API standard 650 cylindrical liquid-storage tank material requirements
The thickness of the overburden on the top of the API 650 oil tank should not be less than 0.5m. The surrounding backfill with clean sand or fine soil should be no less than 0.3m thick; the API 650 oil tank API standard 650 cylindrical liquid-storage tank operation platform ladder selection unit is considered in a unified manner. The buried operation well is designed for buried horizontal oil tanks, and the two are compatible.
In this project, a cylindrical tank 62 ft 6 in. in diameter is designed for an internal pressure of 4 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 steel with appropriate grades for different plate thicknesses in accordance with Table 4-1 for a design metal temperature less than 65°F but not less than 25°F. No corrosion allowance is required for any portion of the tank. The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The roof is a single lap-welded spherical dome with an internal radius of 50 ft and a thickness of 1/4 in. The maximum design liquid level is 6 in. below the plane of the juncture of the tank API standard 650 cylindrical liquid-storage tank roof and sidewall.
The hot weather in summer brings great security challenges to the vertical oil storage tanks, API standard 650 cylindrical liquid-storage tank standing outdoors. We must find some simple and effective methods to protect the API standard 650 cylindrical liquid-storage tank in order to make them safely spend the summer. As a API standard 650 cylindrical liquid-storage tank manufacturer, in order to reduce the direct sunlight rate of the vertical oil tank, reduce the temperature change of the oil tank, and reduce the evaporation loss of the oil tank, we usually adopt the measures of applying sunscreen paint and washing with warm water.
