The invention relates to an HDPE double-wall corrugated pipe and a production process thereof. The double-wall corrugated pipe is prepared from the following components in parts by weight: HDPE, polypropylene, talcum powder, antistatic masterbatch, anti-impact modified masterbatch, coupling agents, ethylene-propylene-diene monomers, carbon nanotubes and color masterbatch. The production process comprises the following steps: step 1, weighing the raw materials according to parts by weight, then stirring and mixing uniformly to obtain a raw material mixture; step 2, melting the raw material mixture, then extruding through a twin-screw extruder, and then forming through a die to obtain a primary product; step 3, drawing the primary product, and then cutting the primary product according to aspecification to obtain an intermediate product; and step 4, flaring the intermediate product to obtain the double-wall corrugated pipe. According to the HDPE double-wall corrugated pipe and the production process thereof, polypropylene, the anti-impact modified masterbatch, ethylene-propylene-diene monomers and the carbon nanotubes are added into the HDPE double-wall corrugated pipe, so that thedefects of the HDPE double-wall corrugated pipe are overcome, and the ring stiffness and the creep resistance of the corrugated pipe are improved.
