API 650 ground supported tanks allowable stresses

After more than 20 years of ups and downs in the steel industry, BBN company's customers have covered South America, North America, Europe, Africa, Southeast Asia and the Middle East and other countries and regions. We treat every customer who inquires with us sincerely, whether you cooperate with us or not, we will provide you with the best quality steel solutions. Our company team also support the online customer service.The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently. However, if the inner and outer tanks API 650 ground supported tanks are supported by a common foundation, the seismic foundation loading shall be calculated using the lesser response modification values for either the inner tank or outer tank for both tanks and a dynamic analysis shall be performed to determine the combined effect.
Allowable Stresses: For Appendix R tanks, design allowable stresses shall be per API 620 large low pressure storage tank, Section R.3.3.Fabricated to API standard 650 Welded Tanks for Oil Storage Shop Assembled API 650 ground supported tanks Storage Tanks, these tanks are commonly used at oil and natural gas terminals, API 650 ground supported tanks processing plants, and midstream facilities located along pipelines at the pumping, compression, or metering stations. API 650 storage tanks are designed and fabricated considering operating pressures up to 2.5 PSIG, corrosion allowance, wind loading, and seismicity.[Enterprise Spirit]: professional, honest, dedicated and innovative.[Enterprise Tenet]: provide customers with satisfactory steel products and services.[Enterprise Policy]: customer satisfaction is our pursuit.
