Sažetak
This papers deals with new approach to life estimation of damaged thick-walled gas pipes made of high-density polyethylene (PE 80). The most common approaches to polyethylene gas pipes durability prediction rely on methods of fracture mechanics, which involve defining the stress intensity factor experimentally. However, such tests are carried out on standardized specimens neglecting the influence of real pipe geometry and processing method. On the other hand, these data are not always available to gas distributors, which are responsible for installed pipelines durability. Investigations based on long-term experiments involving three parameters: presure, length and depth of initial notch type crack gave empirical mathematical model for life prediction of polyethylene gas pipes.
