Abstract

While mechanical damage to pipelines is a common occurrence, the impact of mechanical damage on pipeline remaining life is not easily determined.  The mechanical damage features, such as residual stresses and stress concetrations, will determine the effect of the damage on pipeline remaining life.  Empirical relationships between damage features and burst pressure have been developed and adopted into national and international standards, but they are conservative to encompass the scatter in the data.
