Argentine steel tube and equipment producer Siat has won a tender to supply pipes to state energy company Enarsa, the former's 30% owner TenarisConfab said in a filing to São Paulo's Bovespa stock exchange.
Siat is due to provide 1,182km of pipes to Enarsa under the contract worth US$549mn, before taxes.
São Paulo-based TenarisConfab will provide another 327km of welded steel tubes in the deal worth US$178mn before taxes, according to the filing.
Deliveries are expected to start within 21 months of the date the contract is signed.
Both pipes will be used for the GNEA natural gas pipeline, according to the filing.
