API 650 aboveground oil storage tanks examination, inspection, and repairs

Application scope of API 650 petroleum storage tank:
1. API 650 aboveground oil storage tanks Working pressure: atmospheric storage tank;
2. API 650 petroleum storage tank working temperature: -30℃～150℃;
3. API 650 petroleum storage tank liquid medium: various oil products, including naphtha, gasoline, diesel, kerosene, crude oil, fuel oil, heavy oil, benzene, xylene, methanol, ethanol;
4. API 650 petroleum storage tank volume: current design considerations generally do not exceed 10,000 cubic meters.

Static storage loss is also known as "small breathing" consumption. The rise and fall of the temperature in the API 650 aboveground oil storage tanks leads to the increase and decrease of the pressure in the tank, which makes the mixed oil gas discharged from the tank, and the external air is sucked into the tank, resulting in the oil consumption. Fluid level loss is also called "big breathing" loss. It is the oil consumption caused by the change of gas space volume in the API 650 aboveground oil storage tanks during the oil receiving and sending operation, which causes the mixed oil gas to be discharged out of the tank, and the external air is sucked into the tank, resulting in the oil consumption due to the change of liquid level height.

Protection of Plates during Shipping and Storage
Plates shall be adequately protected during shipping and storage to avoid damage to API 650 aboveground oil storage tanks material plate surfaces and edges from handling (scratches, gouge marks, etc.) and from environmental conditions (corrosion, pitting, etc.).
Plates shall be protected from moisture or stored in inclined position to prevent water from collecting and standing on surface.
