Document Type and Number:
WIPO Patent Application WO/2011/033772
Kind Code:
A1
Abstract:
Provided are: a nickel-plated steel sheet used to manufacture a pipe; a pipe; and a fuel supply pipe. The nickel-plated steel sheet, the pipe, and the fuel supply pipe have corrosion-resistant properties against fuel vapors, such as those of gasoline, light oil, bioethanol, and biodiesel fuel. A nickel-plated steel sheet used to manufacture a pipe, the nickel-plated steel sheet being provided on the surface thereof with a nickel-plating layer which has a thickness in the range of 0.5 - 10 μm and having corrosion-resistant properties against fuel vapors. A pipe and a fuel supply pipe, the pipes being constructed from a steel sheet, being provided on the inner surfaces thereof with a nickel-plating layer which has a thickness in the range of 0.5 - 10 μm, and having corrosion-resistant properties against fuel vapors. A fuel supply pipe (20) constructed from a steel sheet and adapted to supply fuel to a fuel tank (23), the fuel supply pipe (20) being provided with a large-diameter pipe section (21) through which the fuel passes, and also with a small-diameter pipe section (22) which allows ventilation between the upper portion and the lower portion of the large-diameter pipe section. At least the inner surface of the small-diameter pipe section is provided with a nickel plating layer having a thickness in the range of 0.5 - 10 μm.
