Wire Braided Flexible Metal Hose Union Type Stainless Steel Flexible Hoses
Union Type Stainless Steel Flexible Hoses are engineered with a stainless steel corrugated inner hose and stainless steel braided reinforcement, featuring union-type end connections for straightforward installation and removal. These hoses are designed to absorb vibration, thermal expansion, and misalignment in piping systems while delivering exceptional pressure resistance, corrosion resistance, and reliable leak-tight performance across demanding industrial applications.
Performance Characteristics
The primary elastic component of our flexible expansion joints is the stainless steel bellows. Through expansion and bending capabilities, these joints accommodate pipeline movements in axial, transverse, and angular directions, providing:
- Absorption of axial, transverse, and angular thermal deformation in pipelines
- Vibration absorption from equipment, minimizing pipeline impact
- Compensation for pipeline deformation caused by seismic activity and ground settlement
