110-630 Three Layers PE Pipe Extrusion Line
110–630mm Three‑Layer PE Pipe Extrusion Line – Heavy‑Duty Multi‑Layer Co‑Extrusion System for Large‑Diameter PE Pipes
High‑Performance Manufacturing Solution for Municipal Water, Gas & Industrial Pipeline Projects
Our 110–630mm Three‑Layer PE Pipe Extrusion Line is a heavy‑duty co‑extrusion system engineered for the production of multi‑layer polyethylene (PE) pipes used in large‑scale municipal water supply networks, natural gas distribution systems, industrial effluent transport, and irrigation mainlines. Covering the critical diameter range from 110mm up to 630mm, this production line is the ideal choice for manufacturers supplying high‑volume pipeline projects that demand superior mechanical strength, excellent crack resistance, and long‑term reliability.
Built with dedicated high‑torque extruders, precision co‑extrusion die heads, advanced vacuum calibration technology, and fully integrated PLC automation, this line ensures exceptional interlayer bonding, outstanding dimensional accuracy, and robust 24/7 continuous operation – even under the most demanding production environments.
Why Choose Our 110–630mm Three‑Layer PE Pipe Extrusion Line?
- Advanced Three‑Layer Co‑Extrusion Technology
Producing multi‑layer PE pipes at these diameters requires sophisticated engineering. Our line features three dedicated single‑screw extruders – one for the inner layer, one for the core layer (which can be formulated with up to 30% recycled material or mineral fillers for enhanced stiffness), and one for the outer layer. The precision‑engineered co‑extrusion die head ensures perfectly uniform layer thickness and superior interlayer adhesion, delivering pipes with ABA or ABC layer configurations that meet the most stringent quality requirements. - High‑Torque Dual‑Drive Extruder Configuration
To achieve the necessary extrusion pressure and high output for large‑diameter pipes, the line is equipped with high‑torque single‑screw extruders with optional dual‑motor gearboxes. This configuration delivers outputs of up to 800–1200+ kg/h, maximising production efficiency for large‑scale pipeline projects while ensuring consistent melt quality and stable pressure profiles. - Superior Melt Homogeneity & Layer Uniformity
Large‑diameter multi‑layer pipes require precise control over each layer's thickness distribution to prevent weld‑line defects and delamination. Our line incorporates specially designed spiral mandrel die heads with optimised flow channels that ensure even melt distribution across the entire pipe circumference. Paired with barrier‑type screws featuring optimal L/D ratios (up to 33:1), this technology guarantees excellent homogenisation and minimises wall thickness variation, producing pipes with consistent quality from batch to batch. - Robust Vacuum Calibration & Intensive Multi‑Stage Cooling
The line features an extended vacuum calibration tank with enhanced suction capacity and high‑efficiency water circulation, followed by 3–5 multi‑stage spray cooling tanks. This ensures rapid, even solidification across the entire pipe surface, strictly controlling outer diameter tolerances (to ±0.2mm) and maintaining excellent pipe ovality in compliance with ISO 4427, EN 12201, and ASTM F714 standards. - Material Optimisation & Cost Efficiency
The three‑layer design allows manufacturers to significantly reduce production costs by incorporating up to 30% recycled or lower‑grade PE material in the middle core layer, while maintaining high‑quality virgin material for both inner and outer layers. This innovative approach not only lowers raw material expenses but also supports sustainable manufacturing practices – a key competitive advantage in today's market. - Fully Automated PLC Control with Industry 4.0 Readiness
Integrated with a Siemens PLC control system and large‑format touch‑screen HMI, the line offers full automation of extrusion parameters, including melt temperature, screw speed, haul‑off force, and layer thickness monitoring (with optional online ultrasonic wall thickness gauges). Real‑time data acquisition, recipe management, and fault diagnostics ensure consistent quality and minimise production downtime. The system is also compatible with remote monitoring and Industry 4.0 integration.
Main Production Line Components
For heavy‑duty multi‑layer production at these diameters, the system comprises the following core units:
Component Function
High‑Torque Single‑Screw Extruder (Inner Layer)： Provides high‑capacity plasticisation and consistent melt delivery for the inner A layer
High‑Torque Single‑Screw Extruder (Core Layer) ： Handles recycled material or filled compounds for the middle layer, reducing costs
High‑Torque Single‑Screw Extruder (Outer Layer)： Delivers high‑quality virgin PE for the outer A layer, ensuring UV resistance and surface finish
Precision Co‑Extrusion Die Head (spiral mandrel type)： Ensures uniform layer distribution and superior interlayer bonding for 110–630mm pipes
Extra‑Length Vacuum Calibration Tank： Precisely sizes the pipe while preventing deformation and maintaining roundness
Multi‑Stage Spray Cooling Tanks (3–5 sections)： Rapidly cools and solidifies the large‑diameter pipe for high‑speed production
Heavy‑Duty Caterpillar Haul‑Off Unit (multi‑track, high clamping force)： Provides stable, non‑slip traction without deforming the pipe surface
Automatic Planetary Cutter (with carbide blades) ： Precision cutting to preset lengths with smooth, burr‑free ends
Auto Tipping / Stacking Rack (with hydraulic lifting mechanism) ： Safely collects and stacks finished large‑diameter pipes for efficient packaging and transport
Typical Applications- Municipal potable water transmission mains – large‑diameter distribution networks
- Natural gas and LNG distribution pipelines – medium‑pressure gas transport
- Sewage and stormwater drainage systems – large‑bore gravity and low‑pressure lines
- Industrial effluent and chemical transport – corrosion‑resistant applications
- Irrigation mainlines – large‑scale agricultural and agricultural mega‑projects
- Mining and slurry transport pipelines – abrasive‑resistant applications (with appropriate additives)
