Stainless steel bellows compensator flanged expansion joint
Flanged expansion joint, also known as expansion joint, flanged expansion joint is composed of metal bellows and components, mainly to ensure the safe operation of the pipeline. Flanged expansion joint is a flexible thin-walled transverse bellows device with expansion function,. The principle of flanged expansion joint is to use its elastic expansion function to compensate the axial displacement, angular displacement, lateral displacement and combined displacement caused by thermal deformation, mechanical deformation and various mechanical vibration. Flanged expansion joints have the functions of pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration and noise reduction. The flanged expansion joint can reduce the deformation of the pipeline and improve the service life of the pipeline.
Performance of flanged expansion joint
1. The flanged expansion joint has good compensation
2. The flanged expansion joint can withstand high temperature
3. Flanged expansion joint can reduce leakage
4. Vibration resistance and high-speed performance of flanged expansion joint
5. The flanged expansion joint can reduce the specific pressure of the spring
6. Possible torque transmission of flanged expansion joint
7. The flanged expansion joint can reduce the seal failure caused by scale through certain structural design
