API 650 SUG III tanks backing

API 650 SUG III tanks foam generator is a fire extinguishing device fixed on the oil tank. One end of the foam generator is connected to the foam pipeline, and one end is flanged on the top layer of the API 650 SUG III tanks wall. Fire extinguishing foam flows through the air intake entrance of the fire foam chamber, inhaling a large amount of air to form foam, and breaking through the insulating glass into the tank (glass thickness is not greater than 2mm), so as to achieve the purpose of fire fighting.

The increased uplift described in API Standard 620 tank Appendix Q is intended to apply to the size of the ringwall and foundation but not the anchorage. For tanks with an internal design pressure of 1 lbf/in.2 gauge and over, the uplift, if any, shall be calculated under the combined conditions of 1.25 times the internal design condition plus the design wind load on the API 650 SUG III tanks shell and roof.

The liquid level of API 650 oil storage tank is covered by floating roof. The storage liquid of API 650 oil storage API 650 SUG III tanks tank is isolated from the air, reducing air pollution, fire and explosion hazards, and easy to ensure the quality of liquid storage. It is especially suitable for the API 650 SUG III tanks storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.
