Metal Expansion Joint Stainless steel Flexible Joint with Flange
Metal expansion, also known as expansion joint, expansion joint, is mainly to ensure the safe operation of the pipeline. Metal expansion is a flexible thin-walled transverse bellows device with expansion function, which is composed of metal bellows and components. The principle of metal expansion 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. The metal expansion has the functions of pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration reduction and noise reduction. The metal expansion can reduce the deformation of the pipeline and improve the service life of the pipeline.
Performance of metal expansion
1. The metal expansion has good compensation
2. The metal expansion can withstand high temperature
3. Metal expansions can reduce leakage
4. Vibration resistance and high-speed performance of metal expansion
5. The metal expansion can reduce the specific pressure of the spring
6. Possible torque transmission of metal expansion
7. The metal expansion can reduce the seal failure caused by scale through certain structural design
