聚氨酯直埋保温管与传统保温管性能对比

来源:http://www.rrhsf.com 日期:2019-04-04 发布人:admin
管道直埋敷设技术在国内的开展曾经有几十年,聚氨酯直埋保温管的目的概括性的解释有两个:一是:保证管道能在公开长期稳定运转;二是:保证保温管能起到良好的保温效果,不糜费能源,不毁坏园林绿化。
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.
聚氨酯直埋保温管的应用越来越普遍,随着社会的进步和科技的开展,形形色色的夹克保温管直接而出,进而产品的品种也就越来越什么样的都有了。地埋聚氨酯直埋保温管保温性能好,热损失仅为传统管材的25%,长期运转可节约大量能源,显著降低能源本钱。其施工烦琐,节能防腐效果显著而被大量地用于各种供热,制冷,输油,化工等工业管道的保温。
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.
个方面是在保温管的构造和性能。聚氨酯预制保温管的构造采用由里到外依次有内维护层、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性能好等特性。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分离而成。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性能比传统保温管愈加优良,保温保冷的效果更好。

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.
第二个方面是工业消费方面。聚氨酯预制保温管采用的预先订制,它愈加有利于保温管应用的实践消费生活中,具有很大的灵敏性和顺应性,能够依据不同需求,设计不同参数的直埋保温管。
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,施工时间长。但是聚氨酯预制保温管采用的是直埋式敷设方式,占地少,施工烦琐快捷,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, occupying less land, construction is tedious and fast, 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,绝缘和机械性能。只需管道内部水质处置好,据国外材料引见,预制聚氨酯直埋保温管的运用寿命可达50年以上,比传统的地沟敷设,架空敷设运用寿命高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.
