Corrugated compensator belongs to a compensation element. It is composed of bellows (an elastic element) and end pipes, brackets, flanges, conduits and other accessories that constitute the main body of its work. Using the effective expansion and contraction deformation of its working body bellows, to absorb the size change of pipeline, conduit, container, etc. from thermal expansion and contraction, or compensate the axial, lateral and angular displacement of pipeline, conduit, container, etc.. It can also be used for noise and vibration reduction.
(1) high elastic limit, tensile strength and fatigue strength, to ensure the normal work of the bellows.
(2) good plasticity, to facilitate the processing and forming of the bellows, and through the subsequent treatment process (cold hardening, heat treatment, etc.) to obtain sufficient hardness and strength.
(3) good corrosion resistance, to meet the requirements of the bellows in different environments.
(4) good welding performance, to meet the requirements of the corrugated pipe welding process in the production process.
Therefore, the correct choice of corrugated compensator fabrication materials and structure, reasonable design of waveform parameters and fatigue life, to ensure the quality of installation and other measures, can greatly improve the safety and reliability of the corrugated compensator.
