Factors affecting the crack-initiation of pipeline infrastructure in the oil and gas
An essential step in materials degradation is the determination of the failure mechanism. To understand better the
mechanism of the crack initiation process, key metallurgical and environmental elements that can affect the cracking
phenomena were investigated and are reviewed. The complexity of both cracking phenomena results from the dependence
of SCC and HIC on multiple metallurgical, mechanical, and environmental parameters that may all influence both crack
initiation and propagation; e.g., composition, microstructure and non-metallic inclusions in the steel, applied stress, water
chemistry in the field, and ionic concentrations in the groundwater near the pipe surface to name a few for SCC. In
addition, for HIC phenomena, one can add the concentration of H2S in the fluids trans-ported in the pipe as well as
concentration of CO2, pH, etc.
Cracking of line pipe steels is analyzed critically, with attention to the crack initiation process.
