This report summarizes the outcomes of the second year of PRCI ECA-1-1. Concretely, specific methodologies developed to improve the NDE-FEA framework have been discussed (as elaborated in T2.3: "Evaluation and improvement of 3D NDE - FEA…
Describes a new non-destructive electromagnetic sensor for assessment of bulk strength and toughness of new and vintage steel pipelines operating in any environment.
The focus in this project was a workshop with the objective of promoting the standardization of fracture toughness testing procedures applicable to pipeline girths welds using SENT specimens. The participants included those currently active in the…
Because one mechanical property of line pipe stipulated in pipe specifications is yield strength, and because the operating pressures of natural gas pipelines are determined on the basis of transverse yield strength, it is necessary to measure the…
The objective of this program is to identify reliable, field applicable nondestructive test methods that can be used for estimating the yield strength, tensile strength, and fracture toughness of line pipe steels. This will include the proper…
This study validates the use of either a mechanical or a hydraulic type of mill expander for measuring the yield strength of each joint of cold-expanded pipe. Yield pressure measurements were taken from both types of expanders in several pipe mills…
The focus in the present study was to establish whether there is a reasonable correlation between the Charpy Vee Notch (CVN) toughness and the non-destructive Potential Difference (PD) measurements of ferritic-pearlitic steels having a range of CVN…
This project is a JIP project with the overall objective of demonstrating that hardness data from randomly selected pipe samples could be used to determine the lower bound YS of an entire pipeline segment at a quantified confidence level, and that…
This study examines the relationship between ductile tearing accompanying ductile crack extension and the arrest behavior of line pipe steel. Ten pipeline steels were selected to represent the spectrum of current manufacturing technology for X-70…
