API Std 650 ground supported liquid storage tanks typical joints

API 650 petroleum storage tank body design is mainly the design of tank bottom, API Std 650 ground supported liquid storage 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 Std 650 ground supported liquid storage 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.

Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API Std 650 ground supported liquid storage tanks. The mechanical cleaning of the API Std 650 ground supported liquid storage tanks can make the inside of the tank be thoroughly cleaned in multiple directions, and the cleaning quality is high, and the cleaned oil does not contain lumpy impurities. While the walls and roof of the API Std 650 ground supported liquid storage tanks cannot be cleaned in multiple directions during manual cleaning, and the cleaning quality is not easy to be guaranteed. The oily sewage collected after cleaning usually contains a lot of lumpy impurities, and these oil products are difficult to clean.

Cylindrical Oil Storage Tanks Discharge Pipes
When a discharge pipe is used on the outlet side of such relieving devices, its area shall be not less than the area of the valve outlet, or if a single pipe provides for discharge from several relief devices, its area shall be not less than the aggregate area of the valve outlets. The API Std 650 ground supported liquid storage tanks discharge pipe shall be fitted with an open drain to prevent water or other liquids from lodging in the discharge side of the valves.
Discharge pipes shall be supported so that no undue stress is placed on the valve body. Open discharges shall be placed and oriented so that the outflow is directed away from the tank and will not create a hazard over walkways, stairways, or operating platforms.
