The design and construction for API standard 650 fixed roof tanks

API 650 petroleum storage tank body design is mainly the design of tank bottom, API standard 650 Fixed roof tanks tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API standard 650 fixed roof tanks storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.
