To provide a fuel feeding pipe and a manufacturing method thereof that allow selection of a metallic raw material for making the fuel feeding pipe without being limited to stainless steel, and can prevent corrosion of a receiving seat for a sealing material arranged on the tip side of the fuel feeding pipe and corrosion of a trunk part of the fuel feeding pipe.SOLUTION: A fuel feeding pipe for an automobile comprises a trunk part having an opening on both ends and a receiving seat for a sealing material arranged on the tip side of the trunk part and making an inside of the feeding pipe airtight. The trunk part and the receiving seat are made of a steel material, and the trunk part is in a state in which a steel material forming the trunk part, a metal plating layer and anticorrosion coating film are laminated in described order, and the receiving seat is in a state in which the steel material forming the receiving seat, the metal plating layer and a protective synthetic resin layer are laminated in described order. A method for manufacturing the fuel feeding pipe is also provided.SELECTED DRAWING: Figure 3
【課題】燃料給油管を構成する金属素材をステンレス鋼に限定することなく選択することを可能にし、しかも燃料給油管の先端側に配されたシール材の受座の腐食と燃料給油管の胴部の腐食とを防止することが可能な燃料給油管、及びその製造方法を提供することを目的とする。【解決手段】自動車用の燃料給油管であって、燃料給油管は、両端に開口を備える胴部と、胴部の先端側に配され、給油管内を気密にするためのシール材の受座とを備えており、胴部及び受座は鋼材から構成されており、胴部は、胴部を構成する鋼材と、金属メッキ層と、防食塗膜とが記載された順に積層された状態であり、受座は、受座を構成する鋼材と、金属メッキ層と、保護用の合成樹脂層とが記載された順に積層された状態である燃料給油管及びその製造方法である。【選択図】図3
