A333 grade 6 pipe API standard 650 floating-roof tanks

Under the condition of static storage without receiving and sending operation, the temperature of gas space, evaporation rate, depth and pressure of vapor in the API standard 650 floating-roof tanks will change with the change of temperature and pressure in a day. The oil loss caused by the process of discharging oil vapor and inhaling air gas is called "small breathing" loss, which is also called static storage loss of oil tanks.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 standard 650 floating-roof 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.This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API standard 650 floating-roof tanks storage of petroleum, petroleum products. and other liquid products.Enterprise mission: to create value added steel products API standard 650 floating-roof tanks and provide first-class serviceWe are committed to quality.
