Mathematical model for life prediction of damaged PE 80 gas pipes

This paper deals with new approach to the problem of predicting lifetime of damaged thick-walled gas pipes made of high-density polyethylene (PE-HD 80). Gas pipeline system condition affects on reliability and safety of the gas use. At the same time the quality of pipelines imposes itself as the economy and the safety imperative. Investigations based on long-term experiments involving three parameters: pressure, length and depth of initial axially notch type crack gave empirical mathematical model for life prediction of PE 80 gas pipes presented in the paper.
