API 650 storage tank roof structure

In API 650 oil storage tank, when the mixing ratio of combustible medium and air reaches a certain limit, it is easy to cause explosion. Therefore, it is necessary to add API 650 storage tank external floating roof to open cylindrical steel API 650 storage tank tank. At present, the external floating roof is most suitable for large-scale API 650 oil storage tank in China, ranging from 20000, 30000, 50000 cubic meters to 100000 cubic meters.

The cleanliness of the API 650 storage tank has a great influence on the safety of the tank and the quality of the oil stored. Keeping the API 650 storage tank clean can slow down the corrosion of the tank wall and reduce the pollution to the oil. If the inside of the API 650 storage tank is not cleaned all the year round, a lot of rust and metal impurities will be produced in the tank. These impurities will cause the oil to slowly oxidize and deteriorate. The impurities mixed into the oil will also block the filter and oil circuit, causing oil supply failure.

The API 650 storage tank outer wall shall be designed for the purging and operating pressure of the space between the inner and outer tank shells and for the loading from the insulation, the pressure of wind forces, and the roof loading.
The outer tank bottom, shell, and roof shall have a minimum nominal thickness of 3/16 in. (7.65 lbf/ft2) and shall conform to the material requirements of Q.2.3.
