Title: Development of Pipeline/Casing Model and Its Comparison with Experimental DataA large-scale computational finite element (FEA) model was developed that contained many features that could be used to help evaluate the condition of a pipeline inside casings without the difficulty and expense of measuring cathodic polarization within the casing. The casings provides protection of the pipeline as it crosses underneath roads or railroad lines. A series of 54 fractional factorial experiments were performed for the Pipeline Research Council International (PRCI) by the Midwest Research Institute. Their report was published in July of 1979. In these experiments eight factors were varied; four of them were 2-level factors and four were 3-level factors. There were 18 repeats of 36 unique experiments that were conducted. A computational model to simulate the experimental conditions in the PRCI report was developed using a finite element analysis computer code. This model was a simpler version of a more sophisticated large-scale model but it included all of the features of the experimental apparatus of the PRCI report. Comparisons were made between the model and the experimental measurements. Overall the agreement was found to be good. The model details and its comparison with the experimental data will be presented in the paper.
