It is then vital to assess new and existing pipeline designs for running ductile fracture (RDF). RDF is a phenomenon in which a defect develops into a crack propagating along the pipeline, sustained by the pressure forces from the escaping fluid.
Hans Langva Skarsvåg, Research Scientist at SINTEF Energy Research, will present results of their recently published paper proposing an improved material curve and an improved method for calculating the crack-tip pressure, which can lead to a more viable engineering tool for the prediction of RDF in CO2 pipelines.
