“The new line will produce premium connections used by oil and gas companies in the most challenging environments, such as offshore, deep water, corrosive, high temperature and high pressure wells,” TenarisSilcotub said in a statement.

The new pipe finishing line has total processing capacity of 35,000 tons a year.

TenarisSilcotub, a unit of Luxembourg-registered group Tenaris, invested over $300 million in Romania since 2005.

Last year, the company has completed a $60 million investment in a production unit in Zalau, with a total capacity of 75,000 tons a year.

Apart from the steel pipe plant in Zalau, Tenaris operates two other units in Romania, namely a steelworks in Calarasi and a service center in Ploiesti.
