Product structure
Rigid polyurethane spraying polyethylene winding prefabricated direct buried insulation pipe is composed of working steel pipe for conveying medium, sprayed polyurethane rigid foam insulation layer and winding polyethylene outer casing. The product structure is shown in the figure below:
![PU Spraying PE Winding Pre-Insulated Pipe Production Line]()
The scope of application of the insulation pipe
1. anti-corrosion, thermal insulation pipeline in the field of heating, cooling and crude oil transportation.
2. Medium temperature: ≤120°C (incidental peak value <140°C).
3. Medium pressure: ≤2.5MPa.
4. Laying method: It is mainly used for direct burial laying, and can also be used for trench or overhead laying of pipelines.

Advantages of Polyurethane spray insulation pipe:
1. The density of polyurethane is uniform and controllable.
2. Polyurethane rigid foam has no empty spaces.
3. The surface of polyurethane foam is rough, the shear strength (friction) to the polyethylene outer casing is greater than 200Kpa.
4. The thickness of the polyurethane insulation layer and the thickness of the polyethylene outer casing can be adjusted according to the design.
5. The production has a high degree of automation.
