A516 Gr 70 plates API Std 650 larger diameter tanks

Unqualified welding quality of API Std 650 larger diameter tanks is prone to hidden dangers such as oil tank steel plate cracks and leakage. To avoid this situation as much as possible, it needs to be avoided when the oil storage tank is manufactured. Scientific and reasonable measures are adopted to control the welding quality when welding the API Std 650 larger diameter tanks. How to reasonably control the welding process quality of oil storage tanks?

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 larger diameter tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 1.44 in.

The standard API 650 covers the design and calculation of different parts of the API Std 650 larger diameter tanks fuel tank. This specification is based on the knowledge and experience of buyers, manufacturers and users of API 650 welded storage tanks of different sizes and capacities. It is worth noting that the code requirements are minimal; stricter standards can be adopted for specific applications.
