High temperature prefabricated buried pipe insulation, floor heating heating pipe insulation, pipe insulation monolithic black jacket pipe insulation: steel, insulation materials, protective shell of three parts firmly bonded together to form a unitary structure. When the pipe due to the transmission medium and the temperature of thermal expansion occurs when urban heating polyurethane buried pipe insulation, insulation expansion move along together. Integral pipe insulation is mainly used for heating medium temperature below 150 ℃ occasions. Polyurethane insulation thermal conductivity coefficient: λ = 0.013-0.03kcal / m h oC, much lower heat buried pipe insulation, thermal insulation effect than other pipe insulation material used in the past to improve 4-9 times??. Further water absorption is very low, about 0.2kg / m2. The reason is due to the low water absorption of the polyurethane foam closed cell ratio as high as 92%. Low thermal conductivity and low water absorption, plus insulation and outer waterproof good high density polyethylene or fiberglass protective shell, has changed the traditional trench laying pipe heating condition "wearing wet jacket", greatly reducing the heating pipes overall heat loss, heat 2% net heat loss, less than 10% of international standards. Steam pipe insulation steel pipe steel sleeve | Kodak buried steam pipe insulation (certified) | pipe insulation provided by the Building Materials Co., Ltd. Weifang Kodak.
