PU Sprayed Foaming HDPE Winding Preinsulation Pipe Manufacturing System
Pipe diameter range: 500-1600MM
Polyurethane spraying polyethylene wrapping 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.
Main features of the PU 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.

Rust Removal
First, the surface of the steel pipe is derusted, usually by shot blasting or sand blasting, to ensure that the surface is clean and free of rust, oil and other impurities. Preheating: The cleaned steel pipe is preheated so that the subsequent polyurethane foam can better adhere to the steel pipe surface.
Polyurethane spray molding line
The polyurethane raw materials (isocyanate and polyol) are mixed in a high-pressure foaming machine and evenly sprayed onto the surface of the preheated steel pipe. The polyurethane raw materials rapidly foam on the surface of the steel pipe, forming an insulating layer.
Polyethylene sheet extruding winding line
Polyethylene (PE) is wrapped around the polyurethane insulation layer to form an outer sheath. Cooling and shaping: The wrapped pipe is cooled and shaped to ensure that the outer sheath and insulation layer are tightly bonded to form a stable structure.
