Product features:

1.Resistance to high pressure

Considering the actual working pressure bellows,After all the parameters of careful calculation and trial and error, ensure their pressure in work safety.

2.Do manual work is delicate

The appearance is very bright, permanent if brightness is new.

3.High corrosion resistance

The body of the bellows is made of 304 or 316L stainless steel, both ends of stainless steel or carbon steel joint, it has good corrosion resistance, to ensure the sealing.

4.Convenient for installation

The overall weight is lighter, greatly reduces the load of construction work and construction time.

5.Shock proof dislocation

Stainless steel bellows has good flexibility and compensation displacement characteristics
