Calibrating torque wrenches and pressure gauges of hydraulic power packs improve the accuracy of the amount of torque applied on a given fastener. Calibration ensures that the torqueing tool has applied the right amount of force to fasten a bolt accurately. Similarly, calibrating hydraulic the pressure gauges of hydraulic power packs to ensure that the pump is providing the required pressure to the torqueing or bolt tensioning tool. As tools and pumps age, it may over tighten or loosen fasteners, that can cause the bolt to deform or break. Therefore, Calibration helps maintain the accuracy and consistency of the tool and pump.

 

Why Calibrate?

  • To ensure that the tool is making persistent measurements.
  • To ensure the quality of the torque wrench and hydraulic power pack has not deteriorated and still maintains accuracy.
  • Ensure peak performance of the bolting tool and bolt tensioning tool pump, when operational.
  • To test a new product.
  • Ensure employee and plant safety.
  • To maintain industry and government standards.

 

When to Calibrate your Torqueing Tool, Pressure Gauge? And How often?

  • Abide with the manufacturer’s recommendation of calibration to understand the frequency of calibration required.
  • Calibrate before starting any large scale projects/ new jobs which require heavy usage of your torqueing tools.
  • Calibrate your tools after repairs or replacement of spares.
  • To meet certification standards.
  • Carry out a scheduled calibration frequently if tool and pump dependency is too high.
  • It is recommended that at least calibrate annually for safe operation.
