Are pipe fittings such as pipes, elbows, and tees pressurized before leaving the factory? What about the valve? If suppression is to be carried out, what is the proportion of suppression? Is it random testing or full testing?

Are pipe fittings such as elbows and tees pressurized before leaving the factory? What about the valve? If suppression is to be carried out, what is the proportion of suppression? Is it random testing or full testing? Are there any relevant standards or specifications that set rules regarding the manufacturing and release of pipe fittings in this regard?
For valves, you can refer to GB/T 13927
For valves, it’s 1.5 times the safety test level
Fittings – definitely not every time under pressure; high-pressure valves should be tested
