Title:
PLATED STEEL SHEET FOR PRODUCING PIPE HAVING CORROSION RESISTANCE AGAINST FUEL VAPOR, AND PIPE AND OIL SUPPLY PIPE USING THE PLATED STEEL SHEET
Document Type and Number:
WIPO Patent Application WO/2011/135787
Kind Code:
A1
Abstract:
Provided are: a plated steel sheet for producing a pipe which has corrosion resistance against a fuel vapor such as vapor of gasoline, light oil, bioethanol, biodiesel fuel or the like; a pipe; and an oil supply pipe.
The plated steel sheet for producing a pipe, said pipe having corrosion resistance against a fuel vapor, is characterized by being provided with a plating layer containing Zn, Co and Mo on the surface of a steel sheet, wherein the composition ratio of Co, relative to Zn, in said plating layer is 0.2-4.0 at% (atomic percentage).
The pipe, which has corrosion resistance against a fuel vapor, is characterized by being provided with a plating layer, which contains Zn, Co and Mo, on the inner face of a pipe formed of a steel sheet.
The oil supply pipe (20), which is to be used for supplying a fuel oil to a fuel tank (23), comprises a large-diameter pipe section (21), through which the fuel passes, and a small-diameter pipe section (22) for aerating the upper part and lower part of the large-diameter pipe section, wherein a plating layer containing Zn, Co and Mo and having a composition ratio of Co, relative to Zn, of 0.2-4.0 at% is provided at least on the inner face of the large-diameter pipe section.
