API standard 650 ground-supported liquid storage tanks supported cone roofs

Under the condition of static storage without receiving and sending operation, the temperature of gas space, evaporation rate, depth and pressure of vapor in the API standard 650 ground-supported liquid storage tanks will change with the change of temperature and pressure in a day. The oil loss caused by the process of discharging oil vapor and inhaling air gas is called "small breathing" loss, which is also called static storage loss of oil tanks.

For all API 620 crude oil tank other materials, the impact test temperature shall be at least 30°F colder than the design metal temperature. Alternately, materials impact tested at the design metal temperature or lower with Charpy impact test energy value of 25 ft-lb (average), 20 ft-lb (minimum) are acceptable for design metal temperatures above –40°F. API standard 650 ground-supported liquid storage tanks materials with an energy value of 30 ft-lb (average), 25 ft-lb (minimum) are acceptable for design metal temperatures of –40°F or lower.

The outer layer of API 650 tank is glass fiber reinforced plastic layer with a thickness of more than 2.5mm, which API standard 650 ground-supported liquid storage tanks has strong corrosion resistance and electric corrosion resistance. Special process technology is used between the two layers to make the gap reach 0.1 mm, so as to eliminate the existence of potential safety hazard from the root.
