Braided Flexible Metal Hose Union Type Flexible Pipe Connectors
Union Type Flexible Pipe Connectors Stainless Steel are flexible piping connectors consisting of a stainless steel corrugated metal hose reinforced with an external stainless steel braid and fitted with union-type end connections. They are designed to accommodate vibration, thermal expansion, and slight misalignment in piping systems, while providing high pressure capability, corrosion resistance, and secure, leak-tight connections for industrial fluid and gas applications.
Performance Characteristics
The main elastic element of flexible expansion joint is stainless steel bellows. Through the expansion and bending of bellows, the flexible expansion joint accommodates pipeline movement in axial, transverse and angular directions.
- Absorbs axial, transverse and angular thermal deformation of pipelines
- Reduces equipment vibration impact on pipeline systems
- Compensates for pipeline deformation caused by seismic activity and ground settlement
