ASTM A216 grade WCA external floating roofs API standard 650 self-anchored flat-bottom steel tanks

The cleanliness of the API standard 650 self-anchored flat-bottom steel tanks has a great influence on the safety of the tank and the quality of the oil stored. Keeping the API standard 650 self-anchored flat-bottom steel tanks clean can slow down the corrosion of the tank wall and reduce the pollution to the oil. If the inside of the API standard 650 self-anchored flat-bottom steel tanks is not cleaned all the year round, a lot of rust and metal impurities will be produced in the tank. These impurities will cause the oil to slowly oxidize and deteriorate. The impurities mixed into the oil will also block the filter and oil circuit, causing oil supply failure.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.

API 620 Steel Oil Tank Bottom and Shell Support
The tank API standard 650 self-anchored flat-bottom steel 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 is used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API standard 650 self-anchored flat-bottom steel tanks API 650 tanks with diameters between 8'-300', which are suitable for refineries, terminals, pipeline facilities and other projects.
