Flange Bellow Epansion Joint

bellow expansion joint

The bellows compensator is a special flexible compensation fitting for pipeline systems. Its function is to absorb axial and lateral displacements and angular deviations caused by pipeline thermal expansion and contraction, equipment vibration, etc., relieve pipeline thermal stress, prevent pipeline damage, and realize sealed medium transportation. Its structure includes stainless steel bellows, flange joints, etc., with flexible compensation and sealing reliability. It is widely used in various industries, suitable for various media and complex working conditions.

The core corrugated pipe is made of high-quality stainless steel integrated molding, which has corrosion resistance, high temperature resistance, and deformation resistance. The flange connection adopts standardized design for easy docking. Guidance and limit devices ensure safe use, special seals ensure no leakage under high pressure, reasonable structure, and long service life.
