Pneumatic Wrench Calibration

You are here:
  1. Home
  2. Torque Calibration
  3. Pneumatic Wrench Calibration

Pneumatic mutilpliers or nutrunners as they are often referred to, are basically an air operated torque wrench capable of extremely high torque.

To maintain optimum performance and safety these should be serviced and calibrated on a regular basis with service intervals depending on the type of use and environment the tool is subjected to.

When calibrating the nutrunners it is preferable to do this with the corresponding filter regulator unit supplied with the tool. Calibration is then carried out on a joint simulator to simulate the working conditions of bolted joints using a compatible torque transducer and torque display.

Regular servicing will improve the performance and durability of the nutrunner which is essential for the high torque environment in which they are used.

All calibrations are supplied with a torque versus air pressure calibration chart and table to show the air pressure the operator need to select to achieve a desired torque output from the tool.

FAQs
  • What is Torque?

    Torque is a “turning” or “twisting” force and differs from tension, which is created by a straight pull. However, we use torque to create a tension.

  • How does Torque Work?

    As the nut and bolt are tightened, the two plates are clamped together. The thread angle in the bolt converts the force applied into tension (or stretch) in the bolt shank. The amount of the tension created in the bolt is critical.

  • Why Use Torque Products?

    A bolt tensioned properly works at its optimum efficiency and will resist coming undone. However, if the tension is too low, the nut could vibrate or work loose. If the tension is too high (overstretched), the bolt could break. Every bolt has a correct optimum torque/tension figure for each fastening application. It is important to have these figures available so that the end product will be safe, efficient and economical.

  • How to Measure Torque?

    Torque is the result of multiplying the value of Force applied by the Distance from the point of application.
