Metal bellows is a kind of pipe with regular wave-like appearance. Commonly used metal bellows are carbon steel, stainless steel, steel lined with plastic, aluminum, etc. It is used primarily for non-concentric axial transmission with a small bending radius, irregular turning, expansion, or absorption of thermal deformation of pipes, or for connecting pipes to pipes or pipes to equipment when it is not convenient to install with fixed elbows.

- Features of metal bellows

1) Balance and compensation to prevent displacement or vibration under extreme temperature, pressure, or thrust.

2) Widely used in various aspects of the high-tech steel industry and other industries.

3) They are flexible and can handle extreme temperatures and pressures well.

4) They play an important role in the reciprocating motion of the hose, absorbing thermal expansion, absorbing vibrations, and adjusting the center of the composite pipe.
