4.3 General Precautions When Torquing
Bolts in turbines are always tightened to specific values.
Over-tightening a bolt may lead to the bolt being damaged or failure (breaking) during turbine operation.
Under-tightening a bolt may cause bolt to loosen during turbine operation, leading to the overload of neighbouring bolts, which may subsequently fail.
It is important to follow the procedures described in this document to prevent personal injury, damage to bolts or equipment or bolt failure during turbine operation.
4.4 Approved Tightening Tools
Only calibrated tools may be used. The calibration due date must be checked with the date of the task.
Tools that are missing a label or that have exceeded the calibration date may not be used.
Training provider: insert photo of tool calibration label
