Bolted Joints are critical in all major industrial applications but quite often appropriate loading is miscalculated during the design to installation period and maintenance/ shutdown periods. Very often these bolts tend to loosen due to heavy vibrational impacts and loads.

The desired load needs to be applied on a bolted joint either through-bolt tensioners or torque wrenches during shutdown or servicing to tighten them and maintain joint integrity.

During maintenance; the same tool is used to tighten all bolts which is a tedious and time-consuming task; whereas bolt elongation measurement will save a lot of time.

Let me explain Why Bolt Elongation Measurement is critical for all industries:
