Abstract
Official abstract text for this publication.
A steel pipe has a multi-layer coating including: a plating film formed on the surface of the steel pipe; a chemical conversion coating covering the plating film; a primer coating covering the chemical conversion coating and formed from a curable epoxy resin composition composed mainly of an epoxy compound and having an amide or imide bond introduced; and a polyamide resin coating covering the primer coating. The multi-layer coating can significantly enhance the adhesion force of the polyamide coating compared to the conventional pipe.
