Pipe Bending Machine 32-42”
One source. One proven solution.
CRC-Evans is the industry’s largest manufacturer of
pipeline construction equipment. Designed in-house to
precise customer specifications, our welding machines,
pipe bending equipment, end prep equipment, clamps,
padding/crushing equipment, weighting systems, and
laybarge equipment have been used to complete more
than 60,000 miles of pipeline in more than 100 countries.
CRC-Evans builds today’s most comprehensive line of
onshore and offshore pipeline construction equipment.
All equipment is manufactured within a Quality
Management System certified to the internationally
recognized ISO 9001:2008 standard and CRC-Evans’
own Quality Policy.
For pipe from 32” (813mm) to 42” (1,067mm). CRCEvans state-of-the-art bending machines.
 Hydraulic controls give one operator complete
command of all machine operations from a
convenient platform.
 Hydraulically driven winch moves pipe through the
machine. Pipe moves easily on contoured rollers.
CRC-Evans Pipeline Equipment
 Calibrated indicator rod allows operator to make
consistently uniform bends.
 Pin-up shoe automatically grips pipe to prevent
distortion.
 Conversion to another pipe size within machine
range is made simply by fitting an alternative
bending set.
 Machine is capable of bending all grades of currently
available API-5L pipe within its range.
 Machine frame constructed from high-strength steel
to ensure long life without fatigue failure.
 Unitized construction makes for easy maintenance
and repair.
 Towing eye is attached to hydraulically actuate stiff
back and may be raised and lowered to facilitate
attachment to towing tractor.
 Machine may be towed on the right-of-way by a
suitable tractor (normally the side boom feeding the
pipe to the bending machine).
 For each pipe size to be bent, a bending set,
bending die, mandrel, and bending belt are required.

Notes Bending Tables:
 For wall thickness greater than shown please
contact CRC-Evans Engineering Department.
 Figures are recommendations only and do not
constitute a warranty.
 All bends shown include the use of CRC-Evans
bending mandrels. Figures given are “average”
and will vary due to :
 The wall thickness of the pipe.
 Actual (as opposed to nominal) yield of the pipe.
 Skill of the operator handling the bending machine
and mandrel.
 Origin of pipe (pipe mill, plate mill, etc.) and quality
of pipe.
 Type of pipe. Spiral seam pipe will normally accept
only 75% of recommended bend.
 Type of die and/or bending set being used
(e.g., polyurethane lining or special radius dies).
Normal Unbend Tangents
An unbent end (tangent) is produced at each end of the pipe where the pipe contacts the stiff back and pin-up.
A pipe support may be required at each end of the pipe on pipe diameters of 48” and larger.
