Internal structural members of API standard 650 partially anchored liquid-storage tanks

API standard 650 partially anchored liquid-storage tanks Oil measuring hole: The oil measuring hole is used to measure the height, temperature and sampling of the oil stored in the tank, and is installed near the tank top platform. API standard 650 partially anchored liquid-storage tanks Fire extinguisher: The fire extinguisher (also known as the flame arrestor) of the oil tank is composed of a fire box, a copper wire mesh and an aluminum partition. It is installed under the breathing valve or safety valve to prevent sparks and air from entering the inside of the tank through the breathing valve or safety valve and causing accidents.

When the API standard 650 partially anchored liquid-storage tanks top shell course is the minimum thickness indicated in 5.10.4, Table 5-6 and Figure 5-6, details a – e, h and i, the minimum anchorage shall be designed for normal loads as specified by the Purchaser and by this standard. See 5.11.2.3 for the allowable stress. When the top shell course is thickened beyond the minimum thickness provided in Table 5-6 or as in Figure 5-6, details f and g, or a knuckle is used, the minimum anchorage shall be designed for three times the internal design pressure. The allowable stress for this loading is 90% of the minimum specified yield strength of anchorage material.

API 650 storage tank, double-layer oil tank environmental protection advantages: ordinary single-layer steel API standard 650 partially anchored liquid-storage tanks oil tank is corroded by underground water and gas and electrolytic corrosion because it is buried underground all year round. The API 650 tank has a double-layer structure with a gap of 0.1 mm. The API standard 650 partially anchored liquid-storage tanks outer layer of FRP ensures that the leakage will not directly leak into the soil and water source.
