Abstract: PURPOSE: A butt-welding structure of a synthetic resin pipe by using a fusing ring is provided to prevent damage of the fusing ring by installing a heater separately from the ring and to improve pipe-laying and fusing-work efficiency of the synthetic resin pipe without cutting the broken fusing ring or the resin pipe attached with the ring. CONSTITUTION: In a butt-welding structure for welding a synthetic resin pipe attached with a fusing ring(20) to each other, the fusing ring has an inside melted to one synthetic resin pipe and a fusion surface(22) contacting to the fusing ring of the other synthetic resin pipe. A heater settling unit(23) contacted with a heater is disposed on the fusion surface. A combining projection(25) having a bolt hole(24) for joining physically the fusing rings confronting with each other by a bolt and a nut is formed at the outer periphery of the fusing ring.

Abstract: PURPOSE: A fusion jointing structure of synthetic resin pipes is provided to reduce manufacturing costs and improve airtightness by improving the structure of a sleeve. CONSTITUTION: In a fusion jointing structure of synthetic resin pipes, a heater(40) is fit into the outside of sockets(30), and is inserted into the inside of a sleeve(20). The synthetic resin pipes(P) are inserted into the sockets. The socket includes a small-diameter portion(32) into which the heater is fit, and a large-diameter portion(33) extended from the small-diameter portion. The sleeve includes a first insertion unit(21) into which the small-diameter portion is fit, and a second insertion unit(22) into which the large-diameter portion is fit.

Abstract: PURPOSE: A method for manufacturing connecting pipe for fusion jointing plastic pipe is provided to allow for a mass production in a low cost without using insert injection which is expensive and has low productivity. CONSTITUTION: The manufacturing method comprises the steps of extruding a pipe body having a dimension used as a connecting pipe(S10), cutting the extruded pipe body to be suitable for the length of the connecting pipe(S20), fitting a net-type heater into the both inner face of the cut connecting pipe(S30), pressing and squeezing the net-type heater against the inner face of the connecting pipe while rotating the connecting pipe in a state which the net-type heater is fitted into the connecting pipe(S40). The manufacturing method further comprises a step of embedding a lead wire into the net-type heater before fitting the heater into the connecting pipe.
