The working principle of the bellows expansion joint is mainly to use its own elastic deformation function to compensate the axial, angular, lateral and combined displacement of the pipeline due to thermal deformation, mechanical deformation and various mechanical vibrations.The bellow expansion joint has the functions of pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration and noise reduction, which can reduce the deformation of the pipeline and improve the service life of the pipeline.

304 material characteristics: It is a widely used steel with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. Good hot workability such as stamping and bending, no heat treatment hardening (no magnetic).

Indonesian customers install corrugated compensators near the oil pump in the oil pipeline to reduce pipeline vibration and noise and to avoid paralysis of the pipeline due to vibrations in the pumping area. To this end, we have designed a professional corrugated expansion joint for the user.

After the customer installs and uses, the noise and the vibration of the pipeline are well controlled during the oil transportation process, which avoids deformation and damage of the pipeline. And long life, reducing installation costs and labor costs.
