管道直埋敷設技術在國內(nèi)的開展曾經(jīng)有幾十年，聚氨酯直埋保溫管的目的概括性的解釋有兩個:一是：保證管道能在公開長期穩(wěn)定運轉;二是：保證保溫管能起到良好的保溫效果，不糜費能源，不毀壞園林綠化。
Pipeline directly buried laying technology has been developed in China for several decades. There are two general explanations for the purpose of polyurethane directly buried insulation pipe: one is to ensure that the pipeline can operate steadily in the open long term; the other is to ensure that the insulation pipe can play a good thermal insulation effect without wasting energy and destroying Garden greening.
聚氨酯直埋保溫管的應用越來越普遍，隨著社會的進步和科技的開展，形形色色的夾克保溫管直接而出，進而產(chǎn)品的品種也就越來越什么樣的都有了。地埋聚氨酯直埋保溫管保溫性能好，熱損失僅為傳統(tǒng)管材的25%，長期運轉可節(jié)約大量能源，顯著降低能源本錢。其施工煩瑣，防腐效果顯著而被大量地用于各種供熱，制冷，輸油，化工等工業(yè)管道的保溫。
With the progress of society and the development of science and technology, various kinds of jacket insulating pipes come out directly, and the varieties of products become more and more different. Buried polyurethane direct-buried insulation pipe has good thermal insulation performance, and its heat loss is only 25% of the traditional pipe. Long-term operation can save a lot of energy and significantly reduce energy costs. Its construction is cumbersome, energy-saving and anticorrosive effect is remarkable, and it is widely used in various heating, refrigeration, oil transportation, chemical and other industrial pipelines for heat preservation.
個方面是在保溫管的構造和性能。聚氨酯預制保溫管的構造采用由里到外依次有內(nèi)維護層、保溫層、外維護層。內(nèi)維護層是保送介質的鋼管，具有耐腐蝕性和防水性能好等特性。鋼管和外維護層之間的硬質聚氨酯泡沫保溫層采用管中管發(fā)泡技術使三者嚴密分離而成。外維護層是高密度聚乙烯外套管。總的說來，聚氨酯預制保溫管的保溫隔熱性能比傳統(tǒng)保溫管愈加優(yōu)良，保溫保冷的效果更好。
One aspect is the structure and performance of insulation pipe. The polyurethane prefabricated insulation pipe is constructed with internal maintenance layer, thermal insulation layer and external maintenance layer from inside to outside. The inner maintenance layer is a steel pipe with delivery medium, which has good corrosion resistance and waterproof performance. The rigid polyurethane foam insulation layer between the steel tube and the outer maintenance layer is made by the tube tube foaming technology, which makes the three parts closely separated. The outer maintenance layer is the high density polyethylene outer casing. Generally speaking, the thermal insulation performance of polyurethane prefabricated insulating pipes is better than that of traditional insulating pipes, and the effect of thermal insulation and cooling is better.
第二個方面是工業(yè)消費方面。聚氨酯預制保溫管采用的預先訂制，它愈加有利于保溫管應用的實踐消費生活中，具有很大的靈敏性和順應性，能夠依據(jù)不同需求，設計不同參數(shù)的直埋保溫管。
The second aspect is industrial consumption. Pre-customized polyurethane prefabricated insulating pipes are more conducive to the practical consumption of insulating pipes. They have great sensitivity and compliance. They can design directly buried insulating pipes with different parameters according to different needs.
第三個方面從敷設方式來看。傳統(tǒng)保溫管采用的是地溝及架空的敷設方式，工程造價高，施工時間長。但是聚氨酯預制保溫管采用的是直埋式敷設方式，占地少，施工煩瑣快捷，而且有利于環(huán)境的維護。
The third aspect is from the laying way. Traditional heat preservation pipes are laid by trench and overhead, which have high cost and long construction time. However, polyurethane prefabricated insulation pipes are laid directly, occupying less land, construction is tedious and fast, and is conducive to the maintenance of the environment.
聚氨酯發(fā)泡保溫管由于聚氨酯硬質泡沫保溫層嚴密地粘結在鋼管外皮,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，高度聚乙烯外殼,玻璃鋼外殼均具有良好的防腐,絕緣和機械性能。只需管道內(nèi)部水質處置好,據(jù)國外材料引見,預制聚氨酯直埋保溫管的運用壽命可達50年以上,比傳統(tǒng)的地溝敷設,架空敷設運用壽命高3~4倍。
The polyurethane foam insulation pipe is tightly adhered to the outer skin of the steel pipe because of the rigid polyurethane foam insulation layer, which can isolate the infiltration of air and water, and can play a good anti-corrosive effect. At the same time, its foaming holes are closed, water absorption is very small, high polyethylene shell, FRP shell has good anti-corrosion, insulation and mechanical properties. According to foreign materials, the service life of prefabricated polyurethane direct-buried insulation pipe can reach more than 50 years, which is 3-4 times longer than that of traditional trench laying and overhead laying.
