Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of API 650 self-anchored tanks service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.

The main reason of "small breathing" loss of API 650 self-anchored 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 650 self-anchored 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 650 self-anchored tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.
