The failure of the corrugated compensator and the solution

The failure of the corrugated compensator and the solution
 
The use of corrugated compensator: this compensator is mainly produced for compensation of axial displacement, but also can compensate transverse displacement or axial and transverse synthetic displacement, with the ability to compensate angular displacement.
 
Corrugated compensator features and functions.
 
Corrugated compensator expansion and contraction, to facilitate the installation and removal of the valve pipeline.
 
Absorb the deformation of the pipeline by earthquake and ground subsidence.
 
Compensation to absorb pipeline axial, lateral and angular thermal deformation.
 
Axial internal pressure corrugated compensator is mainly used to compensate axial displacement, also can compensate transverse displacement or axial and transverse synthetic displacement, has the ability to compensate angular displacement, but it is generally not applied to compensate angular displacement.
 
The emergence of the corrugated compensator is undoubtedly a breakthrough of the thermal pipeline compensator products. It not only opens up a new field for the production of the compensator, but also solves the fatal weakness of the working medium thrust in the pipeline, and also solves the shortcomings of the bypass tube type no thrust compensator stress concentration and large medium resistance. Corrugated compensator in the pipeline test pressure and operation during the occasional failure of the phenomenon, the main reasons for the three aspects: improper temporary support of the pipeline system or fixed support pipeline system set improperly; pressure or displacement in the bellows is not enough; leakage and unstable corrosion, most of which are corrosion errors.
 
Corrugated compensator regular test, increase the use of maintenance. Corrosive media should be avoided as much as possible in use. It is worth mentioning that the compensator is more likely to corrode when it is shut down. The reason is that with the evaporation of water, the concentration of harmful media in the pipeline is getting higher and higher. Therefore, the liquid should be emptied as much as possible and cleaned if necessary. For the corrosive problem of corrugated compensator, we can solve the following two possibilities: choose two reasonable bellows material and structure design; strengthen the management of storage in the warehouse, in principle, to solve the corrosion problem.
