Stainless Steel Wire Braided Flexible Metal Hose Union Type Gas Flexi Hose
A Union Type Gas Flexi Hose is a flexible gas connection hose equipped with union-type end fittings that allow easy installation and removal without rotating the hose. It is designed to safely convey gas while accommodating vibration, thermal expansion, and slight misalignment in gas piping systems, ensuring a secure, leak-tight, and durable connection for residential, commercial, or industrial gas applications.
Performance of Union Type Gas Flexi Hose
The main elastic element of flexible expansion joint is stainless steel bellows. Through the expansion and bending of bellows, the flexible expansion joint the pipeline in axial, transverse and angular directions. Flexible expansion joint can play the following roles:
1. Union Type Gas Flexi Hose absorbs the axial, transverse and angular thermal deformation of the pipeline.
2. Union Type Gas Flexi Hose can absorb equipment vibration and reduce the influence of equipment vibration on pipeline.
3. Union Type Gas Flexi Hose can absorb the pipeline deformation caused by earthquake and land subsidence.
