PURPOSE: A synthetic resin pipe is manufactured using a refuse synthetic resin to recycle resources and have an excellent durability. CONSTITUTION: Refuse synthetic resins with different physical properties such as PVC(Polyvinyl Chloride), HI(Hi-Impact Polystyrene), ABS(Acrylonitrile Butadiene Styrene), PS(PolyStyrene), PE(PolyEthylene), PP(PolyPropylene) and polyamide are collected and finely crushed to be mixed and extruded with 0.5 weight % of APP(Atactic PolyPropylene). Continuously extruded synthetic resin(1, 1a) is turned spirally to form a pipe of an appropriate length and thickness. Separate melted fluid(2) made of the same materials covers over the periphery of the turned synthetic resin by enough thickness.
