NASPipe elbow sections
Through the induction hardening process, we are able to
manufacture elbow sections in a wide range of sizes,
including both standard sizes (3D and 5D) and made-tomeasure products. Through this method, we are also able
to guarantee a high level of precision which is absolutely
critical for this part of the tube.
Through the versatility of the induction hardening process,
as shown below, end-users can considerably reduce
installation time and welding costs, thus guaranteeing fewer
defects on the tubes.
Other solutions
The ABRASERVICE division
of IMS S.p.A. can offer elbow
sections with a special
internal abrasion resistant
coating (60 HRC hard-facing
material).

Flanges
All our tubes can be supplied either as fixed flange or with special pipe fittings (Victaulic
or Dresser), available upon request.
Special components
It is possible to manufacture a number of special parts using our abrasion-resistant tubes:
- joints with longitudinal extensions
- Y-fittings
- Pipe fittings
- Inspection tubes
- etc…

ABRATUBE 400
tube
Applications
The main advantage of this tube is that while being highly
abrasion resistant (minimum 360 HB), they are also very
easy to install.
The tube can be welded with basic electrodes, it is easy
to work on them by attaching flanges, carrying out headto-head welding etc.

Size range
The ABRATUBE 400
seamless tube is produced
through the extrusion
process. Thanks to the
flexibility of this process, we
are able to supply to our
clients a wide range of sizes
between ø 70 and 219,1
mm, with a wall thickness
ranging from 4,5 to 60 mm.
We also supply tubes in
standard lengths, as well as
elbows and parts according
to customer specifications.
For larger diameter material than the ABRATUBE® 400 tubes,
(P)
we can offer® rolled and welded CREUSABRO 4800 or
CREUSABRO 8000 steel tubes. Elbow sections are available
(either pressed or segmented) according to the dimensions
required.
Size range
The available size range of the tubes depends on thickness,
diameter and material spcification. For more information,
please contact us.

NASPipe
tubes
NASPipe
tubes
The NASPipe tubes are
manufactured on an automatic
production line using induction
hardening technology with the
purpose of producing seamless
steel tube with good abrasion
resistant properties.
The tube is slowly heated and
then quickly cooled with water
jets, thus acquiring its ability to
resist the most severe cases of
abrasion in the field of the
pneumatic and hydraulic
transport of inert materials.
Compared to mild steel tubes,
the NASPipe tubes represent
an economical solution avoiding
the necessity of frequent
interventions on often
inaccessible installations. As
they can be up to 12 metres
long, the NASPipe tubes also
make it possible to avoid the
use of generally expensive
flanges. Their life expectancty
is 5 times longer than mild steel
tubes. The maximum operating
temperature is 160 °C.
ATTENTION
The NFA article No. 49281 of
December 1992 regulating
tubular dimensions does not
apply to NASPipe tubes or
elbows, whose dimensions are
regulated by specific criteria.

Size range
Due to the highly precise heat
treatment to which these tubes
are subjected, they can obtain
a relatively thick martensitic
structure of 600 HB up to half
of the wall thickness and a
ferritic-pearlitic structure of
about 300 HB for the rest of
the wall.

As a result, the internal wall of
NASPipe tubes has a very good
abrasion resistance, while the
outside retains a good level of
toughness and weldability. The
tubes will then present a
monolithic structure making it
easier to measure thickness
using ultrasound technology.
