200-4000mm HDPE Hollow Wall Winding Pipe Production Line for Sewage Road Drainage

The Large-Diameter HDPE Hollow Wall Spiral Structural Wall Pipe Production Line manufactured by Qingdao Huashida Machinery Co., Ltd. is professional HDPE hollow wall winding pipe extrusion equipment integrating imported German advanced plastic extrusion technology and independent intellectual property rights. This full automatic structured wall pipe production line reaches international advanced manufacturing standards for municipal drainage plastic pipe machinery.

The large-diameter HDPE hollow wall spiral pipe produced by this HDPE structured wall pipe machine is an ideal replacement for traditional cement pipe, cast iron pipe and ceramic drainage pipe. With decades of mature plastic pipe extrusion manufacturing experience and exclusive technical advantages, Huashida supplies stable, easy-to-operate high-output hollow wall winding pipe production line for global pipe manufacturers and municipal pipeline project investors.

This full set of HDPE hollow wall winding pipe production line is split into two core functional modules: square profile extrusion unit and spiral winding forming unit, with full supporting auxiliary equipment and intelligent control system.

Responsible for extruding customized PE/PP square hollow strips as raw materials for spiral winding pipes:

Single Screw Extruder → Profile Die Head & Mandrill → Vacuum Calibrator → Vacuum Cooling Tank → Spray Cooling Tank → Haul-off Unit

Realizes hot-melt bonding and large-diameter pipe forming of PE square strips:

Hot melt adhesive Extruder → Composite Spiral Die Head → Rotational Spiral Forming Unit → Automatic Cutter → Finished Pipe Bracket

The pipe produced by this large diameter structured wall pipe machine works under working temperature ≤45°C, widely applied in multiple municipal & industrial pipeline projects:

Core host of the HDPE hollow wall winding pipe extrusion line, equipped with water-cooling forced feeding structure and grooved feeding barrel to cut main motor power consumption. Long L/D ratio screw with mixing head achieves perfect PE raw material plasticization and stable high hourly output for mass pipe production.

Adopts integrated composite extrusion die head and rotary spiral winding forming technology, compact overall layout, stable hot-melt bonding effect to avoid pipe delamination, ensures uniform ring stiffness of finished large diameter HDPE hollow wall pipes.

Founded in 2003, Qingdao Huashida Machinery Co., LTD is a professional global developer, manufacturer and turnkey solution provider of full-series plastic extrusion equipment including HDPE hollow wall winding pipe production line. Over 70% of our machinery products are exported to Europe, America, the Middle East, Southeast Asia, Central Asia and Africa, serving more than 400 overseas pipe manufacturers and engineering contractors. Factory visits and customized equipment negotiation are warmly welcomed.

Besides plastic pipe manufacturing machines, we also produce matching pipeline anti-corrosion accessories: PE heat shrinkable sleeves, electro fusion sleeves and portable plastic extrusion welders, widely used for joint sealing of plastic drainage pipes, PU foam insulated pipes and 2PE/3PE oil & gas steel pipelines.
