API standard 650 self anchored flatbottom tanks greater than 200 ft in diameter

For areas with high groundwater levels, the operator should take anchoring and anti-floating measures for buried horizontal API standard 650 self anchored flatbottom tanks oil tanks; API 650 oil tanks can be used for heavy fuel oil, heaters are separately designed, and buried tank material outlets are installed with bottom valves and connections. consider.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.

Soil Structure Interaction: Soil structure interaction per API 650, Section E.6.1.6 may be used for OLE design providing the damping ratio does not exceed 10 %.
Allowable Stresses
Design allowable stresses shall be per API 620 large welded steel storage tank, Section Q.3.3, including the 33 % increase permitted for earthquake loads.
Self-anchored Inner Tank
The anchorage ratio for a self-anchored inner tank, J, shall not exceed 1.0 for the OLE design combination to limit uplift and stresses in the annular plate and corner weld.
Foundation Stability
The overturning ratio defined in API 650, Section E.6.2.3, Equation (E.6.2.3-1) shall be equal to or greater than 3.0 for the defined OLE event.

Generally, the building area temperature of the API standard 650 self anchored flatbottom tanks should be considered before the tank design and construction. The temperature in the API standard 650 self anchored flatbottom tanks building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the API standard 650 self anchored flatbottom tanks, the higher the corresponding pressure and the more volatile loss.
