MANUFACTURING METHOD OF RAISES STRENGTH AND CORROSION RESISTANCE SYNTHETIC RESIN PIPE

摘要

A method for manufacturing a synthetic resin pipe with improved strength and corrosion resistance is provided to reduce generation of foam and improve tensile strength of a PVC(PolyVinyl Chloride) pipe, by increasing contact force between glass fiber and the PVC pipe. A method for manufacturing a synthetic resin pipe with improved strength and corrosion resistance, comprises a first step(S10) of applying a liquid resin to an outer surface of a PVC pipe; a second step(S20) of winding glass fiber onto the outer surface of the PVC pipe; and a third step(S20) of winding a polyester veil onto the outer surface of the pipe. In the second step, the liquid resin and the glass fiber have weight ratio of 7:3.
