黑夹克黄夹克直埋保温钢管
Black jacket yellow jacket directly buried insulation steel pipe
黑夹克直埋保温钢管规格：DN50mm-DN2000mm
Specification of Black Jacket Directly Buried Insulating Steel Pipe: DN50mm-DN2000mm
黑夹克直埋保温钢管材质：Q235B、Q345B、10#钢、20#钢、X42-X80级
Black jacket directly buried insulation steel pipe material: Q235B, Q345B, 10 # steel, 20 # steel, X42-X80 grade
黑夹克直埋保温钢管规范：CJ/114-2000
Specification for Black Jacket Directly Buried Insulating Steel Pipe: CJ/114-2000
外层爲黑色聚乙烯资料的叫做黑夹克保温管。
The outer layer of black polyethylene material is called black jacket insulation pipe.
用高压发泡机在钢管与外护层之间构成的空腔中一次性注入硬质聚氨酯泡沫塑料原液而成，再用聚乙烯停止钢管外表的处置，构成外层的维护层。
A high-pressure foaming machine is used to inject rigid polyurethane foam plastics into the cavity formed between the steel pipe and the outer cover at one time, and then polyethylene is used to stop the disposal of the outer surface of the steel pipe to form the outermost maintenance layer.
聚乙烯外壳直埋保温管高密度聚乙烯保温管直埋式预制保温管由保送介质的钢管、聚氨酯硬质泡沫保温层和高密度聚已烯外套管严密结合而成。
The polyethylene shell is directly buried in the insulation pipe, and the high density polyethylene insulation pipe directly buried prefabricated heat preservation pipe is tightly combined with the steel pipe, polyurethane rigid foam insulation layer and high density polyethylenes coat pipe.
直埋保温管次要用于城镇集中供热管网，石油保送管线，高寒地域输水管线及产区工业管道工程。由于聚氨酯硬质泡沫保温层严密地粘结在钢管外皮，隔绝了空气和水的渗入，能起到良好的防腐作用。同时它的发泡孔都是闭合的，吸水性很小。高密度聚乙烯外壳、玻璃钢外壳均具有良好的防腐、绝缘和机械功能。
Directly buried heat preservation pipes are mainly used in urban central heating network, petroleum storage pipeline, water transmission pipeline in alpine region and industrial pipeline engineering in production area. Because the polyurethane rigid foam insulation layer is tightly bonded to the outer skin of the steel pipe, the infiltration of air and water can be isolated, and good anticorrosion effect can be achieved. At the same time, its foaming holes are closed and its water absorption is very small. High density polyethylene shell and FRP shell have good anti-corrosion, insulation and mechanical functions.
