When tensioning a bolt to a specific torque, it is important to be aware of the factors that must be in place to avoid undertightening or overtightening the bolt. A bolt that is not correctly tensioned to a torque can have major consequences.
Hydraulic torque tensioning of bolts is still the method that is used in the vast majority of places when we talk about torque tensioning over XXX Nm. Torque tensioning is the same, regardless of whether it is hydraulic tensioning or using electric/battery powered nutrunners. There are, however, some precautions and principles that must be observed.
We train customers and partners about correct torque tensioning, because we know what the consequences would be if a bolt is either undertightened or overtightened.
The course is a combination of theory and practical training, so we ensure both an understanding of the mechanisms involved, and why the necessary precautions should be taken, just as it is important to understand torque tensioning itself from a purely practical point of view.
The course can be held in both Danish and English.
See the course dates below.
We teach the following topics in connection with correct torque tensioning
|Torque tensioning with both torque wrenches and tensioners – advantages and disadvantages of both methods|
|Basic theory behind torque tensioning|
|General knowledge about bolts, threads and their quality|
|What is the impact of stress on a bolt, and what are the consequences|
|Review of pre-tension metering|
|Theory and review of the actual tensioning process and determining the correct torque|
|What impact does friction have, and how is it handled|
|Correct grease for specific torque tensioning|
|Practical training in torque tensioning|
