20130153077 | METAL PIPE FOR VEHICLE PIPING AND METHOD OF SURFACE-TREATING THE SAME - Disclosed is a metal pipe which is for vehicle piping and which exhibits high corrosion resistance without the corrosion resistance being strengthened by means of a coating or a resin coating-layer, due to a hot-dip plating coating-layer being formed by applying a hot-dip plating to the pipe. The disclosed metal pipe for vehicle piping has a plating coating-layer formed on the surface of a formed metal pipe, said plating coating-layer being formed by means of hot-dip plating on the surface of the metal pipe, and the plating coating-layer being formed from a hot-dip plating alloy comprising at least 3 weight % Al, 1-15 weight % Mg, and Zn and unavoidable impurities as the remainder. | 06-20-2013 |
20100247947 | STEEL PIPE FOR VEHlCLE PIPING - A steel pipe has a multi-layer coating including: a plating film formed on the surface of the steel pipe; a chemical conversion coating covering the plating film; a primer coating covering the chemical conversion coating and formed from a curable epoxy resin composition composed mainly of an epoxy compound and having an amide or imide bond introduced; and a polyamide resin coating covering the primer coating. The multi-layer coating can significantly enhance the adhesion force of the polyamide coating compared to the conventional pipe. | 09-30-2010 |
