The use of stainless steel pipe fittings range is wide, all can use in industrial and civil. And choose the stand or fall of its own material when the stainless steel pipe fittings will has certain influence to the application, and for some special industries, such as nuclear power, petrochemical industry, medical and other industries of stainless steel pipe fittings quality requirement is high. And one of the gas shielded welding is very important for the implementation of the stainless steel pipe fittings.
A, gas shielded welding; When welding on the surface of the gas under the protection of stainless steel, chromium and nickel not happen chemical reaction, can guarantee the original quality and corrosion resistance of stainless steel;
2, pickling passivation: can make the outer wall of pipes and pipe fittings with a layer of thin and thick, hard passivation membrane, is to prevent the root cause of the corrosion occurred;
Three, light solid fusion: stainless steel pipe after forming, welding process, must through 1050 degrees solid fusion processing, is used to eliminate the stainless steel pipe fittings for deformation and internal stress, reduce stress corrosion, the pipe welding in the process of restoration, intercrystalline change carbide dissolution in austenite, prevent adverse effect;
Four, sealing material, sealing material is a key point of the service life of the stainless steel pipe, the service life of sealing material decides the service life of the stainless steel pipe.
