< )The bellows compensator is composed of metal bellows and components. The working principle of the bellows compensator is mainly to use its own elastic expansion and contraction function to compensate for the axial, angular, lateral and combined displacements of the pipeline caused by thermal deformation, mechanical deformation and various mechanical vibrations. The compensation function has the function of pressure-resistant sealing. Corrosion resistance, temperature resistance, impact resistance, vibration damping and noise reduction functions can reduce pipeline deformation and increase pipeline service life.
<) The design, manufacturing, installation and operation management of metal bellows compensators are composed of multiple links. Therefore reliability should also be considered from several aspects. When selecting the material used in the corrugated pipe in the heating pipe network, in addition to its working efficiency, its medium working temperature and external environment should also be considered. We must also take into account the possibility of stress corrosion, water treatment agents, and cleaning of the pipes. Influence of materials, and on this basis, with bellows materials, welding, forming, material cost and performance, points out the material's economic and practical production optimization of bellows.
< )Under normal circumstances, the material used for metal bellows compensator should meet the following conditions:
< )) High elastic limit, tensile strength and fatigue strength, and Make sure the bellows is working.
< )) Good plasticity to facilitate compensator molding and processing, and to obtain sufficient hardness and strength through subsequent processing (work hardening, heat treatment, etc.).
< )) Good corrosion resistance to meet the requirements of bellows working in different environments.
< )) Good welding performance to meet the welding process requirements during the production of bellows.
< ) Application of bellows compensator:
< ) Pipes with large deformation and limited spatial position.
< ) Large-diameter pipes with large deformation and displacement and low working pressure.
< ) Need to limit the equipment taking over the load.
< )Pipelines required to absorb or isolate high-frequency mechanical vibrations.
< ) Pipes required to absorb earthquakes or foundation settlement.
< )Absorbs the vibration at the pipeline pump outlet.
