A841 Gr B plates API standard 650 self-anchored flat-bottom tanks

Our technical department plays important role in our professional communication with customers, especially those who have high technical requirements for steel materials and those who need complex further processing. Under such condition, our technician department can provide technical support in time, anylize customer design or make drawing according to customer needs rapidly, so that we can proceed smoothly. The profession of our team has won great praise of customers.The refrigerated tank primary components shall also include those parts of a single-wall or an inner tank that are not in contact with the refrigerated liquid but are subject to the refrigerated temperature. Such API standard 650 self-anchored flat-bottom tanks components include roof plates, roof manways and nozzles with their reinforcements, roof-supporting structural members, and shell stiffeners when the combined tensile and primary bending stresses in these components under design conditions are greater than 6000 lbf/in.2.storage tanks API standard 650 self-anchored flat-bottom 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.Our vasion is to create a first-class steel plate manufacturing enterprise with international competitiveness. Business Vision: Improve value with quality and become the leader in the industry. Core values: people-oriented, integrity, responsibility, excellence. Development strategy: Seek development through science and technology, and seek benefits from management. Besides, we will create a harmonious business atmosphere, unblock the channels for employees to communicate, and build a stage for various sports and talents.The most popular standards for API standard 650 self-anchored flat-bottom tanks are API Std 650, JIS B8501, BS2654, GB50341, etc. The formulas used in each standard are derived from the hoop stress calculation formula of membrane theory. Combined with the stress characteristics of API standard 650 self-anchored flat-bottom tanks, plus the allowable stress, weld coefficient and additional wall thickness, the wall thickness calculation formula is complete. The allowable stress and weld coefficient are determined according to the material performance characteristics and construction technology level of each country. According to different API standard 650 self-anchored flat-bottom tanks standards, the calculation results of tank wall thickness are sometimes quite different.
