聚氨酯直埋保溫管與傳統(tǒng)保溫管的區(qū)別
The difference between polyurethane direct-buried insulating pipe and traditional insulating pipe
聚氨酯直埋保溫管的目的概括性的解釋有兩個
There are two general explanations for the purpose of polyurethane directly buried insulating pipes.
一是：保證管道能在地下臨時波動運(yùn)轉(zhuǎn)
One is to ensure that the pipeline can operate temporarily in underground fluctuations.
二是：保證保溫管能起到良好的保溫效果，不糜費(fèi)動力，不毀壞園林綠化。
Second, to ensure that the insulation pipe can play a good thermal insulation effect, do not waste power, do not destroy garden greening.
聚氨酯直埋保溫管的使用越來越普遍，隨著社會的提高和科技的開展，各式各樣的夾克保溫管間接而出，進(jìn)而產(chǎn)品的品種也就越來越什麼樣的都有了。地埋聚氨酯直埋保溫管保溫功能好，熱損失僅爲(wèi)傳統(tǒng)管材的25%，臨時運(yùn)轉(zhuǎn)可浪費(fèi)少量動力，明顯降低動力本錢。其施工簡便，防腐效果明顯而被少量地用于各種供熱，制冷，輸油，化工等工業(yè)管道的保溫。
With the improvement of society and the development of science and technology, various kinds of jacket insulation pipes come out indirectly, and the variety of products is more and more different. Buried polyurethane direct-buried insulation pipe has good thermal insulation function, and its heat loss is only 25% of the traditional pipe material. Temporary operation can waste a small amount of power and obviously reduce the power cost. The utility model has the advantages of simple construction, obvious energy saving and anticorrosion effect, and is used in a small amount for heat preservation of various industrial pipes such as heating, refrigeration, oil transportation, chemical industry, etc.
一個方面是在保溫管的構(gòu)造和功能。聚氨酯預(yù)制保溫管的構(gòu)造采用由里到外順次有內(nèi)維護(hù)層、保溫層、外維護(hù)層。內(nèi)維護(hù)層是保送介質(zhì)的鋼管，具有耐腐蝕性和防水功能好等特點。鋼管和外維護(hù)層之間的硬質(zhì)聚氨酯泡沫保溫層采用管中管發(fā)泡技術(shù)使三者嚴(yán)密結(jié)合而成。外維護(hù)層是高密度聚乙烯外套管?？偟恼f來，聚氨酯預(yù)制保溫管的保溫隔熱功能比傳統(tǒng)保溫管愈加優(yōu)良，保溫保冷的效果更好。
The first aspect is the structure and function 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 function. The rigid polyurethane foam insulation layer between the steel tube and the outer maintenance layer is made up of three pipes by foam tube technology. The outer maintenance layer is the high density polyethylene outer casing. Generally speaking, the thermal insulation function 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(fèi)方面。聚氨酯預(yù)制保溫管采用的事后訂制，它愈加有利于保溫管使用的實踐消費(fèi)生活中，具有很大的靈敏性和順應(yīng)性，可以依據(jù)不同需求，設(shè)計不同參數(shù)的直埋保溫管。
The second aspect is industrial consumption. Polyurethane prefabricated insulating pipes are customized afterwards. It is more conducive to the practical consumption of insulating pipes. It has great sensitivity and compliance. It can design directly buried insulating pipes with different parameters according to different needs.
第三個方面從敷設(shè)方式來看。傳統(tǒng)保溫管采用的是地溝及架空的敷設(shè)方式，工程造價高，施工工夫長。但是聚氨酯預(yù)制保溫管采用的是直埋式敷設(shè)方式，占地少，施工簡便快捷，而且有利于環(huán)境的維護(hù)。
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, which occupies less land, is simple and fast to construct, 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(zhì)泡沫保溫層嚴(yán)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，高度聚乙烯外殼,玻璃鋼外殼均具有良好的防腐,絕緣和機(jī)械功能。
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 functions.
