Metal bellows flange 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 bellows flange

1. Compensating thermal expansion: it can compensate multiple directions, which is much better than the metal compensator that can only be compensated in a single way.

2. Compensation for installation error: due to the inevitable systematic error in the process of pipeline connection, the fiber compensator can better compensate the installation error.

3. Silencing and vibration reduction: fiber fabric and thermal insulation cotton have the functions of sound absorption and vibration isolation, which can effectively reduce the noise and vibration of boiler, fan and other systems.

4. No reverse thrust: because the main material is fiber fabric, it is unable to transmit. The use of fiber compensator can simplify the design, avoid the use of large support, and save a lot of materials and labor.

5. Good high temperature resistance and corrosion resistance: the selected fluoroplastics and silicone materials have good high temperature resistance and corrosion resistance.

6. Good sealing performance: there is a relatively perfect production and assembly system, and the fiber compensator can ensure no leakage.

7. Light weight, simple structure and convenient installation and maintenance.

Bellows flange 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.
