Modeling and Experimental Insights of Sulfide Stress Cracking Corrosion Mechanism

A model was built that describes stress field and hydrogen activity at the direct vicinity of a crack tip. A second model was based on the cohesive zone simulates the kinetic of a crack growth. Experiments using hydrogen permeation under stress on flat un-notched & notched specimens yielded data comparable to the simulations.

Quenched and tempered martensitic steels for Oil Country Tubular Goods can be subject to Sulfide Stress Cracking when exposed to a sour environment. Basically the failure mechanism of SSC includes an initiation step and a propagation step of a crack. Focusing on the latter it is primary to model the conditions for crack propagation for avoiding crack growth or for promoting crack arrest. With this view a hydrogen stress driven model has been built that describes stress field and hydrogen activity at the direct vicinity of a crack tip. Complementary a second model based on the cohesive zone simulates the kinetic of a crack growth. In parallel experimental works combining hydrogen permeation and static loads on notched tensile specimens brought experimental data that were compared to simulation outputs. The respective influence of diffusible and trapped hydrogen on the cracking mechanism received a specific focus based on fractographic analyses.

Key words: Sulfide Stress Cracking, modeling mechanism, OCTG martensitic pipes, kinetic of crack propagation, trapped and diffusible hydrogen
