Flanges with More than 24 Bolts
Sequentially tighten the first 12 bolts to a snug tight-
ness. Tighten the next 12 consecutively numbered bolts
in sequence, to the final torque. Then, apply final torque
to the first 12 bolts and the bolts not yet tightened (i.e.,
unnumbered bolts in the figure at right sure to start with
bolt “1” and move progressively around the flange in a

Evaporator Water Box Covers
Ensure that the water box head rests tightly against the
tube sheet; then snugly tighten the 26 bolts in sequential
order. If excessive tube sheet crown prevents the head
from contacting the tube sheet, tighten the bolts located
where the greatest gaps occur. Be sure to use an equal
number of bolt turns from side to side. Then, apply final
torque to each bolt in sequential order.
