| Abstract: | Based on the specifications in GB 50341-2003 and API 650-2009 for the tanks subjected to minor internal pressure,the related formulas used in calculation were deducted,including that for calculations of minimum required area of compression ring,maximum allowable internal pressure of keeping the bottom of tank on ground and the roof rupture pressure.Through the calculation of the limit area of compression ring in accordance with the design method for frangible roof structure,the theoretical base in above mentioned standards for the tanks subjected to minor internal pressure was explained,and the differences of the related formulas in Chinese and abroad standards and the causes were analyzed.Additionally,the problems needed to be noted in using these formulas in design were presented. |
