The Civil Engineering market, the HDPE double walled corrugated pipe is characterized by two types of production:
- Coil production with pulling wire 25 to 50m
- Bar production, 6 m long without pulling wire
Smooth inner wall and corrugated outer wall
The product range begins at Dia40 and ends at Dia250mm
Extrusion lines are distinguished by two criteria, the speed of production and the mode of production, that is Bars or Coils.
- The production rate depends on the cooling capacity of the corrugator, the longer the corrugator is, the better its cooling capacity will be. Thus each corrugator is available in 3 or 4 lengths. CL-LL-SL (Short – Long – Long Long – Super Long)
- bar production 6m without pulling wire
Production in Coils requires a winder, automatic or semi-automatic depending on production speeds. The inner skin is adapted to allow an adequate bending radius.
Bar production requires a saw and a reception bench instead of the winder. The inner skin will be adapted to provide the desired rigidity.
