The TB3 Prepper is a rugged, portable, machine designed for the removal of tube-to-tube sheet welds in heat exchangers and boilers.
This bevelling machine can also be used for facing and bevelling the ends of tube and pipe for general welding and fabrication processes.
Utilising a torque-reacted locking system and durable taper roller bearings, this end preparation lathe is highly stable.
The machine is supplied with hand-wheel feed as standard. A ratchet feed mechanism which is designed for weld removal applications where space may be limited is available as an option.
