PU spraying PE winding pre-insulated pipe production line
PU spraying PE winding pre-insulated pipe production line is used for the production of polyurethane prefabricated direct buried thermal insulating pipes, which are widely used in the field of heating, cooling, and crude oil transportation.
The spraying and winding production process ensures the uniformity of the density of the insulation layer, improves product quality, and reduces production costs.
PUF spray PE winding preinsulated pipe production line consists of the following parts:
2) Polyurethane spray molding line
3) Polyethylene sheet extruding winding line
4) Water cooling line
5) End-cutting equipment
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:
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.
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.
