API standard 650 welded steel oil storage tanks gauge float wells

The engineering quality of API standard 650 welded steel oil storage tanks not only affects production and operation, but also affects the life safety of the staff. The factors affecting the API standard 650 welded steel oil storage tanks construction quality are all aspects, any link, any part of the problem will affect the whole project, so the quality management is paid more and more attention. How to ensure the engineering construction quality of oil tank? First, make API standard 650 welded steel oil storage tanks construction technical preparation carefully, understand the design intent, master the construction acceptance specification, and make detailed construction technical disclosure to the construction team.

The API standard 650 welded steel oil storage tanks 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.

The working pressure of the low-pressure storage tank is greater than that of the atmospheric storage tank, but its pressure is less than 0.1MPa. API 650 petroleum storage tanks are classified according to their environment: Above-ground storage tank: refers to the bottom of the storage tank at the design elevation of API standard 650 welded steel oil storage tanks and above; the bottom of the tank is below the design elevation of +0.00 but not exceeding.
