Internal components of API 650 unanchored flat-bottom tank

The specifications used in the design of large oil tanks, API 650 unanchored flat-bottom tank mainly include American Petroleum Institute Standard API 650, Japanese Industrial Standard JIS B8501, British Industrial Standard BS2654 and Chinese National Standard GB50341 from a global perspective. The formulas used in each specification are based on the hoop stress in the membrane theory. Each specification is based on the performance characteristics of materials and the construction technology level of their respective countries to determine the allowable stresses and weld coefficients. Therefore, the calculation results of tank wall thickness of API 650 unanchored flat-bottom tank with the same volume are sometimes quite different according to different specifications.Welding of API 620 Steel storage tank Primary Components
The following primary components shall be joined with double butt-welds that have complete penetration and complete fusion except as noted:
Longitudinal and circumferential shell joints and joints that connect the annular bottom plates together. When approved by API 650 unanchored flat-bottom tank Purchaser, these may be welded from a single side provided temporary non-fusible backing is used with complete penetration and complete fusion. Both sides of the joint shall be 100% visually examined as specified in 7.15.5.API 650 tanks in which liquid fluids are stored and designed to withstand atmospheric pressure operation, less than 18 kPa, or internal pressures not exceeding the weight of the API 650 unanchored flat-bottom tank roof, with temperatures no higher than 93, 3 C are included in the scope of this design code.Based on the principle of “sincerity and win-win cooperation”, our company keeps forging ahead.
