ASTM A131 plates API 650 liquid-storage tanks

The advantages of API 650 floating roof tanks have obvious environmental and economic benefits: in a specific climate environment, according to historical data, the economic value of the API 650 liquid-storage tanks floating roof tanks in API 650 due to the reduction of oil and gas volatilization within 3-6 months is equivalent The installation and purchase cost of the API 650 liquid-storage tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.

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.

Proper use of API 650 liquid-storage tanks and precautions:
1. The API 650 liquid-storage tanks must be used within the safe height range;
2. Check before use to ensure that the safety valve and breathing valve are flexible and easy to use;
3. The explosion-proof and fire-proof safety measures for oil tanks are implemented effectively;
4. The oil level in the API 650 liquid-storage tanks should be accurately measured when receiving and delivering oil, so as to prevent overflow or empty;
5. In the process of receiving and sending oil, the flow rate of oil should be controlled, and it should not be too fast to avoid electrostatic accidents.
