8. Tubesheet Installation and Support Column
The tubesheet support column assists in leveling the tubesheet and supporting the tubesheet using the following steps.
1. Lift the tubesheet with the crane and attach the upper portion of the support column to the tubesheet center pipe using the
provided 5/8 UNC x 6 threaded bolts. The holes are slotted so that the tubesheet stiffeners will come to rest onto the column
plate.
2. Lift the tubesheet with the column onto the prepared dirty-air plenum bag section assembly.
