9m diameter API Std 650 flexible liquid storage tanks

API 650 internal floating roof oil tank is a volatile liquid storage tank with a combination of a dome tank and an internal floating roof structure, which is a floating roof assembled under the dome of the API Std 650 flexible liquid storage tanks storage tank. The combination of the vault roof outside the API 650 storage tank and the floating roof inside the tank has been widely used in gasoline, aviation kerosene and more volatile chemical liquids.

Impact Tests for High Alloys
Impact tests are not required for the high-alloy (austenitic stainless steel) API Std 650 flexible liquid 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.

Treatment of API Std 650 flexible liquid storage tanks welding defects:
1. Lack of fusion: once found, it should be shoveled and grinded off before re welding.
2. Incomplete penetration: over standard defects shall be removed and re welded. When welding on both sides, the shallow side of the groove can be grinded and shoveled to expose the welding root on one side, and then the welding is repaired.
3. Slag inclusion: over standard defects shall be removed and re welded.
4. Crater: weld to full after grinding.
5. Air hole: if the internal air hole exceeds the standard, it shall be welded again after being removed by grinding shovel, and the surface air hole shall be removed by grinding wheel and then repaired.
