Bolt Tensioning

In-Situ Bolt Tensioning Tools and Bolt Tensioning Services

The most common method for joining assemblies in mechanics is by means of bolts and the most common problems of the industry when it comes to machines are serviceable by bolt tensioning solutions.

Joint failures account for 30% caused mainly by under tightening and over tightening. Combine that with irregular tightening and the result would be an uneven tension load that result in the rigidity of the assembly being compromised. This is due to shear stresses, bending moments and fatigue. We offer bolt tensioning services to give solutions to your bolt-related problems.

Several methods in bolt tensioning have already been applied. Here at the In-Situ group we aim to reduce, if not eliminate the problems often caused by improper bolt tensioning with the aim of saving costs for the customers that is always relative to downtime caused by breakdown, shutdowns and even accidents.

Bolt tensioning equipments

Bolt Tensioning Hydraulic Torque Wrench

up to 135mm nut AF (bolt size 3-1/2”), 30,000 ft.lbs torque capacity.

This hydraulic torque wrench is applied directly to a nut which is applied thru an impact socket to provide bolt tensioning solutions. Unlike the usual torque wrenches, this bolt tensioning tool could be calibrated to apply a controlled torque during bolt tightening to ensure that the problems that are usually encountered with improper torque loads are reduced. Due to the uniformity of torque applied during fastening, the hydraulic torque wrench also eliminates the problems that are usually encountered with conventional wrenches during bolt removals.

Bolt Tensioner

1” to 3-1/2” bolt size

In bolt tensioning, it is imperative to have a control in bolt tightening loads without which, errors could develop proving very costly when the expected performance of the joined assemblies fails to function as expected.

Bolt Tensioning Torque Multiplier

up to 2,000 ft.lbs capacity

Controlled torques translates to controlled power and are very handy when it comes to bolt tensioning operations. Mechanical applications in heavy machine parts could be used successfully and could provide longevity to machine parts where joints bolted and sealed with the correct power.

Bolt Tensioning Manual Torque Wrench

up to 600 ft.lbs capacity

This high-quality, accurate and reliable manual torque wrenches for commercial and industrial bolt tensioning applications.
