5456 aluminum plate API Std 650 mechanically-anchored tanks

There is no dome roof in the top of the vertical external floating roof oil storage tank, only the disc floating roof which can float up and down. The wall plates are connected by butt welding, and the construction is usually carried out by the forward installation method, and the storage capacity is usually more than 10000 cubic meters. Vertical internal floating roof API Std 650 mechanically-anchored tanks has both dome roof and internal floating roof. The internal floating roof floats on the liquid surface inside the dome roof oil tank and can float up and down. The storage capacity is usually between 1000 and 10000 cubic meters.Impact Test Requirements for Oil Storage Tanks Primary Components
All API Std 650 mechanically-anchored 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 API Std 650 standard published by the American Petroleum Institute (API) is designed to provide the petroleum industry with welded steel tanks for use in the API Std 650 mechanically-anchored tanks storage of petroleum products and other liquid products commonly handled and stored by the various branches of the petroleum industry.Insist on the spirit of development and indomitable entrepreneurship; the spirit of leading science and technology and striving for first-class affairs; the spirit of strict management and market development; the spirit of taking the lead in setting an example and selfless dedication; and the spirit of people-oriented and enterprise ownership.We have replenish steel materials stocks, now there are huge stocks of S355JR, A36, API Std 650 mechanically-anchored tanks A572 Gr 50, 16Mo3, A516 Gr 70, ABS grade A, AH32, AH36, EH36, SPA-H, SG295,SM700C etc steel materials.
