The polyurethane spray-applied, polyethylene winding pre-insulated pipe production line, independently developed by Qingdao Huashida Machinery Co., Ltd., integrates three core systems: an external shot blasting and derusting unit, a polyurethane spraying system, and a PE winding unit. This advanced production line has obtained multiple national patents and has been evaluated by third-party authorities with a technology advancement rating of Level 5, positioning it at the forefront of domestic innovation. It has also been recognized as a "First Set of Technical Equipment" in Shandong Province. The system utilizes a continuous spraying production process, ensuring a high degree of automation and superior production efficiency. It optimizes raw material usage while achieving enhanced foaming performance and a high closed-cell rate, resulting in reduced water absorption and improved insulation properties. With its integrated "three-in-one" molding process, the production line delivers highly reliable and consistent product quality. Furthermore, its low-carbon and environmentally friendly design contributes to both strong economic returns and significant social benefits.
Producing technology flow of the polyurethane coating steel preinsulated pipe equipment:
1. Remove rust from steel pipe surface by shot-blasting machinery.
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 edges.
