Abstract
A nickel-plated steel sheet for manufacturing a pipe having corrosion resistance against fuel vapor; and a pipe and a fuel supply pipe. In the pipe and 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 formed of a steel sheet for supplying fuel to a fuel tank, the fuel supply pipe includes: a large-diameter pipe portion through which the fuel passes; and a small-diameter pipe portion 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.
