Polyurethane insulation pipe buried by the transmission medium steel, polyurethane rigid foam insulation and high-density Polyethylene jacket pipe close combination of yellow jacket pipe manufacturer, buried pipe insulation is mainly used for urban central heating pipe network, oil pipelines black jacket insulation shell, cold areas and areas of industrial piping water pipeline project. Buried pipe insulation with high efficiency insulation, waterproof anti-corrosion construction is simple, not afraid plant thorn advantages and construction without laying waste can in the 0.6-1.2 m permafrost buried, heat loss can be reduced by 40 compared to the traditional process %, life buried pipe insulation corrosion than other insulation materials increased by 3-5 times, life can reach 30-50 years of pipe insulation \ prefabricated buried pipe insulation structural features (3) temperature adaptability: Operating temperature range : greater than -70 degrees Celsius less than 250 degrees Celsius, freezing medium pipe does not crack. (4) fluid resistance: pipe wall is smooth, roughness coefficient 0.0084 jacket pipe, at the same flow rate, the diameter can be reduced. (5) light weight, long life: light weight, convenient transportation, construction costs low black jacket pipe insulation, no maintenance, long service life of more than 50 years. (6) maintain water quality: non-toxic, drinking water delivery, water quality can be maintained long-term health.
