The present invention relates to an oil feed pipe, which is advantageous from the viewpoint of the cost and has excellent salt damage/corrosion resistance, and a method for producing the oil feed pipe. The gist of the present invention is an oil feed pipe which is composed of: a steel pipe member (1) that is formed of a steel pipe of a ferritic stainless steel which contains, in mass%, 0.015% or less of C, 0.01-0.50% of Si, 0.01-0.50% of Mn, 0.050% or less of P, 0.010% or less of S, 0.015% of less of N, 0.010-0.100% of Al, 13.0-18.0% of Cr and additionally 0.03-0.30% of Ti and/or 0.03-0.30% of Nb, and if necessary 0.0002-0.0050% of B and/or 0.01-0.50% of Sn; and a binding component (2) that is attached to the steel pipe member (1). The surface between the binding component (2) and the steel pipe member (1), said surface being exposed to a salt damage environment, is provided with a gap structure (3), and a cationic electrodeposition coating film is formed all over the internal surface of the gap structure. Consequently, the oil feed pipe has excellent salt damage/corrosion resistance, while being advantageous from the viewpoint of the cost. |
