Cold Pipe Cutting And Beveling Machine
Product Introduction
Travel Cutter is secured to the pipe by a special tensioning/drive
chain, driving itself around the pipe as it simultaneously cuts and
bevels, providing a machined surface ready for welding. It's
designed for cutting and beveling all common pipe materials, wall
thicknesses and sizes from 6 inch- 72inch O.D (153-1829mm) and can
be used in a wide range of applications, including natural gas,
crude oil and radioactive environments.
Industry Application
It is widely used in long distance transport pipeline, power plant,
nuclear power, petroleum, chemical engineering, natural gas, boiler
shop, pharmacy, pipe prefabrication plant, pipeline installation
engineering, rush-repair work, etc.
Features
■ Compact Design
Easy Set-up Light weight, low profile design needs only 10"to 12"of
clearance and set up time is 30 minutes or less. Once the
adjustable drive chain is pinned together and tensioned around the
pipe the machine is ready to operate.
■ Standard Weld Prep Capability
Weld preparation detail can be achieved from common 30° and 37-1/2°bevel on standard wall carbon steel.
■ Pipe Line Maintenance
Bohyar’s Travel Cutter offers the inherent advantages of a
completely sealed and self-lubricating closed loop system. It is
particularly suited to field machining operations under the type of
hostile conditions often found in pipe line maintenance and
construction such as dirt, sand and water.

Operating Instructions
■ Connect the hydraulic hose to the valve block on the Travel
Cutter.
■ With the hydraulic supply turned on the machine is ready to cut
the pipe. Turn the valve handle on cutter valve 90° to the right.
This will make the cutter spindle motor in operation and rotate the
cutter.
■ Slowly feed the rotating cutter down until it extends through the
wall of the pipe by approximately 14mm(A maximum single cutting
depth is 14mm and it will affect the use efficiency if exceeding
14mm) This is done by turning the feed screw in a clockwise
direction. One complete turn of the feed screw lowers the cutter
4mm. Lock the cutter in position by placing the feed screw lock on
the shoulder of the feed screw and lock in place with the thumb
screw.
■ Turn valve handle on feed valve 45° to the right. This will
operate the drive motor and make the machine travel around the pipe
for a complete cut. Speed may be reduced by adjustment of the feed
valve handle (close slowly until proper speed is attained). Machine
is traveling too fast if wheel to right of cutter lifts off pipe or
if machine is vibrating excessively.
■ When the cut is completed, stop the drive motor by turning feed
valve to the left until machine stops. With the cutter still
rotating release the elevating screw lock and raise the valve to
the left 90°. Remove the cutter from the machine. Release the
tension on the drive chain by turning the chain tension screw
counter clockwise. Remove the connecting pins from the chain to
uncouple it and the machine can be removed from the pipe.
