Abstract
The problem of deteriorating water pipes, resulting in leaks and breaks, affects municipalities worldwide. Corrosion appears to be a leading factor affecting pipe strength and service life. While techniques to evaluate the corrosion damage of in-service pipes are being developed successfully, “affordable” methods to estimate the remaining strength of such pipes are presently not available. A three-dimensional finite element strength evaluation method, as presented herein, is able to predict the strength of corrosion-deteriorated cast iron water pipes subjected to specific loading conditions. It can be used by engineers to identify those pipe sections which require attention.
