<p>PURPOSE:To obtain a synthetic resin lining tube superior in durable adhesion between the synthetic resin tube and a metallic pipe and obtain a production method therefor. CONSTITUTION:An epoxy resin adhesive is applied to the outer peripheral surface of a synthetic resin tube to serve as a first adhesive layer. On the first adhesive layer, an adhesive mainly composed of a hydrogenated butadiene- styrene block copolymer elastomer containing carboxyl group or acid anhydride group in a molecule is applied to serve as a second adhesive layer. The synthetic resin tube coated with the first and second adhesive layers is inserted into a metallic pipe. A synthetic resin lining tube is produced by reducing the metallic pipe in diameter or expanding the synthetic resin tube in diameter.</p> |
