Dyna Torque/Numax Pipe Facing Machines are the fastest cutting, most versatile and
user friendly machines on the market today. Years of experience and the highest quality
components are incorporated into every unit.
Clamp sections can be changed easily in the field if necessary. In a matter of minutes, pipe
size changes can be made simply by unbolting one clamp, sliding it off, and sliding the
other size on and re-bolting. Hydraulic connections connect and disconnect internally
during change-out procedure - no hoses or fittings to mess with and no hydraulic spillage
due to Dyna Torque/Numax’s patented "boss" connecters.
Dyna Torque/Numax Power Units supply the power needed to operate the Pipe Facing
Machine. Available in diesel or electric drive, each unit is self-contained and includes
everything necessary to power the Pipe Facing Machine. All components are skid
mounted and consist of a Prime Mover, Hydraulic Pump, Hydraulic Oil Reservoir,
and Hydraulic Hoses to transfer power to the Pipe Facing Machine.
Pipe Facing Machines
Sizes 6 in. to 60 in.
Standard Features
• Quickly adjustable from 6" (152.4 mm) through 12" (323.9 mm) pipe sizes.
• Repetitive concise bevels.
• Easily sets up to any bevel configuration (stick electrode including modified "J" bevel
configuration (stick electrode including modified "J" bevel, any automatic welding bevel
and transition bevels).
• Brush adapters eliminate both internal and external manual buffing, grinding or sanding.
• No bevel set up to change pipe sizes. Cutting heads move as one unit, eliminating
bevel reset up time.
Hydraulic Power Units
Diesel Engine or
Electric Motor
Standard Features
• Diesel Units come equipped with an electric start, water cooled, Caterpillar diesel engine.
• Electric Units contain a heavy-duty industrial motor, disconnect switch with thermal
protection, and an On/Off switch for operation. Electric Units are available in a variety
of voltages and may be ordered as 50 Hz or 60 Hz.
• All units come equipped with a dual-action Parker hydraulic oil pump and a heavyduty Parker oil filter.
Dyna Torque/Numax Pneumatic Internal Lineup Clamps assure rapid, accurate alignment
of two joints of pipe during the welding operation. Front and rear heads operate
independently to lock the clamp into position. Specially designed shoes on each
head exert pressure uniformly around the inside circumference of the pipe to maintain
necessary alignment. Each Lineup Clamp is quickly and easily adjusted for different
pipe wall thickness. Clamps 16" (406.4 mm) or larger are self-propelled with powerful
air motors that drive the clamp forward through the pipe to the next joint.
Offshore projects call for the Dyna Torque/Numax Purge & Backup Clamp. Its reinforced
structural steel frame deftly handles the large-diameter, heavy-wall pipes typical of
offshore projects. All functions are wirelessly controlled by the stalking machine
operator, which decreases the time for fit-up and eliminates errors such as lowering
of the copper shoes during a welding cycle. Our Purge & Backup Clamps are perfect
for Spoolbase applications.
Dyna Torque/Numax clamps have been proven in thousands of miles of pipeline
construction, under the most extreme field conditions.

Dyna Torque/Numax introduces its LoneStar automatic welding system developed by
utilizing over 60 years combined experience in the pipeline welding industry, providing
an excellent knowledge of welding processes and techniques. The LoneStar system
integrates the latest in software development and microprocessor technologies combined
with innovative device design to offer a compelling digital welding solution.
The LoneStar welding system provides pipeline constructors with advantages over
traditional welding processes:
• More consistent weld quality through verifiable repeatability.
• Microprocessor control of all welding parameters reducing weld repairs and labor costs,
virtually eliminating the risk of human error in equipment operation.
• Reduced dependency on experienced operators.
• Elimination of interference with procedural welding parameters.
• Real-time logging of welding parameters.
Today's endless demands for higher quality and lower costs require in-depth, specific, and
highly-detailed production data. The LoneStar automatic orbital welding system provides
real-time information enabling efficient management of the robotic welding line. Project
managers can analyze raw production data in an unbiased environment, unfiltered by
welders on the line.
The user-defined access to production information allows managers to conduct comparative
analyses of quality and throughput benchmarks, as well as maintain tighter hold on costs
via inventory and machine utilization assessments.

The soil excavated from a pipe trench can be screened back into the excavation by our
Screener Crusher. For the builder and contractor, this new working method in pipeline
padding/back filling means significant savings in time and material costs, since the
excavated soil does not have to be transported away and replaced with new soil.
In addition, the process minimizes the building of site roads, which means there is
less traffic at the site. At the same time, the reducing gravel reserves are saved.
Besides saving time and construction costs, natural resources are also preserved.
