WIPO Patent Application WO/2002/099154

Kind Code:

A1

Abstract:

A fuel tank or a fuel pipe exhibiting excellent corrosion resistance, especially exhibiting excellent corrosion resistance on the outer surface under salt damage environment, characterized in that a steel plate or a steel pipe containing 9.0−25.0 % by mass of Cr is formed as a material, a contact gap structural part for a welded part, a brazed part or a structural component is provided on the outer surface, and a metal, where the electrode potential in a 5 % NaCl aqueous solution at 30°C is not higher than −0.4V with reference to saturated calomel electrode, is disposed in contact at least partially with these outer surface parts while conducting electrically.
