EVALUATING PIPE--CONCLUSION. PC PROGRAM SPEEDS NEW CRITERION FOR EVALUATING CORRODED PIPE

An improved method for evaluating the remaining strength of corroded pipe has been developed. The method is based on the original B31G method but reduces the method's inherent overconservatism. The modified criterion was developed on Project PR 3-805 sponsored by the American Gas Association's Corrosion Supervisory Committee. 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. The first of two articles (O&GJ, Vol. 88, No. 32, pp 56-59) outlined how the original criterion was developed and its shortcomings. This conclusion discusses the modified criterion and shows its application in a sample calculation using RSTRENG.
