Polyurethane Spraying Foam Preinsulated Steel Pipe Making Machine High

Product Description:

The Huashida-developed polyurethane sprayed polyethylene thermal winding preinsulation pipe production line is comprised of three main parts: the external shot blasting and derusting collector production line, the polyurethane spraying production line, and the PE winding production line. This production line boasts numerous national patents and has been appraised by third-party evaluators to have an advanced technology level of 5, which is considered a leading standard in the country. It has also been recognized as the first set of technical equipment in Shandong Province.

The production line utilizes a continuous spraying process, offering high automation, rapid production efficiency, reduced raw material usage, improved foaming and closed cell rates, lower water absorption, trinity molding, and enhanced overall performance. The resulting products are characterized by their low carbon footprint and environmental friendliness, delivering both economic and social advantages.

Features:

Environmental Dust Control System
Our intelligent shot blasting system features sequential self-locking operation with variable frequency energy-saving motors. The diameter-adjustable sand volume, integrated air-wash cleaning, and quick-change specifications are complemented by three-stage dust removal that exceeds environmental standards.

Large-Diameter Pipe Production
The heavy-duty spiral conveyor enables continuous polyurethane spraying and polyethylene winding, offering high-efficiency operation with significant energy savings. This system is specially designed for large-diameter insulated pipe production while eliminating separate handling equipment needs.

Automated Production Line
Full automation is achieved through smart sensors including pipe loading/unloading detection, speed-adaptive tracking, and precision detachment confirmation systems, ensuring uninterrupted operation with minimal downtime.

Efficient Spray Application
The high-speed online spraying system maintains consistent temperature with stable medium-frequency power supply, reducing grid impact by 40%. Continuous operation with automatic pipe joining minimizes material waste while ensuring uniform coating thickness.

High-Performance Extrusion
Energy-optimized extruders with mechanical clamping deliver superior output. Automated features include triple-layer anti-corrosion cutting and touchless pipe ejection for accelerated production cycles.

Precision End Processing
Our multi-process machining center achieves tight tolerances (±0.5mm) and perfect edge finishing, consolidating multiple operations into one station for dimensional accuracy and angular precision.

This integrated system represents the next generation of insulated pipe manufacturing technology, combining environmental compliance with superior production efficiency and product consistency.
