API standard 650 closed top welded storage tanks roof deck reinforcing plates

API 620 Steel Oil Tank Bottom and Shell Support
The tank API standard 650 closed top welded 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.Welded steel API standard 650 closed top welded storage tanks storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API standard 650 closed top welded storage tanks all adopt on-site production and installation of storage tanks.The Peru customer has cooperated with us since April 2015, and then they purchased 300 tons A36 mild steel plates as trial order. Since then, they book more than 1000 tons from us every time, and about two times every year. They asked SGS test every time. Through our cooperation those years, we have built very good relationship and they entrust us to buy other related API standard 650 closed top welded storage tanks products for them from China also. And they have introduced us good customers in Peru, among which there are also governmental projects. It is a win-win cooperation between us.The foundation design of the API standard 650 closed top welded storage tanks should meet the requirements of foundation stability and deformation, that is, the API standard 650 closed top welded storage tanks foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the API standard 650 closed top welded storage tanks and cause distortion and deformation of the tank wall and bottom plate.The company's after-sales service team is a high-quality professional team.
