黑夾克保溫管的組成結(jié)構(gòu)是什么？

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

黑夾克保溫管管材包括螺旋鋼管，直縫鋼管和無縫鋼管。外層爲黑色聚乙烯資料的叫做黑夾克保溫管。用高壓發(fā)泡機在鋼管與外護層之間構(gòu)成的空腔中一次性注入硬質(zhì)聚氨酯泡沫塑料原液而成，再用聚乙烯停止鋼管外表的處置，構(gòu)成外層的維護層。

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.

聚乙烯外殼直埋保溫管高密度聚乙烯保溫管直埋式預(yù)制保溫管由保送介質(zhì)的鋼管、聚氨酯硬質(zhì)泡沫保溫層和高密度聚已烯外套管嚴密結(jié)合而成，直埋保溫管次要用于城鎮(zhèn)集中供熱管網(wǎng)，石油保送管線，高寒地域輸水管線及產(chǎn)區(qū)工業(yè)管道工程。由于聚氨酯硬質(zhì)泡沫保溫層嚴密地粘結(jié)在鋼管外皮，隔絕了空氣和水的滲入，能起到良好的防腐作用。同時它的發(fā)泡孔都是閉合的，吸水性很小。高密度聚乙烯外殼、玻璃鋼外殼均具有良好的防腐、絕緣和機械功能。

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層，在保溫資料中發(fā)揚出了關(guān)重要的作用，真空層被運用到這種大型的保溫資料外面來，是一種全新的設(shè)計技術(shù)，具有十分優(yōu)異的運用效果。聚氨酯直埋管在運用的時分，真空層外面的合理化應(yīng)用將會被表現(xiàn)爲一種更好的運用性形式，外部真空層的處置就是讓溫度失掉隔絕，由于真空層是在聚氨酯里面的一層，可以從聚氨酯這樣資料外面透過溫度十分的困難。

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.
