Metal Hose Protects Cable Wire, Gas, Liquid Transport

Metal hose with screw thread to make it install easily

Metal hose also named flexible metal conduit is a high quality flexible pipe in modern industrial pipeline and it is more strong than flexible corrugated nylon conduits. It consists of corrugated hose, nets and connector. The inner corrugated hose made of stainless steel has helical and annular shapes. The nets are made of steel wire braided. It plays the reinforcement function. The connectors consist of screw thread, flange and quick coupling. All the connectors make it install easily and connected strongly. It is used as the compensation components, sealing elements, connecting elements and damping elements for gas, liquid transportation system and high temperature system.
