stainless steel bellows Compensator Just like the development of other industries, the development of technology is driven by market demand. Today, history has entered the 21st century, people in the environmental protection, electronics and other fields of high-tech development and the world's sustainable development of the great demand, including stainless steel Bellows compensator Many industries or fields, including the industry, have brought about the rapid change and development of technology. The selection of bellows is very important.
First of all, we all know that the stainless steel bellows compensator is a kind of compensator directly installed in any pipeline connecting non corrosive unidirectional or multi fluid, which is used for the axial rotation of the axial expansion machine of the stainless steel bellows compensator at any angle. Widely used in urban heating, metallurgy, mining, power generation, petrochemical, construction and other industries in the pipeline, compensator plays a vital role in the pipeline operation. Therefore, the reliability of stainless steel bellows compensator can not be ignored.
First of all, the selection of stainless steel bellows compensator material should not only consider the working medium, working temperature and external environment, but also consider the possibility of stress corrosion, the influence of water treatment agent and pipeline cleaning agent on the material. On this basis, combined with the welding, forming and material performance price ratio of the compensator pipe, the economical and practical material for the compensator is optimized
Secondly, due to various constraints, it is quite complicated. However, for any complex pipeline system, several fixed supports can be selected, and different settings can be selected at different parts, which can be divided into several relatively simple single pipe sections, "Z" type pipe section and "Π" type pipe section, and the deformation and compensation amount of each pipe section are determined respectively. There are many types of compensators, It is very important to select the type correctly. Therefore, in the overall design of the piping system, the design of the pipeline trend and support system (including fixed pipe support, guide sliding pipe support, etc.) should be fully considered, and the modeling and configuration of stainless steel bellows compensator should be comprehensively considered, so as to achieve a reliable, reasonable, applicable and economic combination.
Thirdly, the stainless steel bellows compensator is a flexible component with bellows as the core, which can make axial, transverse and angular compensation on the pipeline. In order to reduce the self excitation of the medium, the axial type stainless steel bellows compensator. There is no inner sleeve inside the product, which limits the radial compensation ability to a great extent. Therefore, it is generally only used to absorb or compensate the axial displacement of the pipeline (if a small amount of radial displacement is really needed in the piping system, the radial displacement can be specified when ordering): the lateral displacement compensator (large tie rod) mainly absorbs the transverse displacement perpendicular to the compensator axis, and the small pull rod is used for lateral displacement compensation The device is suitable for absorbing lateral displacement, and can also absorb the combination of axial displacement, angular displacement and any three directions displacement: hinge compensator (also known as angular compensator). It is used with two or three compensators (a single hinge compensator has no compensation ability) to absorb the lateral deformation in the unidirectional plane. The universal hinge (angular) compensator, which is used with two or three compensators, can absorb the three-dimensional deformation.
