The biggest advantage of stainless steel bellows is their durability, but there are still many unscrupulous businesses that use low-quality raw materials to produce bellows. Therefore, knowing the method of purchasing stainless steel bellows is very important. So how should I choose? Let the editor come to introduce you.
For the selection of stainless steel bellows for the heating pipe network, in addition to the working medium, working temperature, and external environment, the possibility of stress corrosion, the influence of water treatment agents and pipe cleaners on the materials should also be considered, and here Based on the combination of the welding and forming of the corrugated pipe material and the performance-to-price ratio of the material, an economical and practical stainless steel corrugated pipe manufacturing material is selected.
In general, a good stainless steel hose needs to meet the following conditions:
1. Good plasticity is to facilitate the processing and forming of stainless steel hoses, and to obtain sufficient hardness and strength through subsequent treatment processes (cold work hardening, heat treatment, etc.).
2. High elastic limit, tensile strength and fatigue strength to ensure normal operation of stainless steel bellows.
3. Good welding performance, meeting the welding process requirements of stainless steel bellows in the manufacturing process.
4. Good corrosion resistance, meeting the working requirements of stainless steel bellows in different environments.
