API Std 650 self-anchored flat-bottom steel tanks thickness

When encountering heavy rain or continuous heavy rainfall, the safe operation of API Std 650 self-anchored flat-bottom steel tanks will be affected. For example: the API Std 650 self-anchored flat-bottom steel tanks is submerged, the oil unloading valve and the flame arrester valve are broken by water and the oil tank leaks. The oil tank area must do emergency work to prevent rainstorm to ensure the safety of the oil tank. Here are some safety protection measures for API Std 650 self-anchored flat-bottom steel tanks in heavy rain.Impact Test Requirements for Oil storage tanks Primary Components
All API Std 650 self-anchored flat-bottom steel 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 internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API Std 650 self-anchored flat-bottom steel tanks External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.[Enterprise Spirit]: professional, honest, dedicated and innovative.[Enterprise Tenet]: provide customers with satisfactory steel products and services.[Enterprise Policy]: customer satisfaction is our pursuit.
