Abstract: Empirical formulas of residual strength of corroded pipeline were introduced according to four standards,ASME B31G-2009,BS 7910-2005,PCORRC and API 579-1/AMSE FFS-1-2007,and the effects of four evaluation criteria on predicted results were analyzed and compared.The residual life of some gathering pipeline was predicted by formula from AMSE B31G-2009 standard,finite element method and reliability analysis.The results show that the residual strength predicted by the method according to API 579-1/AMSE FFS-1-2007 was the most conservative,followed by that according to ASME B31G-2009 for different strength pipelines.Using the methods according to BS 79102005 and PCORRC got the similar curve,but the result of the former was slightly bigger than that of the latter.To improve the precision of prediction, nonlinear finite element method and reliability analysis were applied to predict the residual life further.The residual lives predicted according to the empirical formula,finite element method and reliability analysis were relatively close,which were 10.8 years,12 years and 13.6 years,respectively.
