<p>Disclosed is an oil feed pipe which is inexpensive and has excellent resistance to corrosion by salt. The oil feed pipe is characterized by comprising a steel pipe member and a fitting part, the steel pipe member being constituted of a ferritic stainless steel which contains, in terms of mass%, up to 0.015% C, 0.01-0.50% Si, 0.01-0.50% Mn, up to 0.050% P, up to 0.010% S, up to 0.015% N, 0.010-0.100% Al, and 13.0-18.0% Cr and further contains 0.03-0.30% Ti and/or 0.03-0.30% Nb. The oil feed pipe is further characterized by having a gap structure part in the surface which is located between the fitting part and the steel pipe member and is exposed to a salt damage environment, the gap structure part having a gap with a spacing of 0.2 mm or more, the inner surfaces of the gap having been coated by electrodeposition coating.</p> |
