PU Spray Foaming Preinsulated Pipe Production Line

DETAILS

The "polyurethane sprayed polyethylene wrapped prefabricated buried insulation pipe" consists of a working steel pipe, a sprayed polyurethane insulation layer, and an extruded polyethylene outer protective layer. The thickness of the insulation layer and the outer protective layer can be adjusted within a certain range as needed during production. Quantitative production can be carried out based on the parameters of the medium used in centralized heating and cooling, as well as the required insulation layer thickness for actual heat dissipation losses, to meet the needs of different projects.

Technical parameter

Advantages of spray coating and winding process polyurethane insulation pipe products

1. Improved the mechanical properties of the outer protective tube.

2. Reduced the wall thickness of the outer protective tube.

3. Reduced the water absorption rate of the insulation layer.

4. Improved the closed cell rate of the insulation layer.

5. Reduced the eccentricity of the insulation pipe axis.

6. Improved the uniformity of the overall insulation layer density of the pipeline.

7. Improved the compressive strength of the insulation layer.

8. Reduce the thermal conductivity of the insulation layer and minimize energy loss.
