For a solvent tank with nitrogen sealing, designed at a pressure of 0.08 MPa, what should be the pressure used for testing? Is a gas-tightness test still needed?
The design pressure is too low, so no pressure strength test is required. The wall thickness of such equipment is generally determined based on the standards for equipment operating at normal pressure; however, to ensure the overall rigidity of the equipment, the wall thickness is always sufficient to meet the strength requirements. Since the equipment needs to be sealed with nitrogen, a gas seal test must be conducted.
The design pressure is 0.08 MPA, gauge pressure; is it a vacuum tank?
There is no such thing as absolute pressure design; it’s all gauge pressure.
With such a low design pressure, it’s sufficient to conduct a water filling test; there’s no need for pressure testing as it poses risks
It is not a pressure vessel, so pressure testing is not required. Just do a leak test with clean water
