Stainless steel pipe fittings are widely used in both industrial and civilian applications. The choice of stainless steel pipe fittings when the quality of their own materials will affect its application, and some special industries such as petrochemical, nuclear, medical and other industries on the quality requirements of stainless steel pipe fittings higher.
First, the gas protection welding in the welding of the gas under the protection of stainless steel surface of chromium and nickel will not be oxidized, retain the original characteristics of stainless steel and corrosion resistance;
Second, pickling passivation: can make the water pipe and pipe wall to produce a thin and dense, hard passivation film, is to prevent the root causes of corrosion;
Third, the bright solidification: stainless steel pipe after forming, welding process, must be 1050 degrees of solid solution to eliminate the stainless steel tube due to deformation caused by internal stress, reduce stress corrosion, recovery pipe welding process of intergranular changes, Carbide dissolved in austenite, to prevent adverse effects;
Fourth, the sealing material: sealing material is the key point of the life of stainless steel pipe, sealing material life determines the life of stainless steel pipe fitting.
