Metal bellows with its flexibility to compensate for the piping system due to the installation of the positional deviation and meet the requirements of the working end of the displacement in all directions, and withstand the fluid pressure of the system. Metal bellows in many important industrial areas in the role of irreplaceable, which puts forward a high demand for its quality, so understand its role at the same time, the use of different metal materials should be selected to improve the quality of its role to play a large number of.
The planar stability, circumferential stability and corrosion resistance of corrugated compensators are all related to their displacement, i.e. fatigue life.It solves the problem of pipe bursting and damage to pipeline connecting equipments due to thermal expansion and contraction with its unique design, novel structure and good sealing performance.
