HDPE Casing Pipes (Prefabricated Directly Buried Insulating)Production Line

HDPE thermal insulation pipe has excellent characteristics such as high-efficiency thermal insulation,waterproof, anti-corrosion, heat insulation, flame retardant, cold resistance, light weight, high strength, simple and fast construction, and is not afraid of plant root thorns. It is widely used in urban central heating, Warm room, cold storage, coal mine, oil pipeline port, chemical industry, natural gas pipeline, electric power direct burial, central air-conditioning pipeline thermal insulation, cable threading pipe, steam thermal insulation pipeline and other industries thermal insulation and cold insulation projects. The thermal insulation pipe has strong corrosion resistance, chemical inert material, excellent corrosion resistance, and can chÃose different çorrosion-resistant pipes according to the transmission medium; it has high mechanical strength, good water pressure resistance, external pressure resistance and impact resistance. Pipes and fittings can be designed and manufactured according to the required pressure.
