聚氨酯直埋保温管与传统保温管的区别
The difference between polyurethane direct-buried insulating pipe and traditional insulating pipe
聚氨酯直埋保温管的目的概括性的解释有两个
There are two general explanations for the purpose of polyurethane directly buried insulating pipes.
一是：保证管道能在地下临时波动运转
One is to ensure that the pipeline can operate temporarily in underground fluctuations.
二是：保证保温管能起到良好的保温效果，不糜费动力，不毁坏园林绿化。
Second, to ensure that the insulation pipe can play a good thermal insulation effect, do not waste power, do not destroy garden greening.
聚氨酯直埋保温管的使用越来越普遍，随着社会的提高和科技的开展，各式各样的夹克保温管间接而出，进而产品的品种也就越来越什麼样的都有了。地埋聚氨酯直埋保温管保温功能好，热损失仅爲传统管材的25%，临时运转可浪费少量动力，明显降低动力本钱。其施工简便，节能防腐效果明显而被少量地用于各种供热，制冷，输油，化工等工业管道的保温。
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.
一个方面是在保温管的构造和功能。聚氨酯预制保温管的构造采用由里到外顺次有内维护层、保温层、外维护层。内维护层是保送介质的钢管，具有耐腐蚀性和防水功能好等特点。钢管和外维护层之间的硬质聚氨酯泡沫保温层采用管中管发泡技术使三者严密结合而成。外维护层是高密度聚乙烯外套管。总的说来，聚氨酯预制保温管的保温隔热功能比传统保温管愈加优良，保温保冷的效果更好。
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.
第二个方面是工业消费方面。聚氨酯预制保温管采用的事后订制，它愈加有利于保温管使用的实践消费生活中，具有很大的灵敏性和顺应性，可以依据不同需求，设计不同参数的直埋保温管。
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.
第三个方面从敷设方式来看。传统保温管采用的是地沟及架空的敷设方式，工程造价高，施工工夫长。但是聚氨酯预制保温管采用的是直埋式敷设方式，占地少，施工简便快捷，而且有利于环境的维护。
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.
聚氨酯发泡保温管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。
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.
