Question

Accepted Answer

To check hydro test on a heat exchanger, perform visual inspection, pressure testing, and leak testing.

Perform a visual inspection of the heat exchanger for any visible damages or defects.
Conduct a pressure test by filling the heat exchanger with water or another suitable test medium and gradually increasing the pressure to the specified test pressure.
Monitor the pressure for a specified duration to ensure it remains stable without any significant drop.
Perform leak testing by applying a suitable leak detection method such as soap solution or helium leak testing.
Inspect for any leaks and repair if necessary before retesting.
Document the test results and ensure compliance with applicable codes and standards.
