Nominal diameter of API standard 650 liquid storage tanks

API 650 can store oil, gas, chemical, water and biofuel for some of the most common tanks in the oil industry. API 650 can store contents at a lower pressure (maximum of 2 PSI) but at much higher temperature (-40 degrees F to 500 degrees F) than the standards of API standard 650 liquid storage tanks. It can be any tank size.

In this project a cylindrical tank 75 ft in diameter is designed for an internal pressure of 0.5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade B steel for thicknesses of 1/2 in. and less.
The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The tank API standard 650 liquid storage tanks roof is a conical shape with a 2:12 slope and a 1/4 in. thickness with single full-fillet welded lap joints. The maximum design liquid level is 6 in. below the plane of juncture of the roof and sidewall.

Oil storage tank with floating roof structure: The floating roof in the API standard 650 liquid storage tanks oil storage tank can effectively reduce the volatilization consumption of oil, because the gas space on the oil liquid surface in the floating roof storage tank is small, the exhaust volume is low, and the breathing loss is very small. That can reduce the volatilization loss caused by the "big breath" of the API standard 650 liquid storage tanks. Strengthen the inspection and maintenance of API standard 650 liquid storage tanks: regularly check the sealing conditions of oil storage tanks, and check and maintain important auxiliary equipment to ensure good sealing performance.
