The FIVC Flexible Hose is designed to be installed in pipelines as a safety component to eliminate the effects of thermal expansion, a movement induced by vibration. Its main task is to absorb sound and manage thermal energy and shock in the pipeline and thereby protecting the system from damage. The expansion joint is not only a solution for the internal movement and vibration in the system but is also a proper solution for managing the cyclic motion associated with temperature changes in the application system. The hose is to be connected between water supply networks and is frequently used in fan-coil units.
