API standard 650 aboveground welded storage tanks plates

The safety inspection of atmospheric storage tank, API standard 650 aboveground welded storage tanks is divided into external inspection, internal and external inspection and comprehensive inspection. External inspection shall be conducted at least once a year, internal and external inspection shall be conducted at least once every three years, and comprehensive inspection shall be conducted at least once every six years. The safety inspection of large atmospheric storage tanks, API standard 650 aboveground welded storage tanks requires special attention: the parts where the liquid level often fluctuates, the parts that are susceptible to corrosion, and the parts that are deformed and worn during use should be checked.Insulation Load
For 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 aboveground welded 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.Storage tanks API standard 650 aboveground welded storage tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 petroleum storage tank detailed standard specifies the design, processing, welding, inspection and installation procedures of the storage tank.Insist on the spirit of development and indomitable entrepreneurship; the spirit of leading science and technology and striving for first-class affairs; the spirit of strict management and market development; the spirit of taking the lead in setting an example and selfless dedication; and the spirit of people-oriented and enterprise ownership.The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality API standard 650 aboveground welded storage tanks products and excellent services.
