Durable Polyurethane PU Spraying Foam Pre-Insulated Pipe Production Line

Product Description

The polyurethane sprayed polyethylene thermal winding preinsulation pipe production line, independently developed by Huashida, is composed of three main sections: the external shot blasting and derusting collector production line, the polyurethane spraying production line, and the PE winding production line. This production line holds numerous national patents and has been rated as having a technology advanced level of 5 by a third-party standardized evaluation, indicating that it has reached the domestic leading level. It has also been awarded the first set of technical equipment in Shandong Province.

Producing technology flow of the polyurethane coating steel preinsulated pipe equipment:

1. Remove rust from steel pipe surface
2. preheat the steel pipe to get it ready for polyurethane spraying
3. Spray polyurethane evenly on steel pipe outer surface
4. Wrap melted HDPE strap around the PU foam
5. Trim the pipe ends

Technical Features:
1. Dust removal meets environmental standards(The three-level dust removal )
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
