2. Low heat loss, energy saving.
3. It has good anti-corrosion and insulation performance and a long service life.
4. It occupies less land, has a fast construction speed and is beneficial to environmental protection.
5. Safety.

High-density polyethylene plastic outer protective polyurethane foam precast directly buried insulation pipes are highly favored by people due to their excellent performance, convenient construction and long service life (30 to 50 years). Its structure consists of three parts: outer protective layer, insulation layer and anti-seepage layer. The material of the outer protective layer can be polyethylene jacket pipe, fiberglass reinforced plastic or other materials. There are three laying methods: direct burial, overhead and trench.
