API standard 650 self-anchored storage tanks gauging platform

Our quality control department will do inspection for details of the steel materials API standard 650 self-anchored storage tanks before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

The main contents of safety inspection for atmospheric storage tank, API standard 650 self-anchored storage tanks are to see whether the tank foundation is sunk, whether the tank is corroded, whether there are cracks in the tank body and bottom, whether there is concave convex phenomenon on the top and wall of the tank, whether the accessories of the storage tank are in good condition, etc. After the API standard 650 self-anchored storage tanks safety inspection and detection, the defects found in the tank should be handled according to the inspection rules in time to ensure the normal and safe use of the storage tank in the later stage.

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 standard 650 self-anchored storage tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 1.44 in.
