API Std 650 stainless steel storage tanks contract
storage tanks API Std 650 stainless steel storage tanks designed in accordance with the rules and guidelines of API 650 are called API 650 storage tanks. API 650 is a control rule for welded storage tanks that work normally in the normal pressure range.
The impact tests for API 620 welded storage tanks used pipe (including structural members made of pipe), bolting, and forgings, shall be in accordance with ASTM specifications ASTM A333 (seamless only) pipe, ASTM A36 Mod 1 plate, ASTM A131 Grades CS, D, and E steel plate, ASTM A633 Grade A CSA G40.21 Grades 38WT, 44WT and 50WT high-strength low-alloy structural steel plate, ASTM A350 carbon and low alloy steel forgings, and ASTM A320 Grade L7 bolts.
The main reason of "small breathing" loss of API Std 650 stainless steel storage tanks is the change of atmospheric temperature. When the temperature rises with the increase of solar radiation from dawn, the temperature of oil in the API Std 650 stainless steel storage tanks also changes, resulting in the acceleration of evaporation speed and the increase of evaporation pressure. When the pressure exceeds the positive pressure rating of the breathing valve, the oil-gas mixture in the API Std 650 stainless steel storage tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.
