2.The advantage:
1.Metal expansion joints are used in wide variety of piping application to compensate for thermal expansion or constraction and to absorb equipment vibration or pipe motions.
2. The bellow is made of Stainless Steel, which have good performance for extreme pressure, temmperatureand corrosion conditions.
3. Optimized design for fatigue resistance and endurance.
4. Compensate axial movements.
5. Widely used to absorb thermal expansion in pipe systems carring water, steam, oil and gas.
6. We manufacture single, two-ply and multiply testable bellows in different sizes using precision forming technology.
7. Stainless steel bellow expansion joint or compensator are designed according to clients' specification and working conditions.
