A Corrugated Pipe is a tube or pipe with parallel ridges on the surface. The Corrugated Pipe has ridges and grooves on the upper surface and is made primarily of steel and high density polyethylene. Corrugated pipes are often found in drains and may be lined or coated. They are highly flexible and durable, with a high degree of corrugation. In the case of these pipes, abrasion is at the lowest degree at the inner wall. In addition, Corrugated Pipe is used in areas where stability, strength, as well as longevity are essential, such as drains.
