1、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。
1. Polyurethane direct-buried insulation pipe has good thermal insulation performance, and its heat loss is only 25% of the traditional pipe material. Long-term operation can save a lot of energy and significantly reduce energy costs.
2、具有很强的防水和耐腐蚀才能,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。
2. It has strong ability of waterproofing and corrosion resistance. It can be directly buried in open or water without installing pipe trenches. The construction is tedious and fast, and the comprehensive cost is low.
3、在低温条件下也具有良好的耐腐蚀和耐冲击性,可直接埋入公开冻土。
3. It also has good corrosion resistance and impact resistance at low temperature, and can be directly buried in open frozen soil.

4、运用寿命可达30-50年,正确的装置和运用可使管网维修费用极低。
4. The service life can reach 30-50 years. Correct installation and operation can make the maintenance cost of the pipeline network very low.
5、运用寿命可达30-50年。管径:DN15--DN600 厚度:15--50mm 用处:集中供热管道、制冷管道、工业管道等。
5. The service life can reach 30-50 years. Diameter: DN15 - DN600 Thickness: 15 - 50mm Uses: Central heating pipeline, refrigeration pipeline, industrial pipeline, etc.
6、含氧指数:≥27 密度:40--70kg/立方m 憎水率:0.03kg/立方cm 导热系数:0.022kcal/m.h.℃
6. Oxygen content index: > 27 density: 40-70 kg/cubic m hydrophobicity: 0.03 kg/cubic cm thermal conductivity: 0.022 kcal/m.h.
保温管平安体系
Safety System of Insulation Pipe
除中国外消费的直埋保温管,均设有渗漏报警线,一旦管道某处发作渗漏,经过报警线的传导,便可在专用检测仪表上显现出保温管道渗水、漏水的精确位置及渗漏水平的大小,以便通知检渗人员疾速处置漏水的管段,保证供热管网的平安运转。国内消费的保温管道末设渗漏报警线,有待补上这一空白。
All direct-buried insulating pipes except those consumed in China are equipped with leakage alarm lines. Once leakage occurs somewhere in the pipeline and is transmitted by the alarm lines, the precise location and leakage level of the insulating pipes can be displayed on the special testing instruments, so as to inform the inspectors to quickly dispose of the leaking pipes and ensure the supply of water. Safe operation of heat pipe network. Leakage alarm line is installed at the end of insulation pipeline for domestic consumption, which needs to be filled in.
