Reliability Computation of Bursting Strength of Ammonia Pipelines Based on Chois Criterion

Chennakesava R Alavala

The aim of the present work was to predict the bursting pressure of ammonia pipelines using Choi’s criterion. The failure of the pipes was evaluated based on the Tresca, von Mises criteria and Weibull criteria. The significance of crack dimensions was recognized using Taguchi techniques. The highly influencing crack dimensions were pipe thickness, crack depth and grade of steel. The results obtained by the Choi’s criterion have been validated with in line with those of experimentation, ASME B31G, modified ASME B31G, DNV-RP-F101, SHELL-9, RSTRENG, PCORRC, LG-18 and Fitnet FSS.
