The scope of API 653 includes tanks built to API 650 and API 12C.This leads to an overlap in the scope of the tanks covered by the standards.Therefore,more information is needed about a tank in order to decide the best inspection standard to use.For example,if it is a double-wall horizontal UL 142 tank,then STI SP001 probably is a better Re API 620 verses 650 standard? - NDT.netAug 30,2019 API 650 tanks Flaw Acceptance Criteria#0183;02:03 Dec-23-2010 Re API 620 verses 650 standard? In Reply to Robert P.at 00:08 Dec-22-2010 (Opening)..API 620 covers a higher pressure and temperature rating than tanks than API 650 (atmospheric storage tanks),you need to decide what your design parameters are and then apply the relavent code to cover materials,welding,NDT etc.
