The 304 stainless steel bellows expansion joint consists of a metal bellows and a member. It is a flexible, thin-walled, laterally corrugated, telescopic device.
The working principle of the bellows expansion joint is mainly to use its own elastic deformation function to compensate the axial, angular, lateral and combined displacement of the pipeline due to thermal deformation, mechanical deformation and various mechanical vibrations. The compensating function has the functions of pressure resistance, sealing, corrosion resistance, temperature resistant, shock resistance, vibration and noise reduction. It can reduce the deformation of pipeline and improve the service life of pipeline.
light weight, simple structure, convenient installation and maintenance, large compensation
