What is the standard temperature of the weld after welding that is required before conducting a hydrostatic test? (Urgent)
Thread Content
What temperature standard must the weld reach after welding before a hydrostatic test can be conducted? Are there specific standard regulations? Could some expert please give me some guidance?
This question is a bit unclear; the temperature of the weld after welding needs to be reduced to room temperature before testing can be carried out. And it’s impossible to weld the entire pipeline at once and finish welding it all in one go
2# Kuanhai is not a pipeline as a whole, but rather an individual valve. After a set of valves is welded together, a hydrostatic test must be carried out. I’m not sure where such standards can be found; I’d like to learn more about this
