API standard 650 self-anchored tank for non-refrigerated service

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

API 650 is an American standard for welding flat bottom vertical storage tanks. This API standard 650 self-anchored tank standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as API standard 650 self-anchored tank crude oil, gasoline, chemicals and water. BBN has extensive experience in API 650 tanks, from +/- 500 cubic meters of tanks produced in the factory to +/- 15000 cubic meters of tanks produced on site.

On March 17 th 2018, our Sudan customer purchased the SG295 cylinder steel coils through other country such as UAE,Turkey before they cooperate with us. After they research our regular customer in Uganda, UAE, and his friends in China, he is satisfied with our company. Our produced SG295 cylinder steel is mainly used to fabricate low temperature pressure vessels like gas cylinder. The customer is very satisfied to our API standard 650 self-anchored tank quality control and professional arrangement for the SG295 steel order.
