A537 Cl 1 plates API 650 insulated tanks
API 650 is the standard for welded tanks for oil storage. It specifies the design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 API 650 insulated tanks is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI, used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API 650 insulated tanks API 650 tanks with diameters between 8'-300', suitable for refineries, terminals, pipeline facilities and other customers.
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 650 insulated tanks roof and sidewall.
When the day light gradually decreases, the temperature of oil in the API 650 insulated tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API 650 insulated tanks will also decrease. When the pressure in the API 650 insulated tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API 650 insulated tanks through the open vacuum valve, which is the "suction" process of the oil tank.
