Zusammenfassung:	The invention relates to a wear-resistant polyethylene gas pipe and a preparation method thereof, and belongs to the technical field of steel-plastic composite pipes. The pipe comprises a wear-resistant inner layer, an alloy seamless steel pipe and an outer anti-corrosion layer, and the wear-resistant inner layer is prepared from, by weight, 100 parts of high-density polyethylene, 14-18 parts of triallyl isocyanurate, 10-15 parts of maleic anhydride grafted polyethylene, 15-22 parts of wear-resistant and weather-resistant auxiliaries, 0.4-0.5 part of electricity increasing agent, 0.2-0.3 part of antioxidant and 1-1.3 parts of defoaming agent; the wear-resistant and weather-resistant auxiliary agent is a low-crosslinking substance and can form secondary crosslinking with the main material, silica fume is uniformly dispersed in the main material and is combined with the main material through covalent bond formation, a high-strength crosslinked polymer is formed after the coating is cured, meanwhile, a fluorine
