Steel Bellows SS316 Metal Expansion Joint 6.0Mpa Flange Connected
Steel bellows is a high-performance component designed to withstand pressures up to 6.0 MPa while accommodating thermal expansion and mechanical movements in piping systems. Its robust flange-connected design ensures secure and leak-proof installation, making it ideal for demanding industrial applications such as chemical processing, power generation, and oil and gas sectors. The use of SS316 material guarantees exceptional corrosion resistance, enhancing the joint's durability and reliability in harsh environments.
Performance of Steel bellows
1. Good compensation effect
2. High temperature resistance
3. Metal dust boot can reduce leakage
4. Vibration resistance and high-speed performance
5. The specific pressure of the spring can be reduced
6. Possible torque transmission
7. Through certain structural design, the sealing failure caused by scaling can be reduced

Do you know how is a high quality Steel bellows made?Let's see with JINGNING.
Steel bellows application
Because of compensator's flexibility, steel bellows can compensate the temperature difference deformation or other deformation between equipment and pipeline, prevent vibration, reduce the thrust of pipeline on equipment, and adapt to the uneven settlement of oil tank foundation. Steel bellows can be widely used in chemical industry, oil refining, electric power, light industry, atomic energy, metallurgy, machinery, instrument, ship, aerospace and other departments. With the wide application of power pipeline and heat pipeline in industry and civil field, the requirement of metal compensator is higher and higher.
