Stainless Steel Wire Braided Flexible Metal Hose Union Type
Union Type Metal Braided Flex Hoses are flexible piping assemblies composed of a metal corrugated inner hose reinforced with an external braided layer and fitted with union-type end connections. They are designed to absorb vibration, accommodate thermal expansion, and compensate for minor misalignment in piping systems, while providing high pressure capability, mechanical strength, corrosion resistance, and reliable, leak-tight performance in industrial 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. Flexible expansion joint can perform the following functions:
- Absorbs axial, transverse and angular thermal deformation of the pipeline
- Reduces equipment vibration impact on pipeline systems
- Compensates for pipeline deformation caused by seismic activity and ground settlement

Applications
Due to their flexibility, pipe flex connectors can compensate for temperature differential deformation and other movements between equipment and pipelines, prevent vibration, reduce pipeline thrust on equipment, and accommodate uneven tank foundation settlement. Flexible expansion joints are widely used in chemical processing, oil refining, power generation, light industry, nuclear energy, metallurgy, machinery, instrumentation, marine, and aerospace applications. With increasing use of power and heat pipelines in industrial and civil sectors, the demand for pipe flex connectors continues to grow.
