Ductile fracture propagation control in modern high strength steel pipeline for transportation of high pressure natural gas with H2 and CO2 contents: arrest requirements evaluation by numerical tool and full-scale testing verification
One of the most severe accidents which could occur in a gas transmission pipeline involves the linepipe wall failure and subsequent fracture initiation, which may evolve in a long running fracture propagation if the material toughness properties are not adequate. The most acknowledged approach for ductile fracture propagation assessment is the...

Application of Distributed Fiber Optic Sensing for Pipeline Integrity and Security
Even the smallest leak can have devastating consequences. The protection and monitoring of pipeline infrastructure is critical to the continued performance of the pipeline. Loss of integrity, through accidents or malicious activity, can have a significant impact on the environment, on reputations and on finances. Distributed Fiber Optic Sensing is...

Large Stand-Off Magnetometry (LSM) for Buried Pipeline Inspection - Experimental study: Influence of dent depth on residual magnetic signal

Large Stand-Off Magnetometry (LSM) for Buried Pipeline Inspection - Experimental study: Influence of dent depth on residual magnetic signal
Large Stand-Off Magnetometry (LSM) for Buried Pipeline Inspection - Experimental study: Influence of dent depth on residual magnetic signal
Dents are among the anomalies which may be a threat to safe operation of pipelines. Dents are characterized by plastic deformation, which causes changes in the magnetic properties of the ferromagnetic pipe wall. Skipper NDT, a company at the forefront of LSM technology, conducted trials to characterize changes in magnetic properties around dents...
