ASTM A1011M sheets API standard 650 welded storage tanks
According to API standard 650, the stairs used for API 650 petroleum storage tanks or thermal insulation tanks should be double longitudinal beams supported by a minimum of ribs. If the gap between the API standard 650 welded storage tanks tank shell and the stringer of the API 650 petroleum storage tank exceeds 200mm, handrails should be provided on both sides of the stairs. Unless otherwise specified, according to API standard 650 welded storage tanks ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.
When encountering heavy rain or continuous heavy rainfall, the safe operation of API standard 650 welded storage tanks will be affected. For example: the API standard 650 welded storage tanks is submerged, the oil unloading valve and the flame arrester valve are broken by water and the oil tank leaks. The oil tank area must do emergency work to prevent rainstorm to ensure the safety of the oil tank. Here are some safety protection measures for API standard 650 welded storage tanks in heavy rain.
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 welded storage tanks roof and sidewall.
