Pipe connections using threads and socket welding
Thread Content
For pipes connected by socket welding or threading, are pipe clamps necessary? At what interval should they be installed?
Why is it necessary? Nothing is necessary, right?
For socket weld connections or NPT connections, welding is not possible; in such cases, clamping connections should be used. The additional length depends on the processing length of the pipes; it’s the same as the length of each pipe when it arrives at the site. Generally, it’s about six meters per piece
For socket welding, it is generally used for diameters below DN40, and no pipe clamps are required. For threaded pipes such as galvanized pipes used for clean air handling, pipe clamps seem to be needed every 6 meters
Pipe clamps are used to connect pipe sections; if not, should welding be used? Then it fails to meet the requirements for socket welding and threading. I understand what the original poster is asking: regarding couplings/union fittings, especially for longer pipe sections – those several dozen meters long – where the threads are tightened in a clockwise direction, what should be done when it comes to the last fitting, which requires tightening in a counter-clockwise direction? Then Union is needed. When setting it up, consider the ease of disassembly on site – the fewer components, the better.
Check my reply on floor 5. I received another award; WeChat notified me that there was a reward. :lol
I saw it, but I’m not online at night
It’s not necessary. Use it only where a connection is needed. The less, the better.
I asked at the construction site; actually, many of the pipelines are welded directly without using pipe collars
It’s not necessary; it depends on the actual situation as well. You can also take a look at the answers given by other friends upstairs
