Stainless steel water pipe There are several different connection methods:

For welded connection valves, when the nominal diameter is large, the service conditions are engraved, and the temperature is high, the valve body often adopts groove butt welding. At the same time, there are original requirements for the welding seam, and skilled welders need to be selected to complete this work. Welded valves with nominal diameter less than 50 mm usually have welding sockets to undertake the pipeline at the load plane end, Since socket welding forms a gap between the socket and the pipe, it may cause the gap to be corroded by some media, and the vibration of the pipe will fatigue the connection part, so the use of socket welding is limited.

The threaded valves are mainly those with nominal diameter less than 50 mm. If the size of the diameter is too large, it is very difficult to install and seal the connection part. The threaded connection is usually to process the inlet and outlet ends of the valve into taper pipe or straight pipe threads, which can be connected to taper pipe threaded joints or pipelines.

Flange connected valves are easy to install and disassemble, but the flange connection is heavier than the threaded connection, and the corresponding price is also high. Therefore, it is suitable for the connection of pipes with various diameters and pressures. When the temperature exceeds 350 degrees, the load of bolts will be significantly reduced due to the relaxation of bolts, gaskets and flanges, Leakage may occur to the flange connection under great stress.
