Axial bellows expansion joints

Bellows expansion joints for cryogenics. In cryogenics bellows expansion joints used in pipelines for transporting liquefied gases with temperatures up to -236 °C. the diameters of the pipes from 100 to 700 mm and working pressure up to 63 kgf/cm2. The main purpose of bellows expansion joints is to compensate temperature deformations of pipelines. At low temperatures of the working medium in the pipeline is possible to use only U-shaped and bellows expansion joints. The advantage of bellows expansion joints is the compact design, low material consumption and low rigidity, which allows to reduce the VAT rate of the pipeline and increases the reliability.
