Double Layer Corrugated Pipe Extrusion Line

The double-wall corrugated pipe production line manufactures pipes with a corrugated outer wall for high rigidity and a smooth inner wall for optimal flow. It integrates co-extrusion, vacuum forming, and cooling to produce lightweight, durable pipes ideal for high-load drainage, sewer systems, and cable protection. The line ensures efficient, continuous production of pipes meeting international standards like ISO 21138.

1. High-Strength Structure with Optimized Material Use

  This line utilizes co-extrusion technology to simultaneously form a smooth inner layer and a corrugated outer layer, creating a pipe with exceptional ring stiffness (up to SN16) while using minimal material. The unique design provides superior load-bearing capacity, making it ideal for deep burial applications.

2. High-Speed Production with Precision Control

  Equipped with advanced modular corrugators and synchronized vacuum calibration systems, the line achieves stable production speeds of 15-25 meters/minute. The integrated PLC ensures precise control over wall thickness and wave dimensions, guaranteeing consistent quality across long production runs.

3. Energy Efficiency and Automated Operation

Featuring optimized heating zones and high-efficiency drive systems, the line reduces energy consumption by up to 25% compared to conventional models. Automated cutting, marking, and coiling systems minimize labor requirements and enhance overall operational efficiency.

1. Municipal Sewer & Wastewater Systems

This line produces high-strength pipes for main sewer lines, wastewater collection, and treatment plant networks. The smooth inner wall ensures excellent flow capacity, while the corrugated outer wall provides the structural strength needed for deep burial and heavy traffic loads.

2. Road & Infrastructure Drainage

The pipes are widely used for highway underdrain systems, airport runway drainage, and railway embankment drainage. Their high ring stiffness and lightweight design facilitate quick installation and long-term performance under high static and dynamic loads.

3. Industrial & Landfill Drainage Applications

Ideal for industrial site surface water drainage, landfill leachate collection systems, and mining dewatering projects. The pipes' chemical resistance and durability ensure reliable operation in demanding and corrosive environments.

4. Agricultural Irrigation & Field Drainage

Used for subsurface field drainage and main irrigation canals to improve soil conditions and water management. The pipes help prevent waterlogging and salinization, promoting sustainable agricultural productivity.
