Product Description

Stainless steel bellows compensator, also known as stainless steel bellows expansion joint, is a flexible, thin-walled, transverse corrugated device with expansion function, which is composed of metal bellows and components. The working principle of bellows compensator 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 compensation function has the functions of pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration reduction and noise reduction, which can reduce the pipeline deformation and improve the service life of the pipeline.
Stainless steel bellows compensator, as a sensing element, damping element, compensation element, sealing element, valve element and pipeline connector, is widely used in automatic control and measuring instruments, vacuum technology, machinery industry, power industry, transportation, atomic energy industry and other fields.
The main elastic element of the stainless steel corrugated compensator is the stainless steel corrugated pipe, which is used for axial, transverse and angular compensation of the pipeline by expansion and bending of the corrugated pipe. Its function can be:
1. Compensate the axial, transverse and angular thermal deformation of the absorption pipe.
2. Absorb equipment vibration and reduce the impact of equipment vibration on pipeline.
3. Absorb the deformation of pipeline caused by earthquake and ground subsidence.
The compensator can be divided into unrestricted bellows compensator and constrained compensator according to whether it can absorb the pressure thrust (blind plate force) generated by the medium pressure in the pipeline; According to the displacement type of bellows, it can be divided into axial type compensator, transverse type compensator, angular type compensator and pressure balance type bellows compensator.
