黑夹克保温管的组成结构是什么？

What is the composition and structure of the black jacket insulation pipe?

黑夹克保温管管材包括螺旋钢管，直缝钢管和无缝钢管。外层爲黑色聚乙烯资料的叫做黑夹克保温管。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。

Black jacket insulation pipe includes spiral steel pipe, straight seam steel pipe and seamless steel pipe. The outer layer of black polyethylene material is called black jacket insulation pipe. 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，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。

Polyethylene shell, directly buried thermal insulation pipe, high density polyethylene insulation pipe, directly buried precast insulation pipe, is tightly combined with the steel pipe, polyurethane rigid foam insulation layer and high density polyethylenes coat pipe. The directly buried insulation pipe is mainly used for the urban central heating network, the oil delivery pipeline, the high cold area water delivery pipeline and the industrial pipeline project in the 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.

聚氨酯直埋管外部的真空层，在保温资料中发扬出了关重要的作用，真空层被运用到这种大型的保温资料外面来，是一种全新的设计技术，具有十分优异的运用效果。聚氨酯直埋管在运用的时分，真空层外面的合理化应用将会被表现爲一种更好的运用性形式，外部真空层的处置就是让温度失掉隔绝，由于真空层是在聚氨酯里面的一层，可以从聚氨酯这样资料外面透过温度十分的困难。

The vacuum layer outside the polyurethane direct buried pipe plays an important role in the thermal insulation data. The vacuum layer is applied to the large thermal insulation data. It is a new design technology with excellent application effect. When the polyurethane buried pipe is in use, the rational application outside the vacuum layer will be shown as a better application form. The disposal of the external vacuum layer is to make the temperature lose insulation. Because the vacuum layer is inside the polyurethane, it is very difficult to penetrate the temperature from the outside of the polyurethane data.
