1. Gas shielded welding: Under gas protection, the chromium and nickel on the surface of stainless steel will not be oxidized during welding, and the original characteristics and corrosion resistance of stainless steel are preserved;
2. Pickling passivation: Pickling passivation can produce a thin, dense and hard passivation film on the inner and outer walls of stainless steel pipe fittings. The existence of the passivation film is the basis for preventing corrosion of stainless steel pipe fittings;
3. Sealing material: The sealing material is the ring node of the application life of stainless steel pipe fittings, and the application life of the sealing material determines its application life. Our stainless steel pipe fittings use imported chlorinated butyl sealing ring, and the physical function of the material is much higher than that of domestic rubber;
4. Bright solid solution: After the stainless steel pipe fittings are formed and welded, they must undergo a 1050 degree solid solution treatment to eliminate the internal stress caused by the deformation of the stainless steel pipe fittings, reduce stress corrosion, and restore the intercrystalline changes during the pipe fitting welding process. , Dissolve the carbides in the welding heat-sensitive zone in the austenite to prevent the adverse effects on the performance of austenitic stainless steel
