A524 grade I pipe API 650 unanchored flat-bottom tank

API 650 storage tanks API 650 unanchored flat-bottom tank are only suitable for containers that can evenly support the entire bottom and containers for non-refrigerated equipment with a design maximum temperature of 200 degrees Fahrenheit. It API 650 unanchored flat-bottom tank requires a minimum thickness of 3/16 inch. Other characteristics of the API 650 storage tank are: it is composed of carbon steel, austenitic duplex stainless steel and aluminum.

Compared with the external floating roof API 650 unanchored flat-bottom tank, the internal floating roof API 650 unanchored flat-bottom tank has the advantages of protecting the floating roof from wind and rain and ensuring the quality of liquid storage under the floating roof. At the same time, because the inner floating plate is in the tank, there is no rain and snow load, so the central drainage pipe and escalator and other accessories on the floating plate can be omitted. In addition, under the same sealing conditions, the internal floating roof tank can further reduce the evaporation loss compared with the External floating roof tank.

Impact Test Requirements for Oil Storage Tanks Primary Components
All API 650 unanchored flat-bottom tank 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.
