Generally, external environment corrosion should be considered before design and construction of API Std 650 ambient temperature tanks and so on storage tanks. The corrosion on the outer surface of storage tank is often worse than that on the inner surface. Especially in the chemical industry area, there are often acid fog, alkali or salt dust in the atmosphere. These impurities form an active corrosive medium with dew or steam and oxygen in the atmosphere. The corrosion of the external environment of the storage tank shortens the maintenance period of the storage tank, even causes the storage tank to be scrapped in advance, which affects the normal operation of the storage and transportation.
Impact Test Requirements for Oil Storage Tanks Primary ComponentsAll API Std 650 ambient temperature 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.
