WIPO Patent Application WO/2013/146693

A1

A pipe (1) is provided with: a tube-shaped pipe body (2) which consists of fiber-reinforced plastic; and a connection section which is a substantially tube-shaped member centered on the center axis of the pipe body (2), has an end of the pipe body (2) inserted therein, and is affixed to the end. The connection section has a tapered male thread section (33) on the outer surface thereof. When connecting the pipe body (2) to another pipe body, the tapered male thread section (33) is engaged through threads with a tapered female thread section (73) provided on the inner surface of a substantially tube-shaped coupling (5). The tapered male thread section (33) has, in the vicinity of the surface of the thread thereof, a metallic mesh layer as a reinforcement layer (331), and the metallic mesh layer follows the shape of the surface of the thread. The portion of the tapered male thread section (33) which excludes the reinforcement layer (331) consists of a resin. In the pipe (1), the reinforcement layer (331) can prevent the tapered male thread section (33) from being damaged.
