Abstract
PURPOSE: A material foaming by heating is put into through holes on the wall of resin pipe that are arranged in parallel with the pipe axis and foamed by heating, thus clogging readily and surely the holes in the resin pipe.
CONSTITUTION: Outer wall 11, inner wall 12, and spacer 13 for binding both walls in the direction of the pipe axis are provided integrally, thus forming through holes 14 on the wall of resin pipe 1 in the direction of the pipe axis. Stick 2 of material foaming ny heating that comprises 100 parts by wt of a thermoplastic resin, 40W100 parts of a plasticizer, 0.5W5 parts of a foaming agent and 1W3 parts of foaming auxiliary agent is inserted into through holes 14 and foamed by heating, thereby clogging them.
