Our tools can locate almost any defect
Although a crack may be almost invisible to the eye, it can still weaken a pipeline enough to cause catastrophic failure. The types of cracks most likely to develop in operating pipelines are stress corrosion cracks (SCC), fatigue cracks, hydrogen-induced cracks and sulfide corrosion cracks. They can occur in the base material of the pipe, in welds and in the heat-affected zone adjacent to welds. Cracks can also appear in substandard axial and girth welds, and can occur in conjunction with other flaws such as dents, gouges and corrosion.
We have focused on finding solutions to the operator’s challengeto locate, identify, characterize and monitor the many types of cracks that may compromise pipeline integrity. Our technologies can inspect older pipelines, which have a propensity for weld-related cracks (seam, hooks). For accurate location and highlighting of cracks most likely to fail, our inspection capabilities can identify stress corrosion cracking (SCC) and cracks of unknown gestation. We also can employ recognized engineering techniques to predict rupture pressure when adjacent crack(s) interact, if extensive SCC crack fields are populated with both critical and subcritical cracks.
