Detection systems for copper
and copper alloys
CONTROLE Mesure Systèmes (CMS)
designs, develops and manufactures
quality and productivity solutions for all
industrial applications, for ferrous and
non-ferrous metals. Its NDT range of
products in eddy current and ultrasonic
testing methods include high-
performance instruments and systems,
probes and transducers, accessories,
and complete turnkey machines with
associated mechanics. Applications for
copper and copper alloys tubes include
detection of swimmer position inside
the tube during the manufacturing
process; eddy current defect detection
on double wall tubes; and junction
detection on copper alloys on double
wall tubes with six eddy current Zet@
Micro instruments, managing 12 lines
simultaneously.
CMS also provides other NDT systems
for tubes in steel, stainless steel, carbon
steel, titanium and zirconium. All
systems meet quality standards such as
API, ASTM and DIN, and can be used
on-line and off-line.

Fast cutting of stainless steel tube
KINKELDER’S newly developed
carbide-tipped saw blade is aimed at
setting a new standard for fast cutting of
austenitic stainless steel tube.
High-performance cutting of
300-series stainless steel tubes
with a wall thickness of 3-6mm is
the primary area of application for
this type of saw blade. Based on a
constant, conservative cutting speed
of 80m/min and constant tooth load
of 0.06mm/tooth, the new Kinkelder
Connexxioncut 4 (CX 4) saw blade
range cuts 60 x 4mm tube in under
four seconds.
With these parameters, a steady blade
life of 3 to 4m2 is reached. “That’s at least
twice as fast and twice the blade life as
what’s normally being achieved with
HSS saw blades,” said Dave Hiddink,
application engineer at Kinkelder BV.
“The cutting surface is virtually burr free,
which is similar to what can be achieved
with HSS saw blades.”
With CNC machines, which allow
applying of variable cutting speed and
variable feed rate, even shorter cutting
times are possible. “We applied cutting
speeds of 120m/min and a tooth load
of 0.1mm/tooth and achieved well over
2m2 cutting surface on tube 60 x 4mm
(3,000 cuts) without compromising the
cutting surface.”
Commenting on his own experience,
Mr Hiddink said, “While cutting 3,000
tubes 60 x 4mm normally takes two
shifts when using a HSS saw blade,
the CX 4 saw blade does the job in one
shift. This effectively means the cutting
tool has easily paid for itself.”
Connexxioncut 4 saw blades are
available in diameters from 225 to
630mm for both stationary and flying
cut-off applications.
