| In the present paper issues of pipeline design are discussed based on the findings of a recent research work. Specifically, mechanical aspects of ultimate limit state modeling are analyzed with respect to high grade pipeline steels and high usage factors. Criteria for limit state stress calculation and burst pressure representation are treated and their applicability and accuracy checked by experimental evidence. Besides, various definitions characterizing the state of yielding of pipes are investigated. Conclusions are drawn by comparing predicted yield pressures and test results. | |
