Air testing at 1 MpA should be used.

What needs to be pressure-tested is mainly to check the sealing performance

Pressure testing must be carried out to check the airtightness of the reinforcement ring

What needs to be pressure-tested is to check the sealing integrity of the gasket weld. Pressure testing uses 0. Compress air at 8 MPa is blown into the signal port to check for leaks at the fillet welds between the reinforcement ring and the shell, as well as at the fillet welds between the access pipe and the shell.
