A PVC pipe extrusion moulding process capable of effectively increasing impact strength is characterized in that: a formula of the PVC pipe includes a PVC resin/chloroprene rubber copolymer, an anti-impact modifier, a stabilizing agent, a processing modifier, filler, pigments, and an external lubricant. The extrusion moulding process includes the steps of: preparing and weighing the raw materials, kneading the raw materials, performing extrusion granulation, performing extrusion shaping, performing cooling shaping, cutting the product, inspecting the product and delivering a final product. A PVC pipe produced through the process is low in relative density which is 1/4-1/7 as that of metal, has excellent electric-insulation and chemical stability, is convenient to install and construct and easy to repair, and is low in unit energy consumption.
