In-Situ Measurement of Tensile and Fracture Toughness Properties and Determination of Pipe Grade Using the Innovative ABI® Test
Haggag, F.M., "In-Situ Measurement of Tensile and Fracture Toughness Properties and Determination of Pipe Grade Using the Innovative ABI® Test," Gas Technology Institute Project 20568, Final Report, November 2008.
This Gas Technology Institute (GTI)-funded validation study on natural gas pipeline materials represents the gas industry's own independent confirmation of ABI® results for pipe grade determination, yield strength, and fracture toughness on representative gas pipeline steels.
GTI (now GTI Energy) is the natural gas industry's primary research organization, funded by gas utilities and pipeline operators. A GTI-funded study carries significant weight with gas industry decision-makers because it represents the industry validating a technology for its own use, rather than relying on the technology developer's claims.
The study tested ABI® on pipeline steels representative of those in the U.S. natural gas transmission system, providing the gas industry with confidence that ABI® results are reliable for integrity management applications. This independent gas industry validation complemented the DOE nuclear validation and DOT-funded research to establish ABI®'s credibility across the full range of its primary application sectors.
