Product
Corrugated Pipe
Double-wall HDPE pipe with corrugated outer wall and smooth inner wall; provides high ring stiffness and low friction in drainage systems, culverts and mine discharge lines.
Product Summary
High ring stiffness with double-wall structure
Corrugated pipe manufactured in SN4–SN8 and SN16 classes; thanks to its corrugated outer geometry, it achieves high ring stiffness against external load without increasing the amount of material. The smooth inner surface preserves hydraulic efficiency by keeping the Manning coefficient low.

Technical Approach
Technical features highlighting the Corrugated Pipe product
Exceeding a 50-year pipe service life depends not only on pipe quality, but also on correct trench geometry and sidefill compaction.
Low friction coefficient with smooth inner surface
Full resistance to corrosion and chemical effects
Leak-tight joint with gasket or electrofusion
Ring stiffness decisive for burial depth
SN class selection is directly related to the expected traffic load and burial depth.
Product Structure
A structure meeting engineering requirements in a single product
The pipe consists of two walls: a smooth carrier surface on the inner side with a low friction coefficient; and a corrugated profile on the outer side providing ring stiffness. The void formed between the two walls reduces the weight of the pipe while maintaining structural stability under external load.
