Tube Russia – 28-31 May, 2007 ›››
Maschinenfabrik Liezen und Gießerei
(MFL) is a manufacturer of sawing and
milling machines, supplying producers of
precision and seamless pipes worldwide.
These plants are designed for the sawing
of stainless steel, iron and aluminium in the
form of solid materials, pipe, extrusions and
plate.
These custom-made solutions are used for
specific applications such as tube or profile
layers, billets or plate sawing plants. Each of
MFL’s machines is designed to use carbide
tipped saw blades, which guarantee high
capacity, low costs and a long service life.
At Tube Russia, MFL will present the
sawing machine, branded HK 550 E30,
which has 30kW of driving power. This
machine is designed for cutting round
workpieces and tube with a diameter from
30-160mm and squared workpieces with a
maximum dimension of 145mm in a single
cut operation. The sawing machine can
be equipped with a maximum saw blade
diameter of 550mm.
MFL also supplies the HK 2200 E160 type
of sawing machine for workpiece diameters
up to 800mm. In addition, MFL supplies
edge milling machines for the edge
preparation of welded tubes. The movable
milling head holds the latest state-of-the-
art carbide tips. Using this machinery, a
precise and smooth surface is achievable
in spite of high milling parameters and short
cycle times.
MFL is an experienced supplier of the
chip removal process and delivers turnkey
plants as well as single machines for the
modernisation or increased performance of
tube production.

Linsinger Maschinenbau, Austria, is the
manufacturer of an advanced range of
sawing and milling machines.
The company supply equipment for large
pipe that includes plate edge milling
machines for welding edge preparation,
and pipe bevelling machines for bevelling
both ends simultaneously on pipe up to Ø
60".
For spiral pipe, the company supplies strip
edge milling machines for spiral steel tube
lines using coil up to 2,000mm width and 1"
sheet thickness.
For ERW-lines, Linsinger manufactures
strip edge milling machines for longitudinal
seam tubes (HF-lines up to 24"), and
multi-cut tube cut-off machines for
longitudinal edge tube lines (up to
Ø 600mm tube).
In the area of seamless pipes, Linsinger
Maschinenbau offers carbide circular
sawing lines for steel billets and single
tubes (up to Ø 630mm), and multiple
tube layers (up to 1,250mm width). The
company also produces carbide circular
saw blades for forging mills (steel billets up
to Ø 630mm).
Linsinger produces the necessary carbide
saw blades and miller only for Linsinger
machines. In Europe, the company also
offers a full re-sharpening and repair
service.

Magnetic Analysis Corporation (MAC),
USA, manufactures non-destructive test
equipment and systems to inspect tube and
bar.
The company's latest Echomac® FD-4
ultrasonic inspection instrumentation will
be featured on the company’s stand at
Tube Russia, alongside encircling coil eddy
current testers such as the MAC 175 or
MAC 400.
Information will also be available on
the latest Rotoflux® flux leakage system
recently delivered to a customer in
Kazakhstan.
The FD-4, the latest in MAC’s Echomac
line of ultrasonic test instrumentation
and control electronics, is a significantly
enhanced product designed for flaw
detection, and measurement of wall
thickness and outside diameter in tube and
pipe applications. It is suited for use in both
new installations and retrofit applications
using existing transducers.
The FD-4 features 32 test channels in a
single system, and operates on a Windows
XP platform.
With the new OD measurement capability,
the FD-4 can report OD and ID dimensions
and ovality, in addition to wall thickness,
eccentricity, and wall variation. The
equipment also includes full network
support.
The 16" capacity Rotoflux includes multiplex
electronics consisting of 24 channels from
24 separate test probes.
The new test screen display simultaneously
shows all OD and ID channels, while a strip
chart display shows the maximum ID and
OD signals from any of the 24 channels.
Thresholds for ID and OD can be set
independently, and each channel can be
viewed separately onscreen with zoom-
in capability. The heavy-duty mechanics
include a built-in calibration station, parallel
to the test line, with its own pinch stands
and conveyor.
The slide and elevate platform allows the
rotary test head to be easily moved away
from the test line for calibration tests or
maintenance, and a jib crane can be
incorporated for handling the calibration
standard.
