Iranian contract for latest vacuum
tube welder technology
Profile Saman Sepahan, Iran, has signed a contract for 8 new Emmedi vacuum tube
welders, which offer output power of 200kW and 350kW. The welders are designed to
manufacture carbon steel water and gas tubes.
Emmedi, part of the Saet Group, has a range that includes high frequency inline
induction welders for metal pipes, medium and high frequency equipment for
heat-treatment, inline bright annealing equipment, and seam/full body annealing
systems.
The merging of Emmedi into the Saet Group has given the company the possibility to
improve technological innovation and research. Emmedi has developed new products
such as its solid-state welder, recently presented at Tube 2008 in Düsseldorf.
The company has sold 40 pieces of equipment worldwide in the last two years. The
company’s ‘Classic’ range of vacuum tube welders is available with between 50kW and
1,200kW output power.

Tenova win major
Brazilian furnace contract
Vallourec & Sumitomo Tubos do Brasil
Ltda, a joint venture formed in mid-2007 by
France’s Vallourec and Japan’s Sumitomo,
has chosen Tenova Melt Shops to supply
a greenfield plant in Brazil comprising
Consteel®, an electric arc furnace and a
dedusting system.
The facility will be installed at the new
seamless steel tube production centre to
be built in Jeceaba, in the region of Minas
Gerais, an area with some of the world’s
richest iron-ore reserves.
The 140t electric arc furnace, fitted with the
Consteel® system, will turn out more than 1
million tons of liquid steel a year. Production
is expected to begin in 2010.
“This is the first Consteel installation in
South America,” says Mr Raimondo di
Carpegna Varini, senior vice president of
Tenova SpA, “Moreover the agreement
was drawn up in just nine months,
a record time for a project of this
scale.”
The plant is claimed to be the first in the
world to use an innovative metal feed mix
for an electric steel mill. Mr Francesco
Memoli, Tenova’s area manager for
North and South America, explains
“The furnace can be charged with up to
80 per cent of solid and liquid pig iron,
including more than 50 per cent of hot
metal. This combination will guarantee
high productivity and cut costs, while
the Consteel® technology will reduce
environmental impact.”
The project confirms Consteel as leading
technology in the market for high-quality
plants. It also provides Tenova with a major
reference in an area offering some of the
richest reserves of raw materials for steel
production.
