SUG II tanks lap welded bottom joints

When Annular plate required?

Mar 10,2008 SUG II tanks lap welded bottom joints#0183;Annulars are required due to the increase rotation of the shell-to-bottom joint when using higher design stresses for these Group IV thru VI material.Likewise for Appx M tanks the increased shell tempweratures cause higher rotations at the corner joint.S,Butt welded annulars (not lap welded) are required for uplift resistance.When Annular plate required?Mar 10,2008 SUG II tanks lap welded bottom joints#0183;Annulars are required due to the increase rotation of the shell-to-bottom joint when using higher design stresses for these Group IV thru VI material.Likewise for Appx M tanks the increased shell tempweratures cause higher rotations at the corner joint.S,Butt welded annulars (not lap welded) are required for uplift resistance.Welding prep in pressure vessel fabricationPressure vessels are used in many industries to store and transfer gas or liquid under high pressure (see Figure 1).Because of the critical nature of pressure vessel applications,their welds undergo rigorous quality checks,which can include X-ray inspection and certification.
