Measuring Steel Cracking Susceptibility in Sour Pipeline Environments
Steels are evaluated in Strategy-A 4.0 for susceptibility to sulfide stress cracking (SSC), hydrogen induced cracking (HIC) and stress oriented hydrogen induced cracking (SOHIC) mechanisms in sour pipeline environments. The system provides access to a comprehensive knowledge base containing information about carbon steels and requirements for HIC, SSC and SOHIC resistant behavior.
Strategy-A 4.0 utilizes data and rules from laboratory research stemming from a comprehensive Joint Industry Program (JIP), field experience, literature and domain expertise to improve steels evaluation and pipeline inspection. Analysis includes determination of environmental severity to cause cracking, compatibility of steels used in construction, fabrication techniques and risk assessment in terms of crack growth potential and prioritization of inspection. Its embedded JIP data-based rules and extensive domain expertise assist in accurate quantification of cracking susceptibility.
