About corrugated compensator use requirements
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.
The reliability of corrugated compensator is composed of several aspects such as design, manufacture, installation and operation management. Reliability should also be considered from these aspects. Material selection of the corrugated pipe for the heating network selection of materials, in addition to the working medium, working temperature and external environment should be considered, should also consider the possibility of stress corrosion, water treatment agents and pipe cleaners on the impact of materials, etc., and on this basis combined with the corrugated pipe material welding, molding and material performance to price ratio, the preferred economic and practical bellows production materials in general, the corrugated compensator material Selection should meet the following conditions:
(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.
