API standard 650 partially anchored liquid-storage tanks for elevated temperature service

The thickness of the overburden on the top of the API 650 oil tank should not be less than 0.5m. The surrounding backfill with clean sand or fine soil should be no less than 0.3m thick; the API 650 oil tank API standard 650 partially anchored liquid-storage tanks operation platform ladder selection unit is considered in a unified manner. The buried operation well is designed for buried horizontal oil tanks, and the two are compatible.

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.

The preparatory work before the construction of the API standard 650 partially anchored liquid-storage tanks is an important part of the oil tank project. Material purchase preparation before the construction of the API standard 650 partially anchored liquid-storage tanks:
Before API standard 650 partially anchored liquid-storage tanks construction, all materials shall be purchased and prepared, and the specifications and quality of materials shall be inspected to see if they meet the construction operation requirements. Fire and rain proof measures should be taken when storing materials. Paint should be stored in a ventilated and dry place.
