Description

Rigid Polyurethane Spray & HDPE Winding Directly Buried Insulation Pipe Manufacturing Line

Product Description

Pipe Diameter Range: 500-1600mm


The PU spray foaming HDPE wrapping pre-insulated pipe production line is specially designed for manufacturing polyurethane pre-insulated direct buried pipes. These pipes are widely used in district heating networks, cooling systems, and crude oil transportation projects.
The line includes pipe pre-treatment, spray foaming, HDPE winding, cutting, testing, and finished product handling, realizing fully automatic continuous production.Applicable for various pipe diameters and insulation thicknesses, meeting the production needs of different specifications of pre-insulated pipes.


Features
1. Dust removal meets environmental standards
2. Suitable for the production of large-diameter insulation pipes
3. Automated operation of production lines
4. Spraying saves materials
5. Efficient extrusion of pipelines
6. Automated precision machining of pipeline interfaces


Application

District heating pipelines, urban central heating projects, industrial high-temperature pipeline insulation, and other buried pipeline systems.

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.
