Doosan Heavy Industries & Construction qualifies Tenaris mill in Romania

Production automation, a corporate quality system and a dedicated team were
the key factors leading to the qualification of Tenaris's Silcotub mill in Zalau,
Romania as a tubing supplier for Korean Doosan Heavy Industries &
Construction's boiler and HRSG needs.

On September 24, representatives from the quality control, Non Destructive
Testing (NDT) and purchasing teams of Korean Doosan Heavy Industries &
Construction (DHIC) visited the hot rolling mill, the new finishing line, and
laboratory in order to qualify the mill as a supplier of tubes for boilers and
HRSG.

"I gladly inform you that Silcotub was evaluated as a Qualified Manufacturer for
boiler and HRSG tubes. NDT was excellent and we had no choice but to qualify
Silcotub without any doubts," announced Mr Hyunyong Park, DHI Purchasing
Manager, on October 16.

During the visit DHIC was impressed with the dedication of the team and the
quality control system. In the rolling mill, the automation was particularly
appreciated while in the non-destructive testing line, the skills of the people,
the inspection process, the operative practices and procedures to control
defects were object of thorough analysis. The new, state-of-the-art finishing
line was also visited and the procedures to handle 26-meter long tubes for
HRSG needs and to ensure consistent product quality were explained.

HSE compliance and reduced lead-times to reach key projects in the Saudi
Arabian power generation market were other factors that contributed to the
qualification.

Prior to the Romanian mill's qualification, DHIC has been buying from Tenaris's
facilities in Italy a range of different products: from hot rolled - both MPM and
transversal- to cold drawn in small, medium and expander diameter tubes in
low- and medium-alloy steels for gas cycle and coal fired power plants.

Since 2011, Tenaris has been supplying tubes for Doosan's power generation
projects in Vietnam, Saudi Arabia and India.
