API standard 650 liquid-storage tanks subsurface investigation and construction

Generally, the building area temperature of the API standard 650 liquid-storage tanks should be considered before the tank design and construction. The temperature in the API standard 650 liquid-storage tanks building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the API standard 650 liquid-storage tanks, the higher the corresponding pressure and the more volatile loss.

Impact Test Requirements for Oil Storage Tanks Primary Components
All API standard 650 liquid-storage tanks primary components of 9% or 5% nickel steel shall be impact tested in accordance with Q.2.2.2 through Q.2.2.4. Impact testing is not required for primary components of austenitic stainless steel, nickel alloy, and aluminum materials. Welds in high-alloy (austenitic) stainless steel shall be impact tested if required by Q.6.3.
Impact testing of plates, including structural members made of plate, shall comply with the following:a)Impact test specimens shall be taken transverse to the direction of final plate rolling. b)Charpy V-notch specimens shall be cooled to a temperature of –320°F for A353, A553, and A645 steels for impact testing.

The temperature requirements of the API 650 oil storage tank area are closely related to the evaporation loss, energy loss, API standard 650 liquid-storage tanks storage and storage platform tank materials and the selection of detection instruments, or the temperature of the API 650 oil storage tank area. The cost of storage has a direct impact.
