Improve your bolted connections
Correct installation and continuous inspection of critical bolted joints is crucial to the integrity of the assets, but it can also be very expensive. When installing new bolts or evaluating existing bolts, ultrasonic measurement has proven to be a very accurate and cost-effective solution as part of determining the lifespan of wind turbines.
This is how it works
Bolt-Check can be used when installing new bolts and when evaluating existing bolts as part of determining the lifespan of wind turbines. By using the ultrasonic measurement tool, you can measure the length of a bolted joint. The ultrasonic device measures length similar to how a sonar measures distance from a ship to the sea bed. After a tightening procedure, you can measure a change in length, which can be calculated into a clamping force.
With Bolt-Check, you achieve the right alignment of bolted joints efficiently and in a controlled manner. The tool is suitable for most bolt types and requires no special pre-treatment of the bolts. It can play an important part in maximising the operating time of the turbine and at the same time minimising failure.
Approved method for measuring bolt tension
Bolt-Check has received a component certificate from DNV-GL, which means that Bolt-Check can be equated with torque and tension tools for service inspections of wind turbines.
Bolt-Check is therefore an approved method that can verify whether the bolt has the correct clamping force. This helps save depreciation of clamping tools, repair and service of tools. It also contributes to a less time-consuming operation. Compared to the traditional tools, Bolt-Check is physically much smaller and easier to handle. This limits heavy and strenuous work.
