Description
PU sprayed HDPE winding preinsulation pipe continuous production line
The polyurethane sprayed polyethylene thermal winding insulation pipe production line independently developed by Huashida, consists of three parts: External shot blasting and derusting production line, polyurethane spraying production line, and PE winding production line. The line has a number of national patents, and the third-party standardized evaluation report has a technology advanced level of 5, reaching the domestic leading level. And won the first set of technical equipment in Shandong Province.The line adopts continuous spraying production process. High automatic, fast production efficiency, saving raw materials, increased foaming and closed cell rate, lower water absorption rate, trinity molding, and more reliable performance. Products with low carbon environmental protection have higher economic and social benefits.Technological 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
Composition of the polyurethane coating steel preinsulated pipe equipment:
1. Shot blasting rust removel machine
2. Medium-frequency induction heating furnace
3. Polyurethane spraying unit
4. Single screw extruder and diehead mould
5. Finished pipe ends trimming machine
6. Conveyers, racks and robotics to move and handle the pipe
7. Electrical system and PLC
