120ft diameter API 650 self-anchored flat-bottom tanks

The characteristics of the API 650 self-anchored flat-bottom tanks internal floating roof structure of API 650 petroleum storage tanks: the inner floating roof or inner floating plate refers to the floating roof that floats on the liquid surface of the oil tank with the oil and liquid up and down. The API 650 self-anchored flat-bottom tanks inner floating roof is used to cover the liquid. The surface is currently recognized as the most ideal and most economical and practical way to reduce oil evaporation loss.

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

Structural shapes of 9% and 5% nickel steel may be furnished to the chemical and physical requirements of ASTM A353, A553, or A645. Physical tests shall be in accordance with the requirements of ASTM A6.
API 650 self-anchored flat-bottom tanks used Piping, Tubing, and Forgings
Material used for piping, tubing, and forgings shall be compatible in welding strength, and thermal expansion coefficient with the tank shell material. In addition to the specific requirements of this appendix, all piping within the limitations of 1.3.2 shall fulfill the minimum requirements of ASME B31.3.

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;
