Pipeline pressure testing issues
Thread Content
For example, the operating pressure of an industrial pipeline is 1.0 Mpa, the design pressure is 1.1 Mpa, and the set pressure of the safety valve is also 1.1 Mpa. The hydrostatic test pressure is 1.65 Mpa; won’t this cause the safety valve to activate? Should the safety valve be removed during the pressure test as well? Seeking advice
During pressure testing, the safety valve should be removed; it is designed for normal operating conditions, not for pressure testing conditions
The safety valve does not need to be installed during the hydrostatic test; otherwise, the test cannot be carried out
