A573 Gr 70 plates API 650 carbon steel storage tanks

After using for a certain period of time, it is necessary to check the corrosion protection of the metal oil tank and paint the outer wall of the API 650 carbon steel storage tanks with anti-corrosion paint. The inlet and outlet valves of API 650 carbon steel storage tanks shall be inspected and maintained regularly to ensure they are in good condition. Oil tank will produce a lot of dirt when it is stored for a long time. Usually, the cleaning cycle of metal oil tank is about three to five years.

Impact Tests for High Alloys
Impact tests are not required for the high-alloy (austenitic stainless steel) API 650 carbon steel storage tanks base materials, nickel alloy based materials, aluminum base materials, and weld deposited for the nonferrous (aluminum) materials. Impact tests are not required for austenitic stainless steel welds deposited by all the welding processes for services of –200°F and above. Austenitic stainless steel welds deposited for service below –200°F by all welding processes shall be impact tested in accordance with Q.6.2 except that the required impact values shall be 75% of the values as given in Q.2.2.2, Item c.

API 650 petroleum storage tank pipeline stress and product pressure, tank pressure, uniform or non-uniform temperature difference between the tank wall and the tank bottom, which cause the radial displacement and longitudinal rotation of the API 650 carbon steel storage tanks tank wall at the opening to affect the oil tank wall The impact is obvious. Therefore, the design must ensure that the load applied by the external pipeline on the opening of the tank wall is within the safety limit. If the stress of the API 650 carbon steel storage tanks connecting piping is not handled properly, the wall of the API 650 petroleum storage tank may deform or even rupture, causing a major accident.
