Threaded Connection Rubber Expansion Joint
Description
Threaded connection flexible rubber expansion joint, also known as air condition flexible hose, it is a kind of flexible rubber joints, belongs to flexible connectors of metal pipelines. Threaded connection rubber expansion joint composed of inner rubber layer, chinlon tyre fabrics enhancement layer and outer rubber layer, then by molding vulcanization and combine with screw thread.
Threaded connection rubber expansion joints are used to absorb vibration and thermal movements in piping systems. They provide a flexible joint that helps reduce stress on connected equipment while also reducing noise and pressure loss. The rubber material allows them to accommodate misalignment, angular deflection, axial compression and extension, lateral offset and torsional movement.
