Welding Methods And Advantages Of Stainless Steel Pipe Fittings

There is no sealing ring inside, which is a dead joint. Both surface and concealed installation are acceptable. They are applicable to both cold water system and hot water system. After installation, maintenance is basically unnecessary. This kind of connection has been used on copper pipes for many years, and the Ministry of Construction now also focuses on the jointless connection of stainless steel.
The main difference between the quality of stainless steel pipe fittings is the content of nickel. Nickel is an excellent corrosion resistant material. The combination of nickel and chromium in stainless steel can improve the corrosion resistance and process performance of stainless steel. However, in order to obtain pure austenitic structure, the nickel content of nickel steel should reach 24%, and only when the nickel content is 27% can the corrosion resistance of steel in some media be significantly changed.
