API Std 650 SUG I tanks bottom annular-plate joints

Proper use of API Std 650 SUG I tanks and precautions:
1. The API Std 650 SUG I 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 Std 650 SUG I 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.

The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently. However, if the inner and outer tanks API Std 650 SUG I tanks are supported by a common foundation, the seismic foundation loading shall be calculated using the lesser response modification values for either the inner tank or outer tank for both tanks and a dynamic analysis shall be performed to determine the combined effect.
Allowable Stresses: For Appendix R tanks, design allowable stresses shall be per API 620 large low pressure storage tank, Section R.3.3.

The API Std 650 SUG I tanks external floating roof tank of API 650 tank has many advantages, and its application range is more and more wide. It is a kind of storage tank with a bright future. The well-designed internal floating roof tank of API 650 tank is the best and least investment method to control evaporation loss of API Std 650 SUG I tanks Fixed roof tank.
