Description of product
Metal corrugated compensator is also named for the expansion joints, Bellow expansion joint, bellows compensator, is a kind of flexible, thin wall, a transverse corrugated device with telescopic functions, it is made up of metal corrugated pipe and components. Bellows compensator's working principle is mainly using their elastic scaling, to compensate the axial, angular, lateral and combined compensation due to pipes' thermal deformation, mechanical deformation and all kinds of mechanical vibration, the role of compensation has pressure, sealing, corrosion resistance, temperature resistance, impact resistance, anti-vibration noise reduction function, it could reduce the pipe deformation and prolong the service life of pipelines.

Features of flanged expansion joint
1. Reasonable structure, good elasticity, large range of compensation pipeline and little counterforce to the brackets of pipeline.
2. Shock absorption and noise decrease, heat and dust insulation, environmental protection and simple structure bracket.

3. The displacement can be deflected to prevent damagment caused by subsidence of connected brackets and equipment base. It can adapt itself to the centrifugal difference of pipeline installation to provide convenience to installation and maintenance.
4. Good resistance to milling, heat, aging and corrosiveness and long service life.
5. Little resistance and little weight. Each performance is better than the compensation device of other materials.
6. The temperature range of media is wide: -40300° C
