PURPOSE: Water supply and sewage pipes connected to each other using a flange and a stopper and a coupling method thereof are provided to stably connect the water and sewage pipes in a construction site by independently producing a flange, a stopper, and a packing. CONSTITUTION: Water supply and sewage pipes connected to each other using a flange and a stopper comprise flanges(20,30), stoppers(40,50), a press ring, and a packing(60). The flanges have hanging grooves(25,35) and packing coupling grooves(26,36). The packing is coupled to the packing coupling grooves. The stoppers have coupling planes(41,51) and saw teeth(44,54). The press ring is installed between the stoppers and presses the packing. The packing has a watertight groove(64) and a fixing protrusion(61). Water supply and drainage pipes(10,11) are located at the watertight groove. |
