Description

Technical Field

[0002] Bellows compensator is a flexible, thin-walled, transversely corrugated device with expansion and contraction function. It is composed of metal bellows and components. The working principle of bellows compensator is mainly to utilize 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 has the functions of pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration reduction and noise reduction, which plays a role in reducing pipeline deformation and increasing pipeline service life.

[0003] The metal bellows of the existing pipeline expansion joints have no external protective measures during transportation. Since the wall thickness of the material used to make the metal bellows is very thin, it is easy to cause damage, deformation or even rupture of the metal bellows material under the action of external forces during lifting, transportation, unloading, etc., thereby affecting the normal use of the bellows.
