It depends on the process requirements; it cannot be generalized.
Some have water pressure, some have air pressure... depending on the process
Generally, yes. For the pipes used in home renovations, a pressure test must be conducted before use to check for leaks.
After the piping installation is completed, and heat treatment and non-destructive testing are successful, a pressure test should be carried out. It is divided into hydraulic and pneumatic tests. In cases where on-site conditions do not permit hydraulic and pneumatic testing of the pipelines, with the consent of the construction party and the design party, non-destructive testing, flexible analysis of the pipeline system, and leakage testing may be used as alternatives to pressure testing, provided that such methods comply with relevant regulations. Refer to GB50184-2011

I’m also struggling with this. For ordinary exhaust pipes, the diameter is large and the pressure is very low, only a few thousand pascals – does such a pipe also need to undergo a pressure test? Especially when it comes to gas pipelines that are one meter in diameter, will the hydrostatic test load be too high?
