Metal-composite hose and a process for manufacturing the same
A metal-composite hose having a wall including an innermost metal layer and a resin layer surrounding it, in which the metal layer has at each end portion of the hose an inner surface covered with a resin layer, an elastic rubber layer, or both. A process for manufacturing a metal-composite hose includes: forming a metal layer; covering the metal layer with an elastic rubber layer, if required; and after masking a specific portion of the metal layer, forming a thermoplastic resin layer thereon by powder or spray coating. The hose is preferably a corrugated one. It has high fluid impermeability, flexibility and strength, as well as high metal-rust resistance and sealing property at both ends.
