Stainless steel metal bellows expansion joint
The metal bellows expansion joint also known as bellows compensator, flange expansion joint, flexible expansion joint, etc. it is a compensation element, expansion joints are installed in a piping system to absorb vibration and shock. They also have advantages such as reducing the noise and compensate caused by misalignment.
Natural compensation is the most economical method in pipeline compensation design. Natural compensation is flexible methods by the use of the natural bending of the pipeline to compensate the thermal displacement, which is limited, when the natural compensation can not meet the requirements, metal bellows expansion joints and other compensation devices can be used. A load of the pipeline is mainly external load (pipeline and liquid medium weight, internal pressure, wind and earthquake load, etc.) and displacement load, the expansion joint can eliminate the external load on equipment or pipeline, it can divide the complicated piping system into single and independent section to ensure the best use of expansion joint effect. The pipeline expansion joint can compensate the axial, transverse and angular thermal deformation, absorb the vibration of the equipment and deformation of the pipeline caused by earthquake and subsidence, reduce the impact of the vibration of the equipment on the pipeline. The bellows expansion joint is used in cold and hot pipeline systems, iron and steelworks, thermal power plants, smoke exhaust desulfurization, dust removal equipment, air heating, flow aid blast and another equipment outlet.
