Chongqing compensator to compensate for additional stress due to temperature difference between the mechanical vibrations caused by a flexible structure provided on the container casing or pipe. Because of it as a kind of elastic compensation element can freely scalable, reliable, good performance, compact structure and so on. Customary compensation also called expansion joints, or bellows compensator is effective stretching deformation of the elastic element to use bellows compensator to absorb dimensional changes pipelines, conduits or containers produced by the expansion and contraction of other reasons kind of compensation system, is a form of compensation components. To the axial, lateral and angular displacement of the absorption of the displacement for the heating pipes, equipment and systems, mechanical displacement absorbing vibration and reduce noise. Expansion joints to compensate for the additional stress due to the temperature difference caused by mechanical vibrations, and set up a flexible structure on the container casing or pipe. Because of it as a kind of elastic compensation element can freely scalable, reliable, good performance, compact structure, etc., have been widely used in the chemical industry, metallurgy, nuclear energy and other sectors. On the container used in expansion joints, there are a variety of forms, the shape of the waves, the U-shaped expansion joints are used widely, then there are Ω-shaped and C-shaped and so on. In the pipeline expansion joints on the structure adopted in terms of compensation, there are universal type, pressure balanced, hinged and gimbal style and so on. Expansion joints with the overall molding process pressure vessels and heat exchangers used in multi-wave (with a single wave) thick metal bellows expansion joints, the selected material covering the black steel, austenitic stainless steel, duplex stainless steel, nickel-based alloy, Hastelloy alloy, high alloy steel and titanium, zirconium, hafnium and other non-ferrous materials. Nominal diameter up to 6 meters, wave number up to four waves, the largest steel wall thickness up to 70 mm, the pressure range from vacuum to 35 MPa, withstand temperature range -196 ° C to 1200 degrees Celsius.
