Airtightness test
Thread Content
When performing a gas-tightness test on the device, can the pump be used as well?
Your device must be able to withstand the pressure generated by the pump; if a pump is to be used, this is something that must be ensured
Uh, if it’s a piping system, no pump is used during testing； After reset, perform a leak test.
There is no need for a pump, as the inlet and outlet pressures of the pump are different, and so are the pressures used for the airtightness test. If you’re not confident, you can do it separately.
