Heat exchanger airtightness
Thread Content
U-type heat exchanger, with a shell-side operating pressure of 16.2 MPa and an operating temperature of 260 degrees; the fluid involved is hydrogen and hydrogen sulfide； The working pressure of the tube train is 18.6 MPa, the working temperature is 71 degrees, and the medium is hydrogen. I would like to ask the experts: is it necessary to perform a hydrogen gas tightness test on this heat exchanger?

This is essentially playing it by the rules in a subtle way: some standards require extremely high levels of performance with no allowance for any leakage, while others also stipulate that materials with strong permeability must be used as well. It depends on how you choose to comply.
