Title (EN) CHEMICAL CONVERSION-TREATED STEEL PIPE
(FR) TUBE D'ACIER TRAITÉ PAR CONVERSION CHIMIQUE
(JA) 化成処理鋼管
Abstract:
(EN) A chemical conversion-treated steel pipe has a chemical conversion treatment film on a plated layer on a steel sheet. The plated layer is configured from a zinc alloy comprising 0.05-60 mass% aluminum and 0.1-10.0 mass% magnesium. The chemical conversion treatment film contains a fluorine resin, a base resin, metal flakes and a chemical conversion treatment component. The base resin is one or more selected from a group consisting of polyurethane, polyester, acrylic resins, epoxy resins and polyolefin. The content of fluorine resin with respect to the total amount of fluorine resin and base resin is at least 3.0 mass% calculated as fluorine atoms. The content of the base resin with respect to 100 parts by mass of the fluorine resin is at least 10 parts by mass. The content of metal flakes in the chemical conversion treatment film is greater than 20 mass% up to and including 60 mass%.
(FR) Cette invention concerne un tube d'acier traité par conversion chimique, comprenant un film de traitement de conversion chimique film sur une couche plaquée sur une feuille d'acier. Ladite couche plaquée est formée à partir d'un alliage de zinc comprenant de 0,05 à 60 % en masse d'aluminium et de 0,1 à 10,0 % en masse de magnésium. Ledit film de traitement de conversion chimique contient une résine fluorée, une résine de base, des flocons métalliques et un composant de traitement de conversion chimique. Ladite résine de base est choisie dans un groupe constitué par les polyuréthanes, le polyesters, les résines acryliques, les résines époxydes et les polyoléfines. La teneur en résine fluorée par rapport à la quantité totale de résine fluorée et de résine de base est supérieure ou égale à 3,0 % en masse en termes d'atomes de fluor. La teneur en résine de base pour 100 parties en masse de la résine fluorée est supérieure ou égale à 10 parties en masse. La teneur en flocons métalliques dans le film de traitement de conversion chimique est supérieure à 20 % en masse et inférieure ou égale à 60 % en masse.
(JA)  化成処理鋼管は、鋼板上のめっき層上に化成処理皮膜を有する。めっき層は、0.05~60質量%のアルミニウムと0.1~10.0質量%のマグネシウムとを含む亜鉛合金で構成されている。化成処理皮膜は、フッ素樹脂、基材樹脂、金属フレークおよび化成処理成分を含有する。基材樹脂は、ポリウレタン、ポリエステル、アクリル樹脂、エポキシ樹脂およびポリオレフィンからなる群から選ばれる一以上である。フッ素樹脂および基材樹脂の総量に対するフッ素樹脂の含有量はフッ素原子換算で3.0質量%以上であり、フッ素樹脂100質量部に対する基材樹脂の含有量は10質量部以上である。化成処理皮膜における金属フレークの含有量は20質量%超60質量%以下である。
