Feature Description
This horizontal storage tank product is designed for storing media primarily composed of liquefied petroleum gas (propane), with a saturated vapor pressure at 50℃ less than or equal to 1.63MPa and an H2S solubility less than 7.7mg/L. The storage tank is cylindrical, consisting of a cylinder body, a head, and a saddle. The main material is Q345R. Standard nozzles include a manhole, a safety valve port, a blowdown port, an emergency water injection port, a balance port, a gas phase port, a vent port, a balance port, a gas phase port, a liquid outlet, a liquid inlet, a liquid level gauge connection, a pressure gauge connection, and a thermometer connection. The tank body is painted with silver powder or medium gray color code paint. The medium is flammable and explosive, with a loading capacity of 0.9, leaving 10% of gas phase space. The working pressure is 1.63MPa, the design pressure is 1.77MPa, the maximum allowable working pressure is 1.82MPa, and the design temperature ranges from -20℃ to 54℃. The design, manufacturing, testing, and acceptance of this product comply with the following standards and regulations: (1) TSG 21—2016 《Supervision Regulation on Safety Technology for Stationary Pressure Vessels》 (2) GB150.1～150.4—2011 《Pressure Vessels》
