Description

Metallic expansion Bellows is a flexible, thin-walled, transversely corrugated, retractable device consisting of a metal bellows and components. The working principle of the Metallic expansion Bellows is mainly to use its own elastic expansion function to compensate the axial, angular, lateral and combined displacement of the pipeline due to thermal deformation, mechanical deformation and various mechanical vibrations. Pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration and noise reduction, reduce pipe deformation, improve the service life of the pipe
