PC program speeds new criterion for evaluating corroded pipe

Abstract

An improved method for evaluating the remaining strength of corroded pipe reduces the original B31G method's inherent over conservatism. The modified criterion was developed on Project PR 3-805. One of the most important results of the PR 3-805 project was the development of a personal-computer program, RSTRENG. The program facilitates the analysis of corroded areas via the effective-area method. This article discusses the modified criterion and shows its application in a sample calculation using RSTRENG.
