CSA G40.21 grade 260W plates API Std 650 aluminum storage tanks
API 650 petroleum storage tank basic knowledge, storage tank concept and use: API Std 650 aluminum storage tanks storage equipment for storing crude oil, gasoline, kerosene, petroleum and various non-volatile chemicals, API 650 petroleum storage tank is a storage and transportation system facility, oil refining, chemical industry An important part of the device.
Treatment of API Std 650 aluminum 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.
The tank 20-in. inside-diameter nozzle shown in Figure F-6 is located in solid plate in the sidewall of a cylindrical storage tank 148 ft in diameter in an area where the thickness of the wall plate, tw, is 11/2 in. A corrosion allowance of 0.10 in. is required on all surfaces of the tank exposed to the stored liquid. The total internal pressure, Pl + Pg, at the center of the opening is 24.9 lbf/in.2 gauge. The thickness of the API Std 650 aluminum storage tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 1.44 in.
