Abstract
A pipe with a pipe main body made from fiber reinforced plastic and a connection portion made from resin and having substantially tubular shape, into which an end portion of the pipe main body is inserted, thereby being fixed to the end portion. The connection portion includes an annular cover portion that covers an end face of the pipe main body, and an external tapered male screw portion. When the pipe main body is connected to another pipe main body, the male screw portion is screwed with a substantially tubular tapered female screw portion of a coupling. The pipe has a tubular-shaped front-end protrusion located beyond a front-end portion of the male screw portion. The front-end protrusion includes a region of the pipe main body. The entire circumferential region of the pipe in the vicinity of the front-end portion is reinforced by the front-end protrusion.
