Technical Inquiries for API Standard 650,Welded Tanks

Please furnish details on the maximum allowable tank diameter and height for tanks built in accordance with API 650.The appropriate combination of tank diameter and height is a design consideration.There are several factors which influence this. API 650 does not cover an explanation of these factors.Technical Inquiries for API Standard 620,Design wind or seismic,the maximum allowable compressive stress may be increased to 1.33 times S cs. For seismic loading only,the maximum allowable compressive stress shall be per Appendix L,Sections L.5.2 and L.5.3. For the test condition,API 620 does not provide specific guidance on the maximum allowable compressive stress. 5.5.6 10th Tank nozzle loads calcstressPassing a storage tank nozzle loads has been a nightmare for the most stress engineers.Low allowable tank nozzle loads as well as tank settlements make the task challenging.If a tank is designed based on API 650 the allowable nozzle loads in a discontinuity area can be calculated by the formula mentioned in appendix P of API 650.
