I’d like to ask gently: are pressure pipeline components such as elbows and tees manufactured by factories subjected to pressure tests before leaving the factory?

Check the corresponding standard requirements and business requirements!
:lol:lol 99.9955645% will not perform the voltage test. . .
It’s too troublesome to do, so most manufacturers don’t do it
Specific products are not manufactured, but type tests must be carried out in accordance with the specified requirements.
This morning, I checked the **standards** for steel butt-welded pipe fittings and steel plate butt-welded pipe fittings; no pressure testing is required before the products leave the factory.
It’s definitely impossible to do them one by one; was it done in accordance with the requirements for inspection batches? ? ?
Article 7.6 of GBT 13401-2017 \"Technical Specifications for Welded Steel Fittings\" provides detailed explanations in the section on inspection and testing
