Flange connected metal expansion joint
Corrugated compensator, also known as expansion joint, or expansion joint. It is composed of bellows (an elastic element) constituting its working body and accessories such as end pipe, support, flange and conduit. It is mainly used in various pipelines. It can compensate the thermal displacement, mechanical deformation and absorb various mechanical vibration of the pipeline, reduce the deformation stress of the pipeline and improve the service life of the pipeline.
Performance of metal expansion joint
1. Good compensation effect
2. High temperature resistance
3. Metal dust boot can reduce leakage
4. Vibration resistance and high-speed performance
5. The specific pressure of the spring can be reduced
6. Possible torque transmission
7. Through certain structural design, the sealing failure caused by scaling can be reduced

Production process of metal expansion joint
Do you know how is a high quality metal expansion joint made?Let's see with JINGNING.
Metal expansion joint application
Because of compensator's flexibility, metal compensator can compensate the temperature difference deformation or other deformation between equipment and pipeline, prevent vibration, reduce the thrust of pipeline on equipment, and adapt to the uneven settlement of oil tank foundation. The metal compensator can be widely used in chemical industry, oil refining, electric power, light industry, atomic energy, metallurgy, machinery, instrument, ship, aerospace and other departments. With the wide application of power pipeline and heat pipeline in industry and civil field, the requirement of metal compensator is higher and higher.
