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. 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. It also has good corrosion resistance and impact resistance at low temperature, and can be directly buried in open frozen soil.

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. The service life can reach 30-50 years. Diameter: DN15 - DN600 Thickness: 15 - 50mm Uses: Central heating pipeline, refrigeration pipeline, industrial pipeline, etc.

6. Oxygen content index: > 27 density: 40-70 kg/cubic m hydrophobicity: 0.03 kg/cubic cm thermal conductivity: 0.022 kcal/m.h.

Safety System of Insulation Pipe

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.
