stainless steel tubes
Ilta Inox, founded in 1963, produces
welded stainless steel tubes, supplying
demanding industrial sectors such as
power generation and the chemical,
pharmaceutical and food industries.
With its modern production facilities, Ilta
Inox can guarantee products that meet
stringent market requirements, and that
are certified by important international
testing organisations. The company
has been certified according to ISO
9002:1994 since 1994, and according
to ISO 9001:2000 since 2000, and is
also certified to AD 2000-Merkblatt-TRD
100 97/23/EC (PED), and has ISO 14001
environmental certification.
Raw material is purchased only from
suppliers who are ISO 9000 certified.
Before processing, the company
undertakes a 100 per cent check on
H Butting GmbH & Co KG, Germany,
is able to supply individual solutions to
customers who require duplex pipes
for urgent repairs, who have to cover
shortages of thick-walled pipes at short
notice, or who need pipes in special
sizes as quickly as possible.
Since stainless steels were first
developed, the production of high-
quality longitudinally welded pipes
has been the company’s focal point.
When longitudinally welded stainless

. The company produces
redrawn precision tubes, both in bar
and coil form, by using the TIG welding
process. The company offers a modern,
well-equipped department for tube
cutting and is able to produce cut
pieces measuring just a few millimetres
in length, completely burr-free.
incoming material using a portable
spectrometer, followed by further
laboratory analysis to verify the exact
chemical composition. A wide range of
grades and thicknesses are held in stock
to ensure that customer requirements
can be met quickly.
Slitting of coil feedstock is carried out
in-house on coils up to 30 tonnes,
followed by welding with laser welding
lines, and subsequent pickling to
remove every trace of ferrous and
oxidising contamination, which could be
detrimental to corrosion resistance. Ilta
Inox has the capability to pickle tubes in
lengths up to 18m.
Tubes produced by Ilta Inox are
subjected to a constant on-line
dimensional check (laser OD checking),
as well as continuous destructive tests,
steel pipes are required, even in small
numbers or in special sizes or materials,
Butting manufactures them from steel
plate. The company has enlarged its
stocks of the necessary pre-materials,
to ensure that they can satisfy individual
pipe requirements with short delivery
times at a high level of quality.
As well as the standard materials, 1.4541
and 1.4571, the company’s store in
Knesebeck also includes steel plates
of TP 304L and TP 316L. To cover
Tubes are produced using stainless
steels provided and guaranteed by
leading steel mills.
ISO 9001:2000 accredited (by Italcert),
the company has been certified by
RINA for its welding system and heat
treatment for the production range of
OD 6-19mm and wall thickness of 0.4
to 1.1mm.

including flaring, flattening, reverse
bending and expansion, in order to
evaluate the integrity of the weld area.
In addition, in order to guarantee the
integrity of the whole tube wall, 100
per cent of production is eddy current
tested off-line.
The Ilta Inox production programme
includes round tubes in a wide range
of austenitic stainless steel grades
including 304, 304L, 321, 316, 316L,
316Ti, 316SL, 310S, 31803, and 309.
The company has recently extended
the size range of its production to
include tubes up to 711mm OD, with
annealed tubes now available up to
219.1mm OD.

company can produce pipes with wall
thicknesses from 6.35 to 12.7mm. The
company also specialises in storing steel
plate in duplex or super duplex. Butting
can manufacture, within a very short
time, duplex pipes (UNS 31803 or UNS
32205) in wall thicknesses from 4.78 to
22.7mm.
