API standard 650 self anchored flatbottom tanks shell reinforcing plates

BBN is a big team with great centripetal force. The company adheres to the tenet of "creating value for customers, creating benefits for enterprises, creating wealth for employees, and creating prosperity for society". Adhere to the strict management of factories, technology-oriented, adhering to "standard management, adhere to integrity, the pursuit of excellence, pragmatic innovation "Business philosophy, we are committed to creating a full-process, low-cost, high-quality, green and environmentally friendly stainless steel manufacturing enterprise.The API 650 oil tank stiffener ring and backing strip, if used, are primary components, and they shall comply with the requirements of R.2.1. The API standard 650 self anchored flatbottom tanks stiffener ring may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange. One rat hole with a minimum radius of 3/4 in. shall be provided at each longitudinal shell joint and ring juncture weld.In Appendix E to API 650 oil storage tank, the maximum values of inertia force, pulse pressure and convection pressure are superimposed, and tend to be conservative.In GB50341, only pulse pressure is calculated for API standard 650 self anchored flatbottom tanks tanks below 5000 m.Insist on the spirit of development and indomitable entrepreneurship; the spirit of leading science and technology and striving for first-class affairs; the spirit of strict management and market development; the spirit of taking the lead in setting an example and selfless dedication; and the spirit of people-oriented and enterprise ownership.The main reason of "small breathing" loss of API standard 650 self anchored flatbottom 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 self anchored flatbottom 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 self anchored flatbottom tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.
