Bellows Design Bellow Compensator Flexible Expansion Joint For Industrial Pipeline
This bellows-designed compensator is a flexible expansion joint engineered to absorb axial, lateral, and angular movements in industrial pipeline systems. Its precision-formed stainless steel bellows provide excellent flexibility, vibration reduction, and thermal expansion compensation, ensuring stable operation and preventing pipeline deformation or leakage. With durable construction and reliable sealing performance, it is widely used in water treatment, chemical plants, power generation, HVAC, and various industrial applications requiring efficient and long-lasting pipeline protection.
Performance of Bellows Design
The main elastic element of flexible expansion joint is stainless steel bellows. Through the expansion and bending of bellows, the flexible expansion joint compensates the pipeline in axial, transverse and angular directions. Flexible expansion joint can play the following roles:
1. Bellows Design absorbs the axial, transverse and angular thermal deformation of the pipeline.
2. Bellows Design can absorb equipment vibration and reduce the influence of equipment vibration on pipeline.
3. Bellows Design can absorb the pipeline deformation caused by earthquake and land subsidence.
