Using level 2 assessment procedures of locally metal loss in API 579, the calculation methods of remaining strength factor (RSF) are studied for cylindrical shells with ellipsoidal and spherical pits, convenient calculation formulas are established. The RSF of cylindrical shells with axial ellipsoidal and spherical pits are calculated systematically, and the values of the RSF which can be directly used for en-gineering assessment are presented in charts in terms of the two parameters α and g. The assessment methods of pits on cylindrical vessels in GB/T 19624 are discussed.
