PURPOSE:To produce a synthetic resin lining pipe excellent in durable adhesive property of a metallic pipe and a synthetic resin pipe. CONSTITUTION:The external circumferential surface of a synthetic resin pipe is coated with an adhesive to form an adhesive layer. The synthetic resin pipe is introduced into a metallic pipe and thereafter a lining is performed on the metallic pipe. As the adhesive layer, a first adhesive layer and a second adhesive layer are formed as follows. The first adhesive layer contains the block copolymer elastomer of hydrogenated butadiene-styrene containing carboxyl group or acid anhydride group in a molecule as a main component. The second adhesive layer is constituted by coating the first adhesive layer with an epoxy resin- based adhesive. Thereby a synthetic resin lining pipe is produced. |
