Corrugated compensators are also customarily called expansion joints or telescopic joints. It consists of bellows (a kind of elastic element) that constitutes its working body, and accessories such as end pipes, brackets, flanges, and ducts. Mainly used in various pipelines, it can compensate for the thermal displacement of the pipeline, mechanical deformation and absorb a variety of mechanical vibration, and play a role in reducing the deformation stress of the pipeline and improving the service life of the pipeline. Corrugated compensator connection is divided into two types: flange connection and welding. Directly buried pipe compensators are generally welded (except trench installation)

Corrugated compensator working principle

The corrugated compensator is a compensating device for absorbing the dimensional change caused by the thermal expansion and contraction of the pipeline, the conduit or the container by the effective expansion and contraction of the elastic element of the corrugated compensator, and belongs to a compensating element. Axial, transverse, and angular displacements can be absorbed.

Corrugated compensator detection

Because different types of corrugated compensators have different compensation forms, there are mainly axial, transverse, angular, and combined compensation methods. For a corrugated compensator with multiple displacements at the same time, it is necessary to synthesize the various displacements and obtain the total equivalent axial displacement. The detection is for the total equivalent axial displacement. In other words, the detection of the nominal displacement of the corrugated compensator is the detection of the total equivalent axial displacement.

Under normal circumstances, the material used for the bellows should meet the following conditions:

(1) High elastic limit, tensile strength and fatigue strength ensure the normal operation of the bellows.

(2) Good plasticity facilitates the forming of bellows, and can obtain sufficient hardness and strength through subsequent treatment processes (cold hardening, heat treatment, etc.).

(3) Good corrosion resistance, meeting the requirements of bellows in different environments.

(4) good welding performance, to meet the welding process requirements of the bellows in the production process.

For the heat pipe network laid by the trenches, when the pipeline where the compensator is located is low, rainwater or accidental sewage will soak the corrugated pipe. Consider using materials with stronger corrosion resistance, such as iron-nickel alloy and high-nickel alloy. Due to the high price of such materials, when manufacturing bellows, it may be considered to add a layer of corrosion resistant alloy only on the surface in contact with the corrosive medium. Fatigue life design can be seen from the failure type and cause analysis of the bellows compensator. The planar stability, circumferential stability, and corrosion resistance of the bellows are related to the displacement, that is, the fatigue life. Too low fatigue life will lead to a decrease in the stability and corrosion resistance of the metal bellows.
