Pipe blasting and coating systems
SELMERSspecialises in themanufacture
of plants and equipment for internal and
external pipe cleaning, pipe coating and
pipe handling. Established in 1966, the
company has grown into a supplier of
comprehensive pipe coating systems,
especially of tailor made equipment for
onshore and offshore pipe coating and
pipe handling facilities.
All design and engineering work is
done in-house, with short communication
lines and optimum interfacing for
individual equipment parts. This enables
Selmers to produce reliable and efficient
pipe coating plants.
The company’s product range
comprises an extensive external multi-
layer and internal lining pipe coating
plant programme, with abrasive
blasting equipment, ovens, chromate
and acid wash units, liquid and powder
epoxy equipment and in-house made
extruders.
Last year Selmers received the 2015
IPLOCA New Technologies Award,
sponsored by BP, for its onshore
automatic vacuum field joint blaster.
This machine is part of the field
joint blasting and coating equipment
programme, used in the field for
onshore pipelines.
Selmers also has an offshore
programme aimed at pipe handling/
firing line equipment for pipe lay
vessels, field joint blasting and coating
systems (S-lay and J-lay), PU foams,
FBE and three-layer PE, as well as multi
jointing facilities for pipe spoolbases
with pipe rollers, line-up systems and
pipe pushers.
The company offers concrete weight
and cement mortar coating equipment,
rebar powder coating lines, in-situ
equipment, containerised configurations
and quality control equipment. Its range
also includes self-propelled coating
removal and re-lining machines for in-
situ pipeline rehabilitation purposes.
Equipment is offered with full project
support from first design, engineering,
construction and manufacturing up to
installation, commissioning and after-
sales services.

Detection of oblique flaws within a 30˚ range
THE pipe inspection industry has long
relied on MFL inspection methods to
detect flaws in pipes, but over the years
the limitations of MFL on detecting
oblique flaws would result in missed
flaws. Before a recent release of
enhanced technology, EMI inspections
had only allowed for detection of oblique
flaws within a very narrow range. Today,
this is no longer the case, thanks to new
flaw detection technology.
Scan Systems’ ESP upgrade to its
M-Series line is claimed to be the first
EMI inspection technology to use hall
elements in the longitudinal sensors,
which have enabled Scan Systems to
detect and repeat on flaws up to 30°
off axis on the OD surface and 20°
off axis ID surface. This is unheard
of in EMI inspections, as traditional
methods produce significant signal
reductions making it all but impossible
to reliably detect and repeat on signals
from oblique flaws greater than 7° to
10° off axis. Additionally, by utilising
hall elements Scan Systems is able to
increase the number of sensors from 16
to 64 total channels of data for better
data resolution. This allows for the
detection of much smaller flaws than the
limitations of traditional PC coils.
Not only is traditional EMI inspection
unable to repeatedly detect oblique
flaws, but even the more expensive UT
inspection equipment can only detect
oblique flaws within the specific target
angle of the probes, meaning that if
the operator has specifically set his
equipment up to reliably find flaws in
the 30° range, he will likely miss flaws
at 15° (or any other angle where it has
no targeted probe).
Scan Systems states that it is the
first to offer the ability to detect oblique
flaws in EMI inspection and because
of its unique use of hall elements and
its proprietary Digi-Pro® processing
software, if the operator is set to detect
at 30°, he will pick up flaws between 0°
and 30°, making for a more accurate
and precise pass.
With its focus on innovation and
pioneering new techniques in EMI
inspection, Scan Systems has always
set the technology standards for the
industry. As Matt Rutledge, VP/general
manager of Scan Systems, explained:
“We want to make EMI inspection
easier, more reliable, and more
precise for our customers and with our
continued advancements we’re setting
that standard higher than ever before.”
