ASME Horizontal Vessel Analysis: Stresses for the Left Saddle(per ASME Sec. VIII Div. 2 based on the Zick method.)
Horizontal Vessel Stress Calculations : Operating Case
Note: Wear Pad Width (505.00) is less than 1.56*sqrt(rm*t)and less than 2a. The wear plate will be ignored.
Minimum Wear Plate Width to be considered in analysis [b1]:= min( b + 1.56*sqrt( Rm * t ), 2a )= min( 230.000 + 1.56*sqrt( 1611.0000 * 22.0000 ), 2 * 1800.000 )= 523.6863 mm
