The axial external pressure bellows mainly absorbs axial displacement and has the advantages of large compensation, good thermal insulation performance, and the elimination of residual media. The axial internal pressure bellows compensator is composed of a bellows (an elastic element) that constitutes its working body and accessories such as end tubes, brackets, flanges, and conduits. Belongs to a compensation component. It utilizes the effective expansion and contraction deformation of the corrugated pipe of its working body to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, or to compensate for the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used to reduce noise and vibration. It is widely used in modern industry. Corrugated compensator connection methods: divided into two types: flange connection and welding. Directly buried pipeline compensators generally use welding (except for trench installation).
The axial external pressure bellows steam pipeline expansion joint mainly absorbs axial displacement, and has the advantages of large compensation, good thermal insulation performance, and the elimination of residual media. Bellows mainly include metal bellows, corrugated expansion joints, corrugated heat exchange tubes, diaphragm capsules and metal hoses. Metal corrugated pipes are mainly used to compensate for thermal deformation of pipelines, absorb shock, and absorb pipeline settlement deformation. They are widely used in petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy and other industries. Corrugated pipes made of plastic and other materials play an irreplaceable role in media transportation, power wiring, machine tools, home appliances and other fields.
The axial external pressure compensator (axial external pressure expansion joint) consists of one or more bellows connected in series through an intermediate pipe. After the two ends are welded to the inner sealing plate and the bottom sealing plate respectively, they are then connected to the through pipe respectively. The outer tubes of the tube are connected, and the corrugated tube has a higher number of waves.
