The main reason of "small breathing" loss of API standard 650 carbon 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 standard 650 carbon 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 standard 650 carbon steel storage tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.
Advanced typical figures and typical deeds are the embodiment and symbol of API standard 650 carbon steel storage tanks enterprise spirit, outstanding ideas and vivid images, with strong demonstration, radiation and transmission effect. Without distinctive typical characters, there is no unique enterprise culture. In carrying out the construction of enterprise culture, the advanced enterprise culture should be typified. Vigorously excavate, discover, cultivate and summarize the company's API standard 650 carbon steel storage tanks advanced models.
