Insulated Pipe - Features

1. Strong corrosion resistance and waterproof capability, with low overall costs.
According to estimates by relevant departments, dual-pipe heating systems generally reduce project costs by around 25% (when using fiberglass as the protective layer) and approximately 10% (when using high-density polyethylene as the protective layer).

2. Low heat loss, energy-saving. Heat loss is only 25% of traditional pipe materials.
Direct-buried insulated pipes have a thermal conductivity of 0.022 kcal/m.h.℃ and a water absorption rate of 0.03 kg/cm³.

3. Long service life.
Proper installation and use can extend the network's lifespan to 30-50 years, with minimal maintenance costs.

4. Minimal land occupation, fast construction, beneficial for environmental protection.
Can reduce excavation volume by over 50% and decrease the amount of masonry and concrete used by 90%.
