Production line introduction

How the Hollow Wall Winding Pipe Production Line is engineered, and which sub-assemblies protect the properties your customers actually buy.

A spiral winding line producing large diameter hollow wall pipe for drainage, culverts and storage tanks.

Every BENK line is matched to the material and product you actually sell. The extruder, die, calibration or forming section and the downstream automation are sized together, then assembled and trial run in our Zhangjiagang works before shipment, so the performance you see in the factory acceptance test is the performance you install. The machine frame is finished in RAL 5021 water blue with a semi-matt powder coating.

Technical Parameters of Hollow Wall Winding Pipe Production Line

Reference values for the standard configuration. Final width, thickness, speed and output are confirmed against your material, product drawing and target capacity.

Specifications are shown for the standard range; customized widths, thicknesses and outputs are engineered on request.

Production line technical advantages

Every sub-assembly below is selected to protect the properties your customers buy: transparency, gauge, strength and surface.

01

Mould block forming

Continuous mould block chains with water cooling form the corrugation and hold pitch and depth stable at production speed.

02

Inner and outer layer control

For double wall pipe, separate extruders feed the inner and outer layer so wall thickness ratio can be optimized.

03

Vacuum and cooling

Vacuum assisted forming plus staged cooling prevent deformation when the pipe leaves the mould blocks.

04

Servo haul-off

Servo driven haul-off matched to the corrugation keeps the pipe round and the cut square.

05

Compact footprint

The mould block loop is arranged for a short floor footprint, which matters when the line is installed in an existing hall.

06

RAL 5021 finish

The machine frame is powder coated in RAL 5021 water blue with a semi-matt finish.

Production line advantages

  • Mould block forming — Continuous mould block chains with water cooling form the corrugation and hold pitch and depth stable at production speed.
  • Inner and outer layer control — For double wall pipe, separate extruders feed the inner and outer layer so wall thickness ratio can be optimized.
  • Vacuum and cooling — Vacuum assisted forming plus staged cooling prevent deformation when the pipe leaves the mould blocks.
  • Servo haul-off — Servo driven haul-off matched to the corrugation keeps the pipe round and the cut square.

Built to run

Material preparation, feeding, downstream handling and packing can be integrated into one turnkey scope.

Why buy from BENK Machinery

Extrusion specialists, not traders

BENK designs and builds extrusion lines in Zhangjiagang with an in-house R&D and process team, so machine selection is matched to your resin and product instead of a catalogue number.

Evidence before shipment

Every line is assembled and run in our works. You receive trial video, gauge and output records, and are welcome to attend the factory acceptance test.

Total cost, not lowest price

Energy-efficient drives, permanent magnet motors and optimized heating reduce kWh per tonne, which usually matters more over five years than the initial purchase price.

Real commissioning support

Our engineers install, commission, train your operators and stay involved until the line hits the specified output and quality on your material.

Spares and response

Critical spares are stocked for fast dispatch, and the Siemens Ethernet control platform allows remote diagnosis before a service visit is needed.

Upgrades as you grow

Co-extrusion, gauge control, automation and downstream equipment can be added later, protecting your original investment.

Frequently asked questions

The questions buyers ask most often about this corrugated.

What is the difference between single wall and double wall corrugated pipe?
Single wall pipe is lighter and more flexible for conduit and light drainage, while double wall pipe has a smooth bore and a structural outer wall for gravity drainage and sewer duty.
How is the corrugation formed?
A continuous mould block chain forms the corrugation under vacuum, and the mould blocks are water cooled so the shape is fixed before the pipe is hauled off.
What sizes can be produced?
The size range is listed in the specification table, and additional mould block sets let the same line cover the whole range you sell.
Can you supply the mould blocks?
Yes. BENK supplies the complete mould block sets for each pipe size together with the forming and calibration tooling.
