黑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。聚氨酯发泡保温管自三十年代聚氨酯合成材料降生以来，不时作为一种优良的绝热保温材料而得到疾速展开，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。大量地用于各种供热、制冷、输油、输汽等各种管道。
Black 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 pipeline insulation and cold insulation works. Since the birth of polyurethane synthetic material in the 1930s, polyurethane foamed insulation pipe has been rapidly developed as an excellent thermal insulation material, and its application scope is becoming more and more widespread. It is also widely used in various heating, refrigeration, oil and steam transmission pipelines because of its cumbersome construction and remarkable energy-saving and anti-corrosion effect. It is widely used in various heating, refrigeration, oil and steam pipelines.
钢管的选用：
Selection of steel pipe:
根据设计和客户的恳求普通为：DN200以下选用无缝管，以上选用螺旋焊管和直缝焊管。钢管表面经过的抛除锈工艺处置后，钢管除锈等级可达标准中的Sa2级，表面粗糙度可达标准中R=12.5微米
According to the design and customer's request, the seamless pipe is usually chosen below DN200, and the spiral welded pipe and the straight welded pipe are selected above. After the surface of steel tube is treated by advanced rust removal technology, the grade of steel tube rust removal can reach Sa2 level in the standard, and the surface roughness can reach R=12.5 micron in the standard.
性能特性：
Performance characteristics:
1、运用了导热系数低、隔热性能好的硬质聚氨酯作为隔热材料，具有优良的隔热性。
1. Using rigid polyurethane with low thermal conductivity and good thermal insulation as heat insulation material, it has excellent thermal insulation.
2、正常运转后130℃的水保送到40以外时，降温仅为1℃左右。
2. When the water conservation at 130 C is delivered to 40 kilometers away after normal operation, the cooling rate is only about 1 C.
3、有很强的防水和耐腐蚀才干，不需附设管沟，可直接埋入公开或水中，施工烦琐疾速，综合造价低。
3. Strong ability of waterproof and corrosion resistance. It can be directly buried in open or water without additional pipe trenches. The construction is tedious and fast, and the comprehensive cost is low.
4、在低温条件下也具有良好的耐腐蚀和耐冲击性，可直接埋入冻土层。
4. It also has good corrosion resistance and impact resistance at low temperature, and can be directly buried in frozen soil.
5、预制保温管运用了耐腐蚀性的(HDPE：高密度聚乙烯)外套管，不受生物和化学腐蚀的影响。
5. Prefabricated insulating pipes use corrosion-resistant (HDPE: HDPE) outer casing, which is not affected by biological and chemical corrosion.
6、可根据用户需求提供口径之间各种管径及保温厚度的管材和相配套的管件(弯头、三通、变径管、固定节等)
6. Pipes with various diameters and insulation thicknesses and matching fittings (elbows, tees, variable diameter pipes, fixed joints, etc.) can be provided according to user's requirements.
7、产品执行中华人民共和国城镇树立行业标准。
7. Implementing products to establish industry standards in cities and towns of the People's Republic of China.
8、为确保预制直埋保温管三位一体，发泡前钢管外表面处置，塑料管内表面电晕处置，其中除锈等级抵达中Sa2.5的规则，外壳管内表面张力抵达50达因/厘米。
8. In order to ensure the trinity of prefabricated directly buried insulating pipes, the outer surface of steel pipes before foaming and the inner surface corona of plastic pipes are disposed. Among them, the rule of Sa2.5 in the rust removal grade is reached, and the inner surface tension of the outer pipes reaches 50 dynes/cm.
9、聚乙烯外护管采用高密度聚乙烯材料，辅以抗氧剂等各种助剂制成，并对原材料和产质量量中止严厉检验，确保产质量量抵达标准和直埋管外护管的技术恳求，进步了外护管的整体质量。细致技术指标见下表。
9. Polyethylene external protective pipe is made of high density polyethylene (HDPE) material, supplemented by various additives such as antioxidants. Strict inspection of raw materials and quality of production is stopped to ensure that the quality of production reaches the standard and the technical appeal of directly buried external protective pipe improves the overall quality of external protective pipe. Detailed technical indicators are shown in the table below.
10、公司配备有进口和国产高压发泡机、液压穿管机，进步了产品的整体质量。
10. The company is equipped with imported and domestic high-pressure foaming machine and hydraulic pipe-piercing machine, which improves the overall quality of products.
