Document Type and Number:

WIPO Patent Application WO/2016/021610

Kind Code:

A1

Abstract:

　Provided is a resin-coated metal pipe in which excellent anti-corrosion performance and impact resistance are obtained, satisfactory adhesion between a plating layer and a resin coating layer is obtained without a primer layer, the number of manufacturing steps is reduced, and the environmental burden is reduced. A resin-coated metal pipe (10) having a metal pipe (12), a plating layer (14) formed by hot-dipping 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), the resin coating layer (16) comprising a resin material containing a melt-moldable fluororesin (A) having at least one reactive functional group selected from the group consisting of carbonyl-containing groups, hydroxy groups, epoxy groups, and isocyanate groups.
