In-ditch nondestructive material verification for yield strength and toughness has been a growing interest to the pipeline industry in the continuous efforts to further raise pipeline safety and efficiency. It can complement or substitute alternate techniques such as material extraction or hydrostatic pressure tests. This work is the first use of the Hardness, Strength, and Ductility (HSD) Tester by PRCI to measure the equivalent of the API 5L yield strength from only testing the out-side diameter surface of pipe joints without significant material removal. The procedure explicitly account for...

The procedure explicitly account for through thickness variations.
