Nickel-Plated Steel Sheet for Manufacturing Pipe Having Corrosion Resistance Against Fuel Vapors, Pipe Which Uses the Steel Sheet,and Fuel Supply Pipe Which Uses the Steel Sheet

Abstract

Provided is a nickel-plated steel sheet for manufacturing a pipe having corrosion resistance against fuel vapor of fuel such as gasoline, light oil, bioethanol or bio-diesel fuel, and a pipe and a fuel supply pipe. In the nickel-plated steel sheet for manufacturing a pipe, a nickel plating layer having a plating thickness of 0.5 to 10 μm is formed on a surface of a steel sheet thus having corrosion resistance against fuel vapor. In the pipe and the fuel supply pipe, a nickel plating layer having a plating thickness of 0.5 to 10 μm is formed on an inner surface of a pipe formed of a steel sheet thus having corrosion resistance against fuel vapor. In the fuel supply pipe 20 formed of a steel sheet for supplying fuel to a fuel tank 23, the fuel supply pipe includes: a large-diameter pipe portion 21 through which the fuel passes; and a small-diameter pipe portion 22 which makes an upper portion of the large-diameter pipe portion and a lower portion of the large-diameter pipe portion communicate with each other for ventilation, and a nickel plating layer having a plating thickness of 0.5 to 10 μm is formed on an inner surface of at least the small-diameter pipe portion.
