Abstract
RSTRENG Effective Area method and two other methods,ASME B31G and RSTRENG 0.85dL,were used to compute and evaluate the remaining strength of one segment of a pipeline with corrosion defects.With the results analyzed and assessed,the maximum safe pressure,safety factor and burst pressure were given,which provide a reliable safe guarantee and excellent management and operation for the pipelines.
