HYDRAULIC BOLT TENSIONERS WWW.DURAPAC.COM

e 1 2 tensioner instructions i

1) The bolt tensioner is fitted
over the stud
BOLTING SOLUTIONS ? 3 4 3) The stud’s nut is wound down
2) hydraulic pressure is applied
to the tensioner which then
stretches the stud

against the joint face
4) Pressure is released and the
tool removed

i advantages of FRICTION POINT FRICTIONAL LOSS

lubrication
10%
1) Reduces the friction converted to preload
during tightening
2) Increases bolt service life Lubricated 40%
3) Decreases bolt failure in threads
during installation
4) higher friction results in Lubricated 50%
less conversion of torque at nutface
to preload
