STEEL SHEET USED TO MANUFACTURE PIPE AND HAVING CORROSION-RESISTANT PROPERTIES AGAINST FUEL VAPORS, AND PIPE AND FUEL SUPPLY PIPE THAT USE SAME |
摘要 |
<p>Provided are: a steel sheet used to manufacture a pipe; a pipe; and a fuel supply pipe. The 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 steel sheet used to manufacture a pipe, the steel sheet being provided on the surface thereof with an Fe-Ni diffusion layer and also with a softened Ni layer provided on the Fe-Ni diffusion layer, the Ni layer having a Ni coating thickness in the range of 0.9 - 8.1 µm, the steel sheet having corrosion-resistant properties against fuel vapors. A pipe and a fuel supply pipe, the pipes being constructed from a steel sheet and provided on the inner surfaces thereof with an Fe-Ni diffusion layer and also with a softened Ni layer provided on the Fe-Ni diffusion layer, the Ni layer having a Ni coating thickness in the range of 0.9 - 8.1 µm. A fuel supply pipe (20) for supplying 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 an Fe-Ni diffusion layer and also with a softened Ni layer provided on the Fe-Ni diffusion layer, and the Ni coating thickness of the Ni layer is in the range of 0.9 - 8.1 µm.</p> |
