Stainless steel bellows principle of action

Bellows expansion joint is made of bellows directly connected with two flanges, is a new type of connecting pipe fittings. Corrugated pipe is a thin-walled pipe fitting with corrugated outer surface, generally made of stainless steel processing, with high axial elasticity. This product has the advantages of large displacement compensation, isolation vibration, high pressure-bearing capacity, small stiffness, long life, etc., and the structure type and compensation mode have great flexibility. In the application of bellows expansion joint can be regarded as an elastic element.
In the release of thermal stress of thermal expansion and contraction, in the equipment heat exchanger is generally called expansion joints, in the pipeline is also called bellows bellows expansion joints according to the form of displacement classification, can be basically divided into axial type, lateral type, angular type and pressure balance type bellows expansion joints, according to whether or not to absorb the pressure thrust generated by the medium pressure in the pipeline classification, can be divided into unrestrained bellows expansion joints and restrained bellows expansion joints. Stainless steel corrugated pipe as a flexible pressure-resistant pipe fittings installed in the liquid conveying system, to compensate for mutual displacement of pipelines or machines, equipment joints, absorb vibration energy, can play a role in vibration damping, muffling, etc., with good flexibility, light quality, corrosion resistance, fatigue resistance, high and low temperature resistance and many other characteristics.
 
As stainless steel bellows rely on compensation to absorb axial, lateral, angular thermal deformation work, can also absorb the impact of vibration on the pipeline. At the same time its occupies less space, not easy to leak safe and reliable and other comprehensive performance. The product structure is reasonable, the link, installation and guidance measures are correct, so it is widely used in petroleum, gas, chemical, machinery, and other industries. Because the stainless steel corrugated pipe is safe and reliable, but also environmental protection, corrosion resistance, long life and other comprehensive characteristics, is now widely used in home furnishing pipeline, hospitals and other new areas and has been approved for many times to promote the application. Stainless steel corrugated pipe is a multi-functional pipeline components, not only has the above-mentioned functions, but also can be used in different shapes for different environments, these are to be developed, research, I believe that in the near future can be widely used in our lives.
