Producers of API grade oil and gas
pipe may also be interested to discuss
Thermatool’s new Smart Annealing system,
which when used in conjunction with orbital
seam tracking has been designed to provide
the operator with a greater level of process
control.
Inductotherm is also a supplier of
Radyne induction heating systems for
pipe pre-heating prior to the application of
protective coating. Radyne has considerable
experience with multi-layered PE and FBE
coating applications on pipes up to 120" in
diameter.
With over 1,400 solid-state HF welders
in operation worldwide, Thermatool has a
welder for every application. At Tube Russia
the company will introduce its new compact
single cabinet welder, suitable for tube
producers who only need to weld a limited
product range. This new welder offers high
electrical efficiency at an affordable price,
making it an option when replacing older
thermionic valve units.

GEBRÜDER Lennartz GmbH & Co KG
manufactures and supplies carbide-tipped
circular saw blades for the ferrous and non-
ferrous industry.
The company has introduced a new
development in saw blade technology.
The X-max blade is a circular tipped saw
blade designed for cutting special and high
alloy steel produced by the seamless tube,
forging, aircraft and automotive industries.
Due to continuous enquiries for circular
saw blades for cutting high chromium
steel with more than 10% chrome, nickel
base alloys, stainless steel, duplex and
super duplex, Lennartz decided to offer
a suitable cutting tool to meet customers’
requirements. Previously, it was almost
impossible to cut these materials
economically with carbide-tipped saw
blades because of the very low wear life in
relation to the cost of the blade.
The company states that successful trials
together with targeted customers, users
and machine manufacturers have shown
that the X-max blade is able to achieve life
times which are five to seven times higher
than conventional circular saw blades.
Cutting the X20Cr13 grade, the X-max
reached a material removal of nearly 16m2.
Conventional blades reach a material
removal of 3m2 maximum. The same results
were proven when cutting P91/T91. The
achieved wear life is 9 to 13m2, compared
to 3 to 5m2.
Alloys that were nearly impossible to cut
with any saw blade, are now said to be easy
work for the X-max blade. With the X-max
blade, one customer achieved a material
removal of more than 7m2 when cutting
super duplex material.
Further wear life tests and enhancements
are planned to further improve the blades’
performance. Lennartz claims that using
the X-max blade is an advantage for any
application with difficult alloys or steel
grades, and that this applies for cutting
tubes (single or layer) as well as for cutting
billets.

THE CNC handheld marking system MV5
M75 has been equipped with a new space-
saving controller, MV5 ZE 301 XL, as part of
Markator’s XL product development project.
The controller’s features include a high-
resolution LC colour display and three USB
interfaces. These new interfaces enable the
use of a PC keyboard, a barcode scanner
or a USB memory stick.
The transfer of marking files from an
external PC or the administration of logo
files can be performed easily. Software
update is possible via USB. Hundreds of
marking files or logos can be saved directly
on the controller, and an external hard disk
is unnecessary.
The device is a compact, electro-
pneumatically operated marking system for
efficient, permanent and quick markings for
all kind of metal parts (even hardened steel,
up to maximum 62 HRC), plastics, wood,
glass, etc, with variable texts. It can also
mark finished products that are sensitive to
pressure, thin walled, laminated or round.
The system is specially developed for
marking on heavy and unmovable parts
directly on location.

Maschinenfabrik Liezen
und Gießerei GmbH
Austria
Maschinenfabrik Liezen und Gießerei
GmbH (MFL), Austria provides customised
sawing and milling equipment for tube
manufacturers all over the world.
The product range includes: plate edge
milling machines for ERW pipes; strip edge
milling machines for longitudinal welded
pipes; circular layer sawing machines for
seamless pipes and profiles; circular single
cut sawing machines for tubes, billets,
ingots and profiles; and welding seam
processing machines and pipe bevelling
machines.
The unique welding seam processing
machine removes the overlaying inner and
outer welding seam of large-diameter pipes
over a length of 400mm. This process offers
a number of advantages compared to the
common, manual grinding process.
