Orbitalum BRB 4 Electric Boiler Tube Prep Machine

Orbitalum BRB 4 Electric Boiler Tube Prep Machine

The BRB 4 boiler tube beveling machine by Orbitalum is a handheld end prep beveller designed to produce highly repeatable weld preps, and is ideal for the continuous production needs of the fabrication industry, particularly with optional Pneumatic Auto Clamping. It's capable of simultaneous facing, beveling, and counterboring tubes and pipes (including high alloy steel) from .752” (19mm) up to 4.37” (111mm) I.D. and a .59” (15mm) wall thickness (depending on configuration). Available in Electric, Pneumatic, and Pneumatic Auto Clamping models with standard or NC style clamping.

  • Handy and compact design
  • Precise and reproducible weld preparation
  • Fast application with the BRB Pneumatic/Auto by means of pneumatic ­clamping, ideal for continuous production e.g. boiler and heat exchanger applications
  • High performance and lightweight
  • High-performance coated tool bits with up to 4 cutting edges
  • Quick clamping system for tools with easy adjustment
  • Adjustable air outlet
  • Easy to change tools
  • Tools adaptable on all BRB machines
  • Possibility to retrofit to previous BRB models to BRB Pneumatic/Auto and to the new clamping system "NC"

The BRB machines are available in the following drive versions:

  • Electric: 230 V, 50/60 Hz EU or 120 V, 50/60 Hz EU/US
  • Electric drive with single-phase AC motor, protection class II (double insulated),
  • Built-in electronic variable cutting speed
  • Pneumatic: Pneumatic power drive. Manufacturer’s warranty can only be given when ­using a mobile air unit. We recommend the mobile air unit from ­Orbitalum Tools (Code 790 093 060).
  • Pneumatic/Auto: Pneumatic multi-disc motor with additional pneumatic clamping ­system. Time is of the essence when installing or repairing boiler pipes, the new pneumatic clamping system greatly reduces the time to both clamp and release the machine, improving efficiency. The machine centers itself on the inside diameter of the pipe and then clamps automatically by using the toggle switch, likewise the toggle switch releases the clamping after the machining operation. This is why the BRB with automatic pneumatic clamping is ideal for continuous production e.g. boiler and heat exchanger applications.
