PIPE

WIPO Patent Application WO/2013/146691

A1

A pipe (1) is provided with a pipe body (2) that is formed from a fiber-reinforced plastic, and a connector (3) that is a substantially tubular member formed from a resin, that has the end section (21) of the pipe body (2) inserted therein, and that is fixed to said end section (21). The connector (3) has an annular cover section (32) that covers the end surface (211) of the pipe body (2), and a tapered male screw section (33) that is formed on the outer surface of said connector (3). When the pipe body (2) is connected with another pipe body, the tapered male screw section (33) is screwed together with the tapered female screw section (73) of a substantially tubular coupling (5). A tubular tip protrusion (11) is formed on the pipe (1) at a position that is farther forward than the tip-side end section (331) of the tapered male screw section (33), and the tip protrusion (11) includes a portion of the pipe body (2). The entire circumference of the portion of the pipe (1) that is in the vicinity of the tip-side end section (331) is reinforced by the tip protrusion (11) so that deformation and damage of the tip of the pipe (1) is minimized.
