摘要: To provide a resin-coated metal pipe which is excellent in corrosion resistance and impact resistance, wherein adhesion between a plating layer and a resin coating layer is good even without a primer layer, and whereby the number of steps at the time of production is small, and the environmental burden is low. A resin-coated metal pipe (10) comprises a metal pipe (12), a plating layer (14) formed by hot dipping plating on the outer peripheral surface of the metal pipe (12), and a resin coating layer (16) formed by melt molding on the surface of the plating layer (14), wherein the resin coating layer (16) is made of a resin material comprising a melt-moldable fluororesin (A) having at least one type of reactive functional group selected from the group consisting of a carbonyl group-containing group, a hydroxy group, an epoxy group and an isocyanate group.

摘要: Disclosed is a coated metal pipe including a metal pipe and a multi-layered coating film that covers an outer circumferential surface of the metal pipe. The multi-layered coating film includes a chemical conversion layer and a primer layer, and these layers are provided in this order from the inside. The chemical conversion layer contains a zirconium oxide and/or a zirconium hydroxide. The primer layer contains a polyamide imide and/or an epoxy resin.
