It is well-known that corrugated pipes can offer exceptional material savings, good hydraulic (flow) properties and high compression strength. For these reasons corrugated pipes have shown high growth rates in recent years resulting in the continued development of its production technology. Here we aim to give you an overview of the main characteristics, types and production technologies of corrugated pipes and show how well the corrugated pipe for sewage and drainage applications acquits itself compared to its two main competitors, the concrete pipe and the solid wall PE pipe.

In the early days corrugated pipes benefitted from the growth in demand for telecommunication cable ducting.

But in terms of material conversion tonnage, cable ducting has now been overtaken by drainage and sewage pipes for construction and infrastructure. Corrugated pipes can be made of a wide range of different materials such as polyamide (PA),thermoplastic elastomers (TPE), thermoplastic rubber (TPR), polytetrafluoroethylene (PTFE), but the primary raw material in the manufacture of corrugated pipes for water transportation is high-density polyethylene (HDPE), followed by polypropylene (PP) and polyvinyl chloride (PVC).
