Can the socket be connected directly?
Thread Content
Is there a problem with the pressure gauge on the large pipeline, where the root valve is directly connected to the short pipe branch platform SW?
It’s rare; generally, the valves are of the SW type.
What is the diameter? ? It seems fine when looked at
What do the ports of the valve look like? With a section of straight pipe? With socket welding, it’s not possible to connect them. How do I replace a valve if it is leaking? The branch fitting is of SW type; a short pipe, about 100 mm long, will be added, and the socket weld joint of the valve is then welded to this short pipe. In the future, when the valve needs to be replaced, the short pipe can also be cut a little shorter.
It’s rare; the PID chart seems to indicate no problems
What kind of connection is a root valve, exactly?
If the valve is socket-welded, it cannot be welded to a socket-type branch fitting; and if it is a valve with a flange at its base, it is even less possible to connect it.
If the valves are socket-welded, they cannot be connected directly; a straight pipe section needs to be added
The valve is either equipped with flanges; in that case, the branch pipe fitting is welded to a flange, which is a waste – if it gets damaged, then that flange is also wasted. If socket welding is used, the branch pipe fitting cannot be welded on, and a short pipe section is required
