Reasonable design is one of the main factors to ensure the quality of metal corrugated expansion joints. Only after the design institute determines the size, working pressure, medium, medium temperature, connection method, installation form, and compensation amount through calculation can the accuracy of later manufacturing be ensured.

Accurate selection of materials is one of the main factors ensuring the quality of metal corrugated expansion joints. Often, in order to reduce costs, buyers will replace the relevant technical parameters designed by the design institute, which will pose significant safety hazards to the pipeline and is not advisable.

Regular maintenance is one of the main factors ensuring the quality of metal bellows expansion joints. Although the service life of metal bellows expansion joints is 1500 fatigue cycles, inspection and maintenance should be carried out after the pipeline has been running for a period of time in order to improve the service life of metal bellows expansion joints.
