10ft diameter API Std 650 mechanically-anchored steel tanks
Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API Std 650 mechanically-anchored steel tanks floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.
When the API Std 650 mechanically-anchored steel 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.
The structure of the API Std 650 mechanically-anchored steel tanks foundation mainly includes the insulating anticorrosion layer on the top surface of the foundation, the tank wall support, the edge retaining structure, the sand cushion, the oil and water barrier, the detection signal tube and other structures. The construction materials and requirements of each basic structure of the storage tank are different. After the structure of the API Std 650 mechanically-anchored steel tanks foundation is built in accordance with the construction requirements, the settlement of the storage tank foundation needs to be observed, and the uneven settlement value of the storage tank foundation should be within the allowable safety range.
