Metal compensator is one of the products in pipeline installation. Its working principle is to use the scalability of metal bellows to reduce the problems caused by pipeline expansion and contraction. Metal compensator, also known as expansion joint and expansion joint, is mainly used to ensure pipeline operation. It is a flexible, thin-walled and transversely corrugated pipe fitting with elasticity. The metal compensator is composed of corrugated pipe (an elastic element), end pipe, support, flange, conduit and other accessories. It belongs to a compensation element. The operating principle of the metal compensator is mainly to use its own elasticity to compensate the axial, angular, lateral and combined displacement of the pipeline due to thermal deformation, mechanical deformation and various mechanical vibrations. The compensation effect has the functions of pressure resistance, sealing, corrosion resistance, temperature resistance, shock resistance, vibration reduction and noise reduction, which can reduce the pipeline deformation and improve the service life of the pipeline.
Metal compensator function:
1. Compensate the axial, transverse and angular cold and hot deformation of the absorption pipe.
2. The expansion and contraction of the corrugated compensator is convenient for the installation and removal of the valve pipe.
3. Absorb equipment vibration and reduce the impact of equipment vibration on pipeline.
4. Absorb the deformation of pipeline caused by subsidence.
Metal compensator can also be used for noise reduction and vibration reduction. It is widely used in modern industry. In terms of heat supply, in order to prevent the heat supply pipeline from heating up and causing pipeline deformation due to thermal elongation or temperature stress, it is necessary to set a compensator on the pipeline to compensate the thermal elongation of the pipeline, so as to reduce the stress on the pipe wall and the effect on the valve or support structure.
