API Std 650 open top welded storage tanks for small internal pressures
Volatilization is the characteristic of oil. Under normal temperature and pressure, as long as the oil is in contact with air, the surface will volatilize. Through scientific analysis and summary, the causes of oil volatilization loss in API Std 650 open top welded storage tanks are: natural ventilation loss, static storage loss, dynamic liquid level loss. In the use of API Std 650 open top welded storage tanks, static storage loss and dynamic liquid level loss are common losses.

API 650 petroleum storage tank body design is mainly the design of tank bottom, API Std 650 open top welded 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 open top welded 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.
