Induction technology
for pipe end heating
INDUCTOTHERM Heating & Welding
has supplied its range of IROSS
Fluxmanager equipment to a number
of pipe manufacturers within the OCTG
sector. The IROSS Fluxmanager is
designed for use in an array of pipe
end heating applications for a variety
of tubular goods, including drill pipe,
casing, and API pipe.
Suited to the OCTG sector, the IROSS
Fluxmanager system is specifically
designed for use in applications such
as preheat for welding, preheat for
swaging, hardening, annealing, removal
of cure and coatings, and friction weld
and stress relieving.
The patented Fluxmanager unit uses
an efficient 50/60Hz low frequency
system that provides deep, uniform
temperature distribution, ID/OD, both
laterally and longitudinally along
extended lengths of pipe ends. The
pipe end exits the coil immediately with
a repeatable temperature uniformity
of ±25°C (77°F), and no soak time is
required.
Inductotherm states that the IROSS
Fluxmanager system has become
recognised and adopted into the OCTG
sector as standard equipment and
when compared with traditional medium
frequency pipe end heating techniques,
the IROSS Fluxmanager allows for
greater control of end heating, with a
shaped intensifier to concentrate power
on the workpiece.
The
system
heats within tight
specifications at a
reduced cycle time
and easily adapts to
OD variation.
Only
four
coil
sizes are required
to cover the entire
range of OCTG pipe
diameters. The shaped flux
concentrator allows for completely
repeatable results even when the pipe
is placed non-concentrically in the coil
itself.
Infrared, thermal imaging and intuitive
data logging functionality can be
specified by the customer in order to
satisfy the stringent quality requirements
within the OCTG market.

Intelligent pipe mills
FD Machinery Co has introduced a new
pipe mill that has advantages in roller
changing.
With the FDM-X2 Auto DNSA
intelligent pipe mill, the following steps
are required for changeover operations.
Firstly, the product size is entered – three
or four numbers. Then auto-change of
the horizontal and vertical rolls is carried
out (auto-change of vertical rolls is
optional). FDM-X2 DNSA contains
both auto and manual changeover
devices. This design can guarantee
output if one device is shut down.
Only one wrench is needed for
manual change.
Auto-changeover
takes
30
minutes with one operator. Manual
changeover takes
60 minutes with two
operators. The auto-
changeover
and
adjust device is not
only suitable for the
new mill, but is also
applicable to existing
mills.
FD Machinery has
also launched the
FDM-X Auto CFS
intelligent square pipe
mill, which changes
size without changing rolls. Only two
steps are necessary to complete a size
change: enter the product size (four
numbers), then auto-change size and
adjust pass.
No roller is changed. Only one
operator is required, and the process
takes ten minutes.
