With rising demand for PE water and agricultural pipes, customer invested four LIANSU high-speed HDPE pipe co-extrusion lines to expand capacity. These three-layer HDPE pipe extrusion lines combine high-speed production with recycled material use, increasing output while keeping production costs down.

Technical Spec.

LSP-63PE Three-Layer High-Speed HDPE Pipe Co-Extrusion Line

• Pipe diameter: Ø20–Ø63 mm

• Line speed: 1.5–32 m/min

• Output: 450 kg/h

LSP-160PE Three-Layer High-Speed HDPE Pipe Co-Extrusion Line

• Pipe diameter: Ø50–Ø160 mm

• Line speed: 1.5–20 m/min

• Output: 820–870 kg/h

High-Speed Extrusion with Consistent Quality

These high-speed HDPE pipe extrusion lines feature high-efficiency 40 L/D single-screw extruders designed for high-speed PE water pipe production, delivering high output with stable melt temperatures. Spiral pipe head ensure precise layer distribution and wall thickness control, maintaining a consistent ABA structure while minimizing delamination, poor interlayer bonding, and uneven wall thickness.

Recycled Material Use & Flexible Production

Adopt an ABA three-layer structure, These high-speed HDPE pipe extrusion lines allow up to 80% recycled material in the middle layer. Screen changers filter impurities from the melt to ensure stable pipe quality during recycled HDPE pipe extrusion.

Accurate Weight Control & Production Monitoring

The granule loss-in-weight feeder integrates with the line PLC to maintain target pipe weight per meter and reduce material consumption. Weight data can be displayed on the Flexcon+ control system, which also collects production data, analyzes performance, and monitors equipment status for better production management.
