66m diameter API 650 welded storage tanks

The most popular standards for API 650 welded storage tanks are API Std 650, JIS B8501, BS2654, GB50341, etc. The formulas used in each standard are derived from the hoop stress calculation formula of membrane theory. Combined with the stress characteristics of API 650 welded storage tanks, plus the allowable stress, weld coefficient and additional wall thickness, the wall thickness calculation formula is complete. The allowable stress and weld coefficient are determined according to the material performance characteristics and construction technology level of each country. According to different API 650 welded storage tanks standards, the calculation results of tank wall thickness are sometimes quite different.Determination of Required Capacity
The aggregate capacities required for any vent valves, pressure-relieving valves, and/or vacuum-relieving valves to be provided should be determined as follows:
a)For thermal breathing and product movement, the rules given in API 2000 shall be followed. The required capacity as the result of the product movement into the tank API 650 welded storage tanks given in API 2000, shall be multiplied by the ratio of the absolute tank pressure to atmospheric pressure (14.7 lbf/in.2 absolute).
b)For supplemental safety pressure-relieving devices to take care of extra venting capacity required in case of external fire exposure, the rules in API 2000 shall be followed.For API 650 tanks Projection from outside of tank shell to extreme face of flange - plus or minus 5 mm. API 650 welded storage tanks Elevation or radial location - plus or minus 6 mm. API 650 tanks Flange tilt in any plane, measured on the diameter across the gasket surface - plus or minus degree but not exceeding 5 mm. Flange bolt hole orientation - plus or minus 2 mm.The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions.
