Pressure test on in-use pressure vessels and airtightness test of pressure vessels
Thread Content
What is the difference between the pressure test for pressure vessels in use and the airtightness test for pressure vessels? ? ? ?
I think the testing medium is different, as is the pressure used; it’s just my personal opinion.
Pressure resistance is a strength test, while airtightness is a sealing test; their purposes in verification are different.
Different test pressures result in different pressure testing methods, as well as different purposes for such testing. The hydraulic test is a strength verification, while the airtightness test is a check for tightness
The pressure, methods, and purposes are all different
