This work aims to improve pipeline segment prioritization for stress corrosion cracking (SCC) excavations. Specifically, it is aimed at optimizing the technical accuracy and the cost of the Association for Materials Protection and Performance (AMPP,…
Stress corrosion cracking of line pipe from the soil side involves slow crack growth at stresses which may be as low as half the yield strength, this slow crack growth continuing until the crack penetrates the wall to produce a leak or until the…
Previous research showed that the threshold stress for stress corrosion cracking (SCC) of X52 steel under steady loading could be controlled at a high level (near the yield strength) if the steel were strained between 4 and 7 percent and then aged at…
Hydrostatic retesting is a practical technique for remov1ng colonies of stress-corrosion cracks from gas lines before service failures occur. However, at present operators have no sound basis for choosing a retest interval. Rather, they use arbitrary…
Environmental cracking processes are caused by the synergistic interaction of a corrosive environment and applied service stress (mechanical contribution) with a susceptible pipeline material. Stress corrosion cracking (SCC) is one form of…
This report summarizes the work completed in PRCI SCC-2-12A project: The Effect of Pressure Fluctuations on the Growth Rate of Near-Neutral pH SCC, which is Phase 3 of the work on the same subject of investigation. The following insights from the…
