The main advantage of stainless steel tetrafluoro bellows is durability, but there are still many illegal businesses using inferior raw materials to produce bellows, so it is crucial to know how to choose stainless steel bellows. So how to choose?

In addition to working medium, working temperature and external environment, the material selection of stainless steel bellows should also consider the possibility of stress corrosion, the influence of water treatment agent and pipeline cleaning agent on the material. On this basis, economic and practical stainless steel corrugated pipe material should be selected by combining the welding, forming of corrugated pipe material and the performance-price ratio of the material.

In general, good stainless steel bellows need to meet the following conditions:

1. Good plasticity is to facilitate the processing and forming of stainless steel bellows, and to obtain sufficient hardness and strength through subsequent processing (cold work hardening, heat treatment, etc.).

2. High elastic limit, tensile strength and fatigue strength to ensure the normal operation of stainless steel bellows.

3. Good welding performance to meet the welding process requirements of stainless steel bellows in the manufacturing process.

4. Better corrosion resistance to meet the working requirements of stainless steel bellows in different environments.
