Problems with the size of the socket welding end of socket welding valves
Thread Content
Socket welding valves, such as Z61H-40 DN15, use metric pipes. The outer diameter of the pipe is 18mm. According to the socket welding connection and pipe end size JB/T1751-92, the socket welding end size of the socket welding valve is 22.5mm. Can it be welded?
It can also be welded, that is, the gap between the pipe and the valve is slightly about 3mm, and multi-layer and multi-pass welding can be used during welding.
