Double Wall Corrugated Pipe Extrusion Lines – Heavy‑Duty Co‑Extrusion System for High‑Performance Drainage & Infrastructure Projects
Robust Manufacturing Solution for Municipal Sewage, Stormwater & Cable Protection Systems
Our Double Wall Corrugated Pipe Extrusion Lines are advanced co‑extrusion systems engineered for the production of high‑strength double‑wall corrugated (DWC) pipes used in large‑scale municipal drainage, sewage treatment, highway culverts, and cable protection infrastructure projects. Covering a wide diameter range from 63mm up to 2400mm, these production lines are the ideal choice for manufacturers supplying high‑volume underground piping systems that demand exceptional ring stiffness, lightweight construction, and long‑term durability.
Built with two dedicated high‑efficiency extruders, precision‑engineered co‑extrusion die heads, advanced water‑cooled corrugators, and fully integrated PLC automation, these lines ensure outstanding interlayer bonding, superior pipe quality, and reliable 24/7 continuous operation – even under the most demanding production conditions.
Why Choose Our Double Wall Corrugated Pipe Extrusion Lines?
- Advanced Double‑Wall Co‑Extrusion Technology
Producing double‑wall corrugated pipes requires sophisticated engineering. Our lines feature two independent single‑screw extruders – one for the smooth inner wall and one for the corrugated outer wall – with precision‑engineered co‑extrusion die heads that ensure perfectly uniform wall thickness and superior interlayer adhesion . The dual‑channel die head design allows the inner and outer layers to be produced from different materials or colours, enabling cost‑effective production with optimal material utilisation . - High‑Output Extrusion System
To achieve the necessary production capacity for large‑diameter pipes, the line is equipped wit fshh high‑speed, high‑efficiency single‑screw extruders featuring grooved feed barrels and high‑torque gearboxes . This configuration delivers outputs of up to 850–1700+ kg/h, maximising production efficiency for large‑scale projects while ensuring consistent melt quality and stable pressure profiles . - Advanced Water‑Cooled Corrugator Technology
The forming machine adopts horizontal or vertical shuttle‑type structure with closed pressure water cooling systems, dramatically improving cooling efficiency and enabling high‑speed production . The mould blocks are manufactured from special alloy aluminium through precision casting, ensuring high precision, strength, wear resistance, and excellent heat dissipation . With maximum production speeds up to 17.5 m/min, this technology significantly reduces production lead times . - Superior Pipe Quality & Structural Integrity
Double‑wall corrugated pipes produced by our lines feature a smooth inner wall for excellent flow characteristics and a trapezoidal corrugated outer wall that provides exceptional ring stiffness while maintaining lightweight construction . The special pipe wall design offers high ring stiffness, light weight, high pressure resistance, good toughness, corrosion resistance, and excellent wear resistance – making these pipes ideal for demanding infrastructure applications . - Online Belling & Socket Forming
Our lines incorporate advanced in‑line double‑layer socket forming technology, enabling the production of integrated bell‑end sockets without requiring offline processing . This significantly reduces investment costs, improves production efficiency, and ensures reliable rubber‑ring sealed joints that effectively prevent leakage and accommodate thermal expansion . - Fully Automated PLC Control
Integrated with Siemens PLC control systems and large‑format touch‑screen HMIs, the line offers full automation of extrusion parameters, including melt temperature, screw speed, haul‑off force, and production line synchronisation . Real‑time data acquisition, recipe management, and fault diagnostics ensure consistent quality and minimise production downtime. The CAN data bus technology enables comprehensive production monitoring and management .
Main Production Line Components
For heavy‑duty double‑wall production, the system comprises the following core units:
Component Function
High‑Efficiency Single‑Screw Extruder (Inner Layer): Provides high‑capacity plasticisation and consistent melt delivery for the smooth inner wall
High‑Efficiency Single‑Screw Extruder (Outer Layer): Delivers material for the corrugated outer wall, can use different materials/colours
Precision Co‑Extrusion Die Head (dual‑channel spiral mandrel type): Ensures uniform wall thickness distribution and superior interlayer bonding
Corrugator Forming Unit (horizontal/vertical shuttle‑type): Precisely forms the corrugated outer wall with water‑cooled aluminium mould blocks
Vacuum Forming System: Ensures perfect adhesion between inner and outer layers
Multi‑Stage Spray Cooling Tanks: Rapidly cools and solidifies the completed double‑wall pipe
Heavy‑Duty Caterpillar Haul‑Off Unit: Provides stable, non‑slip traction without deforming the pipe
In‑Line Belling Unit: Forms integrated double‑layer sockets for jointing
Automatic Planetary Cutter: Precision cutting to preset lengths with smooth, burr‑free ends
Auto Tipping / Stacking Rack: Safely collects and stacks finished large‑diameter pipes
