Abstract

PURPOSE:To close readily and securely a through-hole in pipe walls, by enlarging or reducing diametrically the end of the resin pipe having the through- hole extending longitudinally through the pipe walls, and then moving a mold, which has been put on the outer circumference or inside or the pipe, along the axis of the pipe. CONSTITUTION:The end 21 of the resin pipe that has the inner and outer walls, joining walls extending longitudinally of the pipe and joining the inner and outer walls, and the longitudinally extending through-hole formed in the walls is preheated to be cured, and is fit onto a receptacle molding core mold 22 carrying a diameter enlarging mold ring 23 and a stopper flange 25 so that the end 21 slides on the ring 23 to cause the diameter to be enlarged. Then a press bonding annular outer mold 24 is moved in a direction shown at an arrow to cause the inner wall of the end 21 to be firmly bonded to the inner wall thereof so that a resin pipe receptacle whose through-hole is closed can be formed. Alternatively, the resin pipe end can be reduced diametrically, and the inner wall can be bonded to the outer wall by pressing, so that a resin pipe spigot part whose through-hole is closed can be formed.
