聚氨酯发泡保温钢管的保温性能好,热损失仅为传统管材的25%,长期运行可节约大量能源,显著降低能源成本.
The heat loss of polyurethane foam insulation steel pipe is only 25% of that of traditional pipe material. Long term operation can save a lot of energy and significantly reduce energy cost
聚氨酯发泡保温钢管具有很强的防水和耐腐蚀能力,不需附设管沟,可直接埋入地下或水中,施工简便迅速,综合造价低。
Polyurethane foam thermal insulation steel pipe has strong water-proof and corrosion-resistant ability. It can be directly buried in the ground or water without the pipe trench. The construction is simple and rapid, and the comprehensive cost is low.
聚氨酯发泡保温钢管在低温条件下也具有良好的耐腐蚀和耐冲击性,可直接埋入地下冻土。
Polyurethane foam insulation steel pipe also has good corrosion resistance and impact resistance at low temperature, which can be directly buried in the frozen soil.
正确的安装和使用聚氨酯发泡保温钢管可使管网维修费用低。
The correct installation and use of polyurethane foam insulation steel pipe can reduce the maintenance cost of pipe network.
聚氨酯防腐保温钢管可设置报警系统,自动检测管网渗漏故障,准确指示故障位置并自动报警。
The alarm system can be set up for polyurethane anticorrosive and thermal insulation steel pipe, which can automatically detect the leakage fault of pipe network, accurately indicate the fault location and automatically alarm.

聚氨酯发泡保温螺旋钢管的这种防腐保温方式可以架空或者埋在地下,整个施工过程均可在现场进行,便于施工和操作,而且很容易被施工人员操控,流程比较简单。
The anti-corrosion and thermal insulation method of polyurethane foam insulation spiral steel pipe can be overhead or buried underground, and the whole construction process can be carried out on site, which is convenient for construction and operation, and is easy to be controlled by construction personnel, and the process is relatively simple.
聚氨酯硬泡材料孔隙率结构稳定,基本上是闭孔,如此不仅保温性能优良,而且抗冻融、吸声性也好。
The porosity structure of rigid polyurethane foam material is stable and basically closed, which not only has excellent heat preservation performance, but also has good freeze-thaw resistance and sound absorption.
现场模浇聚氨酯硬泡保温构造的平均寿命在正常使用与维修的条件下,能达到25年以上。
Under the condition of normal use and maintenance, the average life of cast-in-situ polyurethane rigid foam insulation structure can reach more than 25 years.
现场模浇聚氨酯硬泡保温体系的各种组成材料,具有化学与物理的稳定性。
All kinds of component materials of polyurethane rigid foam insulation system have chemical and physical stability.
地埋式聚氨酯保温钢管技术标准:
Technical standard for buried polyurethane insulation steel pipe:
《高密度聚乙烯外护管硬质聚氨酯泡沫塑料预制直埋保温管及管件》GB/T 29047-2012《城镇供热预制直埋保温管道技术指标检测方法》GB/T 29046-2012
"High density polyethylene external protective tube rigid polyurethane foam prefabricated directly buried insulation pipe and fittings" GB/T 29047-2012 "urban heating prefabricated directly buried insulation pipe technical index detection method" GB/T 29046-2012
聚氨酯供暖防腐保温管是什么
What is polyurethane heat preservation pipe
热力聚氨酯直埋保温管道主要由三层结构构成,一层以高密度聚乙烯或玻璃钢做成的保护壳,一层采用硬质聚氨酯泡沫塑料做成的保温层,还有一层工作钢管,工作钢管可以根据介质输送要求的不同分别采用有缝钢管、无缝钢管、双面埋弧螺旋焊接钢管。
The thermal polyurethane direct buried thermal insulation pipeline is mainly composed of three layers of structure, one is a protective shell made of high-density polyethylene or fiberglass reinforced plastics, one is a thermal insulation layer made of rigid polyurethane foam, and one is a working steel pipe. The working steel pipe can adopt seamless steel pipe, seamless steel pipe and double-sided submerged arc welded pipe separately according to the requirements of medium transportation.

聚氨酯保温无缝钢管现场接头保温须在试验压力合格后进行。
The field joint insulation of polyurethane insulation seamless steel pipe must be carried out after the test pressure is qualified.
这一项工作是聚氨酯直埋保温管施工必要的。施工质量直接影响使用寿命。保温层有现场发泡施工和保温瓦施工两种方法.无论采用哪种方法,都不能出现环形空间、开裂、脱层等缺点。
This work is necessary for the construction of polyurethane directly buried insulation pipe. The construction quality directly affects the service life. There are two methods of foam construction and insulation tile construction for insulation layer. No matter which method is adopted, the defects such as annular space, cracking and delamination can not appear.
维护层的做法有多种,但要保证接头的整体性和严密性。
There are many methods for maintenance layer, but the integrity and tightness of joints should be ensured.
