Bellows compensator is a kind of flexible connecting pipe widely used in modern industrial pipeline. It is mainly composed of flexible body (bellows), various forms of joint. Its raw materials are provided in the form of joints for pipes or equipment of users such as stainless steel, SS304, SS316L, titanium alloy TA2, nickel alloy 625, dual-phase steel 2205, harrods and so on.
All bellows have good softness, fatigue resistance, high temperature resistance, corrosion resistance, internal high pressure, it has a higher service life than other types of raw materials. In the pipeline can be connected in any direction, to compensate for temperature and absorb vibration, reduce noise, change the direction of medium transport, eliminate the pipe or pipe and equipment between the mechanical displacement, etc., bellows for displacement, vibration of various pumps, valves and other flexible joints are particularly applicable. With the development of modern industry, high temperature resistance, high pressure resistance, corrosion resistance bellows will be more and more widely used in aerospace, petrochemical, mining electronics, environmental protection equipment, machinery shipbuilding, medical and health care, textile electronics, energy construction and other fields.
The bellows section is a thin walled seamless or longitudinally welded stainless steel thin walled tube formed by high-precision plastic shaping. The elastic characteristics of the bellows profile determine the softness and fatigue resistance of the corrugated, which is easy to absorb all kinds of motion deformation and cyclic load, and especially can satisfy the compensation of large displacement of the system. Shanghai guangqidong-zhong company in order to be able to better provide customers with good quality bellows. The diameter range of metal bellows manufactured by the new technology is dn50-dn8000mm, and the working pressure is pn0.6-3.2mpa (up to 42.0mpa). The product is in accordance with GB/ t12777-2019 standard. The materials used to make bellows are austenite rust free, hashish alloy, SS304, SS316L and TA2, etc., which ensure excellent temperature resistance and corrosion resistance of bellows.
