High gloss
tube polishing
and finishing
RC200 is a new
centreless tube polishing
and abrasive belt
grinding machine that
combines finishing,
satining, buffing and
mirror polishing in
straight tubes in a single
piece of equipment.
The quick change
of contact roller for
polishing wheel and
the flexibility of design
of RC200 in order to
work under wet and dry
conditions makes it easy
to perform wet belt grinding and tube gloss polishing in dry
operation.
The centreless system enables the finishing and
polishing of short components from approximately 100mm
up to long tubes. Adjustable in feed and out feed roller
tables can be supplied in order to support and store tubes
with high lengths or heavy pipes. Its modular construction
makes it possible to join several tables and meet the total
length required by each production range.
The wet cooling system, used for tube abrasive belt
grinding, where the water is flowing and cooling down the
tubes, runs on a closed circuit. Dusty water is decanted
and, once cleaned, is pumped back to the finishing point,
allowing an efficient consumption of liquid. In addition, a
water level shows the operator the exact quantity of water
available.
A 3m long abrasive belt with 100mm contact area,
combined with a flood of coolant and the strength of the
regulating roller, permits heavy material removal in pipe
grinding and quality belt finishing in tubes. The abrasive
belt easy tensioning system, proved and tested in all NS
FG machines, makes abrasive belt replacement a quick
and practical operation made within a few seconds without
the need of any tools.
RC200 features a strong construction of the regulating
head with adjustable pressure and bi-directional feeding
direction. Having these two feeding directions feature
decreases handling costs, especially when tube mirror
polishing is required, enabling multiple passes on the
polishing buffs without having to remove the tube from
the work rest and feeding roller tables. Different work
rest supports equip the machine, enabling grinding and
polishing of tubes from 10 to 206mm OD.

Putting the smarter heat to smarter use
This is not a pipe.
It’s actually an entry ticket to huge markets. Because what
you’re looking at is a longitudinally welded pipe that’s been
normalized to oil and gas pipe standards. But there’s a catch.
Normalizing isn’t easy. Especially for today’s gauges and alloys.
It demands expertise in metallurgy, control software and precise
heat delivery.
The good news however is that these are areas in which we
specialize—making us a leader in pipe weld-seam normalizing.
Also, with more than 50 years’ induction heating experience,
we’re experts at using technology to open new commercial op-
portunities for our customers.
EFD Induction is Europe’s no 1—and the world’s no. 2—
induction company. Our systems are used to weld, normalize,
anneal, harden, temper, braze, melt, forge, bond, cure and pre-
and post-heat.
So whatever your pipe normalizing needs, you can turn to us
for a solution. And since we’re present around the world, that
solution is probably closer than you think. Contact us today.
There’s a vast oil and gas pipe market out there. We’ll help you
get a share of it.
