Percentage wall reduction is the most frequently used procedure to obtain the optimal mechanical joint between a Tube and Tube Sheet. In order to calculate this reduction we must take into account the variances between the Tube OD, Tube Wall Thickness and Tube Sheet Hole Diameter. We must also consider the differing type of materials being used for both Tubes and Tube Sheets, however as a general rule, percentage wall reduction ranges between 4%-10%
