Bostech Drilling identified the need for a more robust breakout tool than those afforded by welding a lug onto a Rigid wrench handle attached to a hydraulic cylinder.
Rigid pipe wrenches have a reduced sectional area through the threaded tail on the hook. When overloaded this section fails, releasing the considerable stored energy resulting from the component strain. This then violently projects the released part of the hook into the distance or any bodies standing in the path of its flight.
The design of the Bostech Breakout tool does not allow the significant amounts of energy to be stored, as the tool has a much larger stressed section and as such doesn’t strain to the same extent. So when failure happens less energy is released and the tool fails benignly without potentially projecting parts into the distance or into any crew standing in its path.
These tools are safe even if caused to fail. They grip much more securely than Rigid wrenches and are less prone to slipping.
