API Std 650 ground-supported liquid storage tanks bearing load

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 Std 650 ground-supported 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 Std 650 ground-supported liquid storage tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.

Oil tank is an important equipment for oil storage. The common API Std 650 ground-supported liquid storage tanks is composed of foundation, bottom plate, wall plate, top plate and accessories. The types of oil tank are various, which can be divided according to the characteristics of material, installation position, storage oil, use, appearance, structure and volume of oil tank. The commonly used materials of metal oil tank are stainless steel, carbon steel, alloy steel, etc.
