Corrosion and high temperature resistant bellows compensator

Corrosion and high temperature resistant bellows compensator
Bellows compensator has the advantages of durability, high temperature resistance, high pressure resistance, etc. General corrugated compensator solves the problem of unhygienic, easy aging, unstable pressure resistance, easy delamination and tearing, easy to burst and other unfavorable factors, solving the problem of pump room. General corrugated compensator as a good deformation compensation element, has been widely used in chemical, petroleum, electric power, metallurgy, shipbuilding, nuclear energy, aerospace and other industries. With the development of science and technology, large size, high parameters, thick-walled general corrugated compensator is used more and more in engineering. Therefore, the diameter of general-purpose corrugated compensator is large, thick-walled, and difficult to form as a whole.
Therefore, the current domestic compensator manufacturers use a single wave split valve forming welding manufacturing process, the compensator is not only a vertical weld, but also a ring weld, the more the number of waves, the more ring weld, the pressure vessel wave compensator standards and use requirements. In the design of the double-wave hydraulic integral forming compensator, it is very important to determine the corrugation parameters and material thickness of the general bellows compensator. The compensator is an elastic pressure element that requires sufficient strength and some elasticity to absorb equipment displacement to protect the equipment itself and its ancillary facilities. The overall type of double wave compensator is super plastic deformation with high forming pressure and high compressor thrust required for forming. It needs not only the large thrust of the compressor, the stroke of the cylinder and the size between the two columns of the compressor, but also needs to meet the large outer diameter requirements of the product mold.
