HDPE Pipe Extrusion Line – Single & Multi-Layer Co-Extrusion

Product Overview

Our HDPE pipe extrusion line is a complete production system designed to manufacture high-quality HDPE pipes for a wide range of applications, including water supply, gas distribution, sewage systems, industrial piping, and more. With flexible configurations available for both single-layer and multi-layer co-extrusion, the line delivers outstanding product quality, production efficiency, and cost-effectiveness.

Single-Layer & Multi-Layer Co-Extrusion Capabilities

The extrusion line supports a variety of pipe structures to meet different application requirements and cost objectives:

Single-Layer Pipe – Standard configuration for straightforward applications using a single material formulation.

Multi-Layer Co-Extrusion – Available in structures such as ABA, ABCBA, and other custom configurations. By using different materials for the inner and outer layers, manufacturers can:

Incorporate Recycled Materials – Utilize post-industrial or post-consumer recycled HDPE in the inner layer, where it does not affect pipe surface quality or performance.

Maintain High Quality – Keep premium virgin materials in the outer layer for excellent appearance, UV resistance, and environmental stress crack resistance.

Reduce Material Costs – Significantly lower production costs by replacing a portion of virgin material with recycled or lower-cost alternatives, without sacrificing pipe strength or durability.

Enhance Performance – Combine different materials to achieve specific properties, such as improved chemical resistance, higher pressure ratings, or better flexibility.

Common multi-layer structures include:

Structure Description ABA Outer and inner layers are the same material (e.g., virgin HDPE), middle layer is a different material (e.g., recycled HDPE or lower-cost resin) ABCBA Symmetrical five-layer structure offering enhanced performance and cost optimization options Equipment Configuration

The HDPE pipe extrusion line consists of the following core components:

Extruder – High-performance single-screw extruder optimized for HDPE and other polyolefin materials

Multi-Layer Co-Extrusion Die – Precision spiral die design for uniform melt distribution in single or multiple layers

Vacuum Calibration Tank – Ensures precise pipe diameter and roundness through vacuum sizing

Multi-Stage Spray Cooling Tank – Provides efficient and uniform cooling to maintain pipe dimensional stability

Haul-Off Machine – Smooth and consistent pipe pulling with precise speed control

Cutter or Winder – Planetary cutter for rigid pipe applications, or in-line winder for coil packaging

PLC Control System – Centralized control with touchscreen interface for full process management

Key Advantages

Cost-Effective Multi-Layer Production – The ability to use recycled or lower-cost materials in the inner layers significantly reduces material costs while maintaining the high quality and performance required for demanding applications.

Perfect for Recycled Material Integration – Our multi-layer technology is ideal for recyclers and pipe manufacturers looking to incorporate recycled HDPE into their products, supporting sustainability goals without compromising pipe quality.

Intelligent Control – PLC system with real-time monitoring of current, pressure, and energy consumption, plus per-ton electricity cost tracking for precise production cost management.

User-Friendly Operation – One-touch start/stop and intuitive interface reduce operator workload and minimize the risk of human error.

Flexible and Scalable – Configurations available for pipe diameters ranging from small-diameter tubing to large-diameter industrial pipes.

Proven Reliability – Built with heavy-duty components for 24/7 continuous production in demanding industrial environments.
