Hot Bolting Services

Our highly skilled technicians execute our Hot Bolting Services. We use our own in-house designed SABR™ Clamp, which is made in a certain way so our technicians can do the job fast and safe while maintaining the integrity of your assets.

SABR™ Clamp

Patriot International’s specially designed SABR™ Clamp provides an external clamping force to maintain the joint integrity whilst the Hot Bolting procedures is undertaken. Our clamps are not restricted to 4 or 8 bolt flanges. All flange sizes have the possibility for failure when disturbed during a Hot Bolt procedure. Our SABR™ Clamps are delivered in a custom made Flight Case inclusive of all components.

Why use our Hot Bolting Services/Tools?

We practice Hot Bolting for several reasons:

  • For replacing corroded or damaged bolts;

  • To minimise the time spent freeing bolts during plant shutdowns.
