API standard 650 carbon steel storage tanks convective (sloshing) period
Insulation LoadFor API 620 tanks designed and constructed with an outer tank containing loose fill insulation in the annular space between the tanks, the insulation weight shall be divided equally to the inner and outer tank wall for seismic lateral loads unless a more rigorous analysis is performed to determine the distribution. The insulation within the annular space shall not be used to calculate resistance to overturning. Insulation on the API standard 650 carbon steel storage tanks roof or suspended deck shall be applied to the tank supporting the load at the point or center of gravity of attachment and may be used to resist overturning.
Compared with the fixed roof API 650 oil storage tank without API standard 650 carbon steel storage tanks floating roof, there is no evaporation space. In principle, this eliminates the so-called "large breathing loss". Evaporation not only causes the loss of product quantity, but also affects the quality of API standard 650 carbon steel storage tanks product and pollutes the environment.
In Nov, 2018, our Mozambique customer purchased from BBN company 500 tons carbon steel Q235B steel structure for building 10 units of gas station. We have been cooperate more than 5 years for providing plate and pipes and API standard 650 carbon steel storage tanks profile as beginning, and they are very satisfied with all the received Cargo. We extend in-house cutting, welding, grinding, bending and certification and testing of our products, on client demand. If you are interested in our steel structures or steel plate price, welcome to contact us.
}Oil tank is often used to store crude oil, diesel oil, gasoline and other oil. The main structure of API standard 650 carbon steel storage tanks is composed of tank top, tank wall, tank bottom and accessories. The API standard 650 carbon steel storage tanks should be inspected after the completion of construction, and the detection methods of different structure positions are different. Tank wall inspection: for the newly built oil tank, water filling test shall be conducted to check whether the tank wall is tight, and the appearance inspection shall be conducted for the tank wall plate and weld. Tank wall thickness detection: the oil tank wall thickness is mainly detected by ultrasonic wave, with high efficiency.
