    Atmospheric fixed roof tanks. A fixed roof tank faces the risk of rupture whenever liquid is pumped into the tank or as a result of vapor pressure changes caused by significant thermal changes. During these instances, the pressure/vacuum relief valve protects the tanks from [mask]Standard Practice for Examination of Liquid Filled [ppe]5.1 General This procedure is used for evaluation of the structural integrity of atmospheric storage tanks. The AE method can detect flaws which are in locations that are stressed during pressurization. Such locations include the tank wall, welds attaching pads to the tank, nozzle attachments, and welds attaching circumferential stiffeners to the tank.

    Tanks L/d Ratio Industrial Professionals Cheresources

    In my practical experience I haven't seen large atmospheric storage tanks with L/D ratios greater than 1.2 1.3. Many engineering companies generally go by a rule of thumb of L/D of 0.8 1.0 for large atmospheric storage tanks. But I would like to emphasize that, do your engineering and economic evaluation before deciding on the L/D ratio.[mask]A Comparison of Steel Tank Designs[ppe]Steel tanks offer superior quality storage solutions to industries and organizations.
