Title (EN) METHOD FOR MANUFACTURING STEEL FUEL-PRESSURE-FEEDING PIPE
(FR) PROCÉDÉ DE FABRICATION DE TUYAU D'ALIMENTATION EN PRESSION DE CARBURANT EN ACIER
(JA) スチール製燃料圧送配管の製造方法
Abstract:
(EN) Provided is a method for manufacturing a high-quality steel fuel-pressure-feeding pipe having high resistance to corrosive fuel. This method is characterized in that steel pipe material is sorted into pipe material in which initial flaws (tiny cracks, wrinkle flaws, weld defects, etc.) in the inner peripheral surface of the pipe material exceeds a preset threshold value and pipe material in which the threshold value is not exceeded, and after initial flaws in the inner peripheral surfaces of the pipe material not exceeding the threshold value are removed by mechanical cutting, a surface treatment of Ni plating or the like is performed on the inner peripheral surfaces of this pipe material.
(FR) La présente invention concerne un procédé de fabrication d'un tuyau d'alimentation en pression de carburant en acier de haute qualité ayant une résistance élevée à un carburant corrosif. Ce procédé est caractérisé en ce que le matériau de tuyau en acier est trié en un matériau de tuyau dans lequel des défauts initiaux (fissures minuscules, défauts de plis, défauts de soudure, etc.) dans la surface périphérique interne du matériau de tuyau dépassent une valeur de seuil prédéfinie et un matériau de tuyau dans lequel la valeur de seuil n'est pas dépassée, et après que des défauts initiaux dans les surfaces périphériques internes du matériau de tuyau ne dépassant pas la valeur de seuil sont éliminés par découpe mécanique, un traitement de surface de placage de Ni ou similaire est effectué sur les surfaces périphériques internes de ce matériau de tuyau.
(JA) 腐食性燃料に対する高い耐性を有する高品質のスチール製の燃料圧送配管の製造方法の提供。 スチール製の管材の管内周面の初期疵(微細クラックやしわ疵、溶接欠陥部等)が予め設定した閾値を超える管材と同閾値を超えない管材とに選別し、閾値を超えない管材の内周面の初期疵を機械的切削によって除去した後、当該管材の内周面にNiめっき等の表面処理を施すことを特徴とする。
