Corrugated riser pipes are commonly employed to facilitate the upward flow in shafts, tanks, and similar structures. These pipes, which possess a ribbed or grooved surface, provide enhanced structural integrity and durability. It is important to note that these pipes are typically supplied without sleeves.

The utilisation of corrugated riser pipes offers several advantages in various industries. The ridges or grooves on the outer surface of the pipes significantly increase their resistance to external forces and provide additional strength. This feature makes them suitable for applications involving challenging conditions, such as underground installations.
