摘要：PURPOSE: A synthetic resin pipe having a hot-wire connection pipe is provided to easily connect the pipes by manufacturing the synthetic resin pipes joined to the hot-wire connection pipe in advance. CONSTITUTION: A hot-wire connection pipe(21) is fit into one end of a synthetic resin pipe(20). Pipe wall members(24) have hot-wires(23), and are wound around the inside of the connection pipe. The pipe wall members are integrally connected with each other by I-shaped joining members(25). Connection terminals(26) are connected to the hot-wires, respectively. A synthetic resin welding unit(22) is welded to the end of the connection pipe and the outer circumference of the synthetic resin pipe, and joins the connection pipe to the synthetic resin pipe integrally.
