1、 Gas shielded welding

Under gas protection, the chromium and nickel on the surface of stainless steel will not be oxidized during welding, retaining the original characteristics and corrosion resistance of stainless steel

The characteristics of erosion.

2、 Bright solid solution

After the stainless steel pipe fittings are formed and welded, they must undergo a solution treatment at 1050 ℃ to eliminate the deformation caused by the pipe fittings

By reducing internal stress and reducing stress corrosion, it can restore intergranular changes during the welding process of pipe fittings and dissolve carbides in the welding heat sensitive zone

Dissolve in austenite to prevent adverse effects on the performance of austenitic stainless steel.

3、 Pickling passivation

Acid pickling and passivation can produce a thin, dense, and hard passivation film on the inner and outer walls of water pipes and fittings. The existence of the passivation film is rust free

The root cause of steel corrosion prevention.

4、 Sealing material

The sealing material is the lifeline of stainless steel pipelines, and the service life of the sealing material determines the service life of stainless steel pipelines.

The sealing ring we provide is made of imported rubber, and the physical properties of the material are much higher than those of domestic rubber.
