API standard 650 flexible liquid storage tanks allowable longitudinal membrane compression stress in shell

API standard 650 flexible liquid storage tanks belongs to metal oil tank. Metal oil tank is a kind of vessel made by welding steel plate. The common shapes of metal tank are vertical metal tank, horizontal metal tank and spherical metal tank. The advantages of API standard 650 flexible liquid storage tanks etc. metal oil tank are good sealing, not easy to leak, can be installed with heating and insulation function, metal tank can withstand high internal pressure, large vertical metal tank such as API standard 650 flexible liquid storage tanks also has the characteristics of small floor space and large storage capacity.

API 620 Steel Oil Tank Bottom and Shell Support
The tank API standard 650 flexible liquid storage tanks under-bottom insulation shall be designed to resist the combined pressures from the product load, the overturning seismic load and the vertical seismic load. These seismic pressures may be combined by SRSS.
The bearing ring under the shell shall be designed to resist the calculated OLE peak compressive force in the tank shell due to overturning (see API 650 oil tank, Section E.6.2.2), including dead and live loads. A 33 % increase in allowable bearing stress is permitted.

API 650 tanks in which liquid fluids are stored and designed to withstand atmospheric pressure operation, less than 18 kPa, or internal pressures not exceeding the weight of the API standard 650 flexible liquid storage tanks roof, with temperatures no higher than 93, 3 C are included in the scope of this design code.
