Direct buried insulation pipeline with high efficiency insulation, waterproof, anti-corrosion, insulation, sound insulation, flame retardant, cold resistance, corrosion resistance, light capacity, high strength, simple and fast construction, not afraid of plant roots and other excellent characteristics, has become the construction, transportation, petroleum, chemical, electric power, refrigeration and other industrial sectors of insulation and insulation, waterproof plugging, sealing and other indispensable materials. Compared with the ordinary pipeline, the direct buried thermal insulation pipeline can reduce the direct buried heat loss in 0.6-1.2 meters of frozen soil layer by more than 40%, and the working life is more than 3-5 times higher than that of other thermal insulation anticorrosive materials, and the life can reach 30-50 years.
