Bolt Tightening
The required torque value can be
calculated with KLINGER®expert gasket
selection software.
Always use the proper tools such as
calibrated torque wrench. Make 5
passes in a crisscross pattern to the
required torque as follows:
1. Tighten all nuts initially by hand
2. Torque each nut to approximately
30% of the required torque
3. Torque each nut to approximately
60% of the required torque
4. Torque each nut to full torque.
5. Apply at least one final torque to all
nuts in a clockwise direction until
all torque is uniform.
Large-diameter flanges may require
additional tightening passes.
Retightening
CAUTION--If retightening is considered
necessary, this should only be done at
ambient temperature and atmospheric
pressure before or during the first start-
up.
Never retighten compressed fiber
gaskets at higher operating
temperatures and longer operating
times.
Retorque fasteners exposed to
aggressive thermal cycling once the
joint is again at ambient temperature
and atmospheric pressure.
Re-use of Gaskets
For safety reasons never re-use a
gasket.
