API standard 650 aboveground petroleum storage tanks sheet and plate

One of the most widely used design codes is the API 650 Standard, from the American Petroleum Institute. The main objective of this standards API standard 650 aboveground petroleum storage tanks is, through the requirements contained in its various sections, to facilitate the purchase and construction of vertical, aboveground, welded fabricated tanks assuring that required safety regulations are met.

Impact Test Requirements for Oil Storage Tanks Primary Components
All API standard 650 aboveground petroleum 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.

Tank cracks are common API standard 650 aboveground petroleum storage tanks defects, mainly including tank wall cracks, internal cracks, weld zone cracks. The reason for these defects may be that the defects not exceeding the standard existed in the early stage of API standard 650 aboveground petroleum storage tanks construction, which become obvious after the later use. Or in the process of using the API standard 650 aboveground petroleum storage tanks, the tank body material generated new defects due to corrosion, pressure, wear and other reasons, and tank cracks.
