Contract for three solid-state welders
SAET SpA has signed a contract for
the supply of three Emmedi MosWeld
solid-state welders to a major tube
manufacturer located inCentralAmerica.
The welders, with output power of
200, 250 and 300kW, will be designed
for the production of carbon steel tubes
according to each mill production range.
The agreement is the
result of collaboration
between the Italian sales
and technical staff together
with local and American
partners, and the company
states that it reflects
the market’s positive
response to the process
of consolidation and
expansion of the Emmedi
brand that started two years
ago by joining the Ajax
Tocco Magnethermic Corporation group
of companies.
Emmedi is taking advantage of the
new synergies with one of the oldest
and most experienced manufacturers of
induction heating equipment, to offer a
wide range of products designed to high
standards. The partnership ensures the
structure to support presence on the tube
and pipe market, widespread technical
support and after-sales services through
local offices.

A solution for high-end tube producers
DANIELI W+K (DWK) cold pilger mill 32-
Q-C for zircaloy and stainless steel tubes
and bars has successfully passed full
scale load tests at the workshop in Buttrio,
Italy, and is now under commissioning
in the Nuclear Fuel Complex plant in
Hyderabad, India. A subsequent order
signed with the same customer last
October confirmed DWK mills as a
solution to the pressing requirements of
this niche market.
The main advantages of the Quarto
mill are a rigid mill stand design capable
of resisting high separating forces; a
continuous and precise shell feeding
section with CNC machine solutions
(profiled guide ways, a recirculating
ball screw supported on both ends,
and a water cooled servomotor); and a
vibration-free mass balancing system
designed to reduce foundation works
and to minimise the overall capex of
the project.
Tooling design using 2D and 3D FEA
techniques allows simulation of the rolling
process and estimation of the separating
forces on the rolls and retaining load on
the mandrel in advance. This is a crucial
aspect for the closed loop mill design.
In the Quarto CPM configuration, load
cells can be used to monitor separating
forces on-line during production, offering
DWK the possibility to close the loop
even during operation with a proper mill
set up. The Q-Pilger approach avoids
costly trial and error, which can have a
high impact on budget and scheduling
when developing new products. In a
tough market characterised by over-
capacity, DWK states that its mission
is not only to supply new CPM mills to
customers with the necessary resources
for new investments, but also to help
tube producers use existing mills more
efficiently by installing technological
packages specifically developed to
revamp existing CPMs.

Premium threading facility in Kazakhstan
TENARIS has established a new
premium threading facility in Aktau,
Kazakhstan. The plant will support
the company’s long-term agree-
ment with Karachaganak Petroleum
Operating (KPO), plus key operator
Tengizchevroil (TCO), and will enhance
the service offer to other customers
operating in major Kazakhstan fields
with commercial, technical and logistics
expertise.
“Tenaris has been a key supplier
of OCTG in Kazakhstan, and our
Aktau plant is critical to our ability to
provide customised solutions with
sophisticated products in a region that
presents some of the most complex
drilling environments,” said Tenaris
chairman and CEO Paolo Rocca. The
facility already employs 40 people and
is scheduled to hire up to 90 direct
employees once at full capacity, with
95 per cent local jobs. The US$40mn
facility has the capacity to produce
45,000 tons of OCTG, and was
designed according to the highest
safety standards. The facility will
operate under Tenaris’s global quality,
health, safety and environment (QHSE)
policy, ISO 9001.
From this facility, Tenaris will thread
seamless pipes and gas-tight premium
connections, and it is equipped to apply
its proprietary Dopeless® technology, a
dry, multifunctional coating that offers
operational and HSE benefits.
