Land directly buried pre-insulated thermal insulation pipe

The direct-buried pre-insulated insulating pipe consists of running pipe, insulating layer and outer protective layer (PE pipe, FRP pipe and iron pipe). Over the past decade, the practice has proved that the direct-buried pre-insulated insulation pipe has outstanding advantages over the traditional trench and overhead insulation pipe.

1. Long service life, up to 30-50 years, low maintenance costs.

2. The heat preservation performance is good, and the heat loss is only 25% of the traditional heat preservation.

3. It has good corrosion resistance, impact resistance and strong waterproofing.

4. Convenient construction and low comprehensive cost.
