Erection requirements for API standard 650 welded tanks for oil storage

Unqualified welding quality of API standard 650 welded tanks for oil storage is prone to hidden dangers such as oil tank steel plate cracks and leakage. To avoid this situation as much as possible, it needs to be avoided when the oil storage tank is manufactured. Scientific and reasonable measures are adopted to control the welding quality when welding the API standard 650 welded tanks for oil storage. How to reasonably control the welding process quality of oil storage tanks?

API 620 Steel Oil Tank Bottom and Shell Support
The tank API standard 650 welded tanks for oil storage 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.

The Standard has gained international recognition and is the standard of choice of most builders of large liquid above ground API standard 650 welded tanks for oil storage storage tanks. One reason for this is that the API 650 Standard was created and is revised by API committees comprised of the world s best tank structural engineers who also rely on the experience of tank owners and tank construction companies.
