Thread Content
When performing a hydrostatic test on a jacketed vessel, under what conditions does the inner vessel need to be pressurized, to what pressure, and which standards specify this? Does anyone among the experts know?
According to the design specifications, if pressure retention is required, it shall be indicated in the drawings; if not specified, the inner cylinder does not need to be pressurized during the hydraulic test of the jacket.
Calculate it using SW6; the calculation sheet will provide guidance
