IMATEK has installed a 30,000J DWT40-
30, drop weight tear tester (DWTT) at Ural
Steel in Novotroitsk, Russia.
The DWT40-30 replaces an older
machine and will be used to test the fracture
properties of steel used in the manufacture
of large diameter pipe for the oil and gas
industries.
This is a significant installation for Imatek
as it represents the company’s first sale
into Russia following the appointment of
new distributor, Uralsibpromservice (USPS)
based in Chelyabinsk.
Ural Steel is a subsidiary of the holding
company Metalloinvest and is the largest
enterprise in the South Ural region and one
of the eight leading metallurgical integrated
works in Russia. The company was founded
in 1955. Today, Ural Steel is a significant
niche steel producer, holding the top market
position in production of strips, tube billets,
bridge steel, machinery construction steel
and billets for exports.
The products of Ural Steel are highly
demanded in Russia and the CIS as well
as on the international markets. Customers
include leading enterprises from such
countries as Russia, Germany, UK, Italy,
Spain, Belgium, Norway, Denmark, Turkey,
Iran, China, Korea, Vietnam, Taiwan and
Thailand.
The use of higher grade steels in the
oil, gas and manufacturing industries is
creating the need for a new generation of
specialist impact testers. Imatek offers a
range of DWTT systems for measuring the
fracture characteristics of steel specimens
according to API recommended practice
5L3, EN 10274 and ASTM-E 436. Steel
grades of X120 and specimens of up to
50mm can be accommodated.
A major feature of the Imatek range is the
high-quality instrumentation and analysis
software that provides detailed information,
both graphical and tabular, for the specimen
failure.
Whereas historically the DWTT test
method has not required instrumentation,
more recent research indicates that it is of
significant benefit when testing the tougher
X-steels.
Instrumentation enables crack initiation,
and most importantly crack propagation
energies, for the specimen to be determined
which is considered a better measure of
‘in-use’ performance for these steels than
visual assessment of the fracture surface.
