API 610 has a table of allowable loads for pump nozzles. Also there are 3 equations listed in Appendix F for pump allowables. Some companies have a practice of only satisfying the allowable loads specified in the table. All 3 equations need not be checked . Is this approach OK ? There are pumps made to ISO standard which has very conservative pump allowable equations to be satisfied. Similarly is it necessary to satisfy all 3 equations of appendix F of API 610 ?
