Preparation of Synthetic Iron/Carbon Calibration Standards for Neutron ElasticScattering Analyses of Cast-Iron Pipes. Final Report, January 1996-February 1997

摘要

Binary mixtures of iron chips and graphite flakes were prepared as syntheticstandards for calibrating and evaluating the feasibility of using neutron elastic scattering by Penetron, Inc., for determining in-situ corrosion of cast-iron piping used for natural gas distribution. The in-situ measurement of corrosion severity was based on the Penetron concept that carbon/iron ratios would vary from the normal ratios present in uncorroded pipes. If changes in the carbon/iron ratios could be detected in-situ, they might then be used to detect pipes prone to possible leakage.
