黄夹克保温钢管原材主要包括有缝钢管和无缝钢管。黄夹克聚氨酯保温钢管常用的保温资料是硬质聚氨脂泡沫塑料，适用温度为－185～120℃。这种资料质地松软，为进步其强度，在隔热层外面加敷一层高密度聚乙烯层，构成复合资料构造，以避免公开水渗入保温层内。黄夹克保温管构造主要包括工作钢管层，聚氨酯保温层和高密度聚乙烯维护层。其中外面的一层由预制成一定壁厚的黑色或黄色聚乙烯塑料资料掩盖。黑色的称之为黑夹克保温管，黄色的称之为黄夹克保温管。其作用一是维护聚氨酯保温层免遭机械硬物毁坏，二是防腐、防水。
The raw materials of yellow jacket insulation steel pipe mainly include seamless steel pipe and seamless steel pipe. The commonly used heat preservation material of yellow jacket polyurethane heat preservation pipe is rigid polyurethane foam plastics, the applicable temperature is - 185 - 120 C. In order to improve its strength, a layer of high density polyethylene (HDPE) is added outside the insulation layer to form a composite data structure to avoid the infiltration of open water into the insulation layer. Yellow jacket insulation pipe structure mainly includes working steel pipe layer, polyurethane insulation layer and high density polyethylene maintenance layer. One of the outer layers is covered by black or yellow polyethylene plastic materials prefabricated to a certain wall thickness. Black jacket insulation pipe is called black jacket insulation pipe, yellow jacket insulation pipe is called yellow jacket insulation pipe. Its function is to maintain the polyurethane insulation layer from the destruction of mechanical hard objects, and the second is anti-corrosion and waterproof.
黄夹克聚氨酯发泡保温管泡沫具有良好的机械性能和绝热聚氨酯保温管应用：聚氨酯保温管用于室内外各种管道，集中供热管道，空调管道、化工、等工业管道的保温、保冷工程。概述?聚氨酯发泡保温管自三十年代聚氨酯合成资料降生以来，不断作为一种优良的绝热保温资料而得到疾速开展，其应用范围也越来越普遍，更由于其施工烦琐、防腐效果显著而被大量地用于各种供热、制冷、输油、输汽等各种管道。
The yellow jacket polyurethane foam insulation tube foam has good mechanical properties and insulation polyurethane insulation pipe application: polyurethane insulation pipe for indoor and outdoor pipes, central heating pipes, central air-conditioning pipe, chemical industry, and other industrial pipelines insulation and cold insulation works. Overview? Polyurethane foamed insulation pipe has been developed rapidly as an excellent thermal insulation material since the birth of polyurethane synthetic data in the 1930s, and its application scope is becoming more and more widespread. It is also widely used in various heating, refrigeration, oil transportation, steam transportation and other pipelines because of its cumbersome construction and remarkable energy-saving and anticorrosive effect.
黄夹克保温钢管直埋预制保温管由保送介质的钢管，聚氨酯硬质泡沫保温层和高密度聚乙烯外套管严密分离而成，该产品主要用于城镇集中供热管网，石油保送管线，高寒地域输水管线及厂区工业管道工程，它具有保温、防水防腐和施工烦琐，不怕植物根刺的优点，施工不需地沟敷设，能在0.6-1.2米冻土层内直埋，热损失比传统工艺可降低40%，运用寿命比其他绝热防腐资料进步3-5倍以上，运用寿命可达30-50年。
The Yellow lined thermal insulation steel pipe directly buried prefabricated heat preservation pipe is made up of the steel pipe, the polyurethane rigid foam insulation layer and the high-density polyethylene sheath pipe. The product is mainly used in the urban central heating network, the petroleum delivery pipeline, the cold water pipeline and the industrial pipeline project. It has the characteristics of high efficiency insulation, waterproof, antisepsis and construction, and is not afraid of plant root thorn. Advantages: construction without trench laying, can be directly buried in 0.6-1.2 meters of frozen soil layer, heat loss can be reduced by 40% compared with traditional technology, service life is more than 3-5 times higher than other insulation and anti-corrosion materials, and service life can reach 30-50 years.
