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 for work safety.
2. Manual work is delicate
The appearance is very bright and permanent if the brightness is new.
3. High corrosion resistance
The body of the bellows is made of 304 or 316L stainless steel, with both ends of stainless steel or carbon steel joints. It has good corrosion resistance to ensure the sealing.
4. Convenient for installation
The overall weight is lighter, which greatly reduces the load of construction work and construction time.
5. Shock-proof dislocation
Stainless steel bellows has good flexibility and compensation displacement characteristics
