PURPOSE:To obtain the titled resin pipe having a ring shaped node made of a thermoplastic resin integrally formed to the outer peripheral surface thereof, by guiding a thermoplastic resin pipe between node constituting material holders for holding half-ring shaped node constituting materials of a thermoplastic before closing said holders. CONSTITUTION:A thermoplastic resin is formed into a tubular shape by extrusion molding using a mold 1 and held by node constituting material holders 3, 3 in such a state that half-ring shaped node constituting materials 5, 5 are inserted in the half-ring shaped grooves 4, 4 of said holders 3, 3. When the holders 3, 3 are mated with each other, end parts thereof are respectively contacted to each other to form a ring shaped body having a diameter almost equal to that of the thermoplastic resin pipe 2 and a thermoplastic resin pipe with a node having a ring shaped node integrally fused thereto is obtained. |
