A research project on the durability of Aluminized Steel Type 2 pipe installed in the metro Atlanta area has resulted in an outstanding report of the product’s performance. The study focused on the performance of pipes in storm sewer applications, so the majority of the pipes are connecting two catch basin structures. All of investigated pipes that were installed per industry guidelines are far exceeding the stated goal of a 75 year minimum service life for the product. The investigation is ongoing and this document will be updated as more data is added.
The study includes 105 pipes located in Gwinnett, Cobb, Forsyth, Hall, Barrow, Athens-Clarke, and Walton counties. The oldest pipe in the study group is 38 years old and the average age of the pipes is 20 years. All of the pipes were tested and documented per the NCSPA’s “Non-Destructive Testing Protocol for Corrugated Metal Pipe.”
