API 650 carbon steel tank sample hatches

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 650 carbon steel tank 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.

API 650 external floating roof storage tanks are generally called external floating roof API 650 carbon steel tank tanks, which means that the storage tanks are externally open tanks without a dome design, and are equipped with vertical floating roofs. API 650 external floating roof storage tanks are usually used for large More than 20,000 cubic meters of open steel API 650 carbon steel tank storage tanks for storing volatile petroleum products such as crude oil, gasoline, kerosene, etc.

Square hollow section S355J2H to Turkey. In January of 2015, our customer from Turkey chose us as their supplier of seamless RHS EN10219 S355J2H with a trail order of 120 tons. They required DNV test for the MTC and each tube. DNV inspector tested all the tubes and MTC. When our customer received the reports, they gave us a second order of 852.5 tons. Since then we maintain a long time cooperation relationship.

The main advantages of the external floating roof API 650 carbon steel tank are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API 650 carbon steel tank, the production of external floating roof API 650 carbon steel tank is simple and the steel consumption is less. However, the central drainage system of external floating roof API 650 carbon steel tank should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.
