Birawa provide service Hydraulic bolt Tensioning & bolt Torqueing

Controlled Bolting

Controlled bolting is the process for correctly applying a known load to a mechanical joint to ensure it’s joint integrity.

As bolted joints are often one of the most common elements in industrial components, the reliability of each joint is of the utmost importance. The physics that explain fastening devices for bolting are well known, and over the years, we’ve developed accurate means of measuring and applying force to joints consistently.

Offshore and Subsea Bolting Services

We are able manage bolting for Subsea Projects supported by skilled diver and techncian.

Torque Tension Techniques

Applying torque or tension forces to mechanical connections are the two most commonly used approaches used to tighten a bolt. Torque tightening utilises the helix of the bolt thread to guide the nut down the bolt threads, which in turn applies a bolt load.

This is usually carried out using hydraulic torque wrenches. Whereas Tensioning applies a direct tensile (stretching) load to the bolt avoiding the torsional (twisting) reaction forces associated with torque.

PT. Birawa Adhi Pratama product line up to provide service of Bolting are using the latest innovations to ensure that our Bolting and Bolted Joint Integrity operations are carried out fast, efficient and above all safe! Our technicians ensure that correct bolt loads are achieved.
