The bellows is a sensitive component that can be joined along the direction of the fold. There are many types of bellows, including metal bellows, corrugated expansion joints, corrugated heat exchange tubes, diaphragm bellows, metal hoses and so on. The role of the bellows is very important. Its main functions include: compensating for thermal deformation of the pipeline, damping, and absorbing pipe settlement deformation. In addition, bellows are widely used, including petrochemical, instrumentation, power, cement, metallurgy and other fields. In this article, I will explain how to choose the material of the bellows.

The inner wall of the bellows is thin and highly sensitive, and its measurement ranges from tens of kPa to several hundred megapascals. Its open end is in a fixed state, the sealed end is in a free state, and an auxiliary coil spring or reed is used to increase the elasticity. The bellows is easy to expand and contract, and it can be changed according to different size requirements to meet its needs. Below, I will summarize for you how to choose the material of the bellows.

First, when the material is selected, the most important thing is the good plasticity, which greatly facilitates the processing and manufacturing of stainless steel. And, in the subsequent process steps, it can obtain sufficient hardness and strength.

Second, higher flexibility, tensile strength, and fatigue strength ensure the proper functioning of stainless steel.

Third, in addition to the two points mentioned above, good soldering performance can meet the process requirements during the manufacturing process.

Fourth, good corrosion resistance can meet the requirements of different working environments.
