Model Modules to Assist Assessing and Controlling Stress Corrosion Cracking (SCC)
Validation of the newly available direct assessment methodologies for both external corrosion and stress-corrosion cracking; development of improved modules for assisting operators with controlling the parameters that cause stress-corrosion cracking; approaches for improving the integrity of systems with wrinklebends and buckles; and a viable approach to running fracture that should help operators minimize its consequences when ruptures occur. Specific goals of the project are to: (1) develop and validate a mechanism for near neutral stress corrosion cracking (NNSCC) that reflects operational and right-of-way scenarios typical of US pipelines; (2) quantify field characteristics in terms of cracking colonies and pipeline operation for line pipe from X52 thru X65; (3) establish hydrostatic retest protocols to assist in controlling high pH SCC in terms of pipeline operation represented by compressor discharge pressure and temperature for line pipe from X52 thru X65; (4) package the high pH SCC model in user-friendly format, including graphical-user interface to provide output indicative of integrity implications related to hydrostatic retesting; and (5) quantify hydrogen evolution and establish relationships between hydrogen and evolution of microplastic strain, as basis to establish related kinetics for NNpHHSCC. This is a consolidated project with Project No 162, Project No 164, and Project No 165.
