell-side and tube-side fluids to mix. Depending on the test arrangement, inspection also covers accessible sealing connections. Gauge readings are assessed alongside the observations required by the selected leak-detection method.

The test medium, pressure, holding time and acceptance criteria should follow the approved procedure for the specific exchanger. Inspection records document the test conditions and findings. Any detected leakage requires evaluation, correction and repeat testing before acceptance.

For a customized Vrcoolertech shell-and-tube heat exchanger, provide the heat duty, working fluids, design pressures and temperatures, connection requirements and inspection scope. These details help define the equipment design and the testing documentation required for the project.
