CRC-Evans is a leading manufacturer
of equipment and a supplier of services
to the pipeline industry. The equipment
ranges from pipe bending machines to
pipe handling and support equipment, and
from pipe facing and bevelling machines to
internal line-up clamps. The company also
build double jointing systems for use on
land and offshore.
A highlight of the company’s range is
automatic welding systems for land
and offshore pipeline construction. This
equipment line includes single- or dual-
torch welding systems, internal welding
machines, copper backup clamps and
precision pipe facing machines.
These systems have been designed, tested,
used and continuously upgraded for more
than 35 years in every type of environment.
CRC-Evans have extensive experience in
welding X-80, X-100 and X-120 pipes, as
well as 13-Chrome, duplex, super duplex
and clad pipes.
The company provides a basic gas-metal-
arc automatic welding system designed
to make quality girth
welds while delivering
high production rates. It
can accommodate pipe
sizes from 4-60" and wall
thickness in excess of 1"
(25mm).
The system consists of three
major components. Pipe
facing machines produce a
narrow groove compound
bevel to assure near perfect
joint fit-up for every weld.
The combination internal welder/line-
up clamp travels inside the pipe to align
and clamp joint ends together, and then
automatically welds the root bead from the
inside. External welding machines make the
outer girth weld. Travelling on steel bands
fixed to the pipe, the machines accurately
complete the weld in a series of passes.
The company also offers flux-core and
pulsed gas-metal-arc systems.
In addition to the company’s extensive
onshore experience, the company has
designed and built state-of-the-art automatic
welding equipment. These offshore systems
allow the user to maximize productivity from
a limited number of welding stations. This
boosts the speed of operations, maintains
the highest level of quality, and enables the
pipeline to be built on schedule.
