Metal Bellow Expansion Joint for Pipe
Expansion joint for pipe, also known as expansion joint, expansion joint, is mainly to ensure the safe operation of the pipeline. Expansion joint for pipe is a flexible thin-walled transverse bellows device with expansion function, which is composed of metal bellows and components. The principle of expansion joint for pipe 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 expansion joint for pipe has the functions of pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration reduction and noise reduction. The expansion joint for pipe can reduce the deformation of the pipeline and improve the service life of the pipeline.
Performance of expansion joint for pipe
The main elastic element of expansion joint for pipe is stainless steel bellows. Through the expansion and bending of bellows, the expansion joint for pipe compensates the pipeline in axial, transverse and angular directions. Metal bellows can play the following roles:
1. The expansion joint for pipe absorbs the axial, transverse and angular thermal deformation of the pipeline.
2. Expansion joint for pipe can absorb equipment vibration and reduce the influence of equipment vibration on pipeline.
3. Expansion joint for pipe can absorb the pipeline deformation caused by earthquake and land subsidence.
