API Std 650 self-anchored flat-bottom tanks flat-face pipe flange

API 650 is the standard for welded tanks for oil storage. It specifies the API Std 650 self-anchored flat-bottom tanks design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI.

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

Anti corrosion of API Std 650 self-anchored flat-bottom tanks:
After using for a certain period of time, it is necessary to check the corrosion protection of the API Std 650 self-anchored flat-bottom tanks. If necessary, the outer wall of the metal oil tank should be painted with new anti-corrosion paint to ensure that the outer wall of the API Std 650 self-anchored flat-bottom tanks does not fall off and has good waterproof and rust resistance.
API Std 650 self-anchored flat-bottom tanks cleaning:
The long-term use of API Std 650 self-anchored flat-bottom tanks will produce impurities on the tank wall and deposit on the tank bottom, resulting in tank corrosion to leakage. According to the safety standard of oil tank, the API Std 650 self-anchored flat-bottom tanks shall be cleaned and derusted regularly to ensure the quality of oil stored and the safety of oil tank equipment.

The cultural construction must let the enterprise staff participate in the enterprise culture, in order to better carry on the effective dissemination enterprise idea, the sharing value system, such as the internal communication, the newspaper, the forum, the propaganda, the news announcement and so on.
