EVRAZ North America orders TemperLine heat treatment system

EVRAZ North America, based in Chicago, has placed an order for an Elotherm TemperLine heat treatment system for its tubular products plant in Calgary (Alberta/Canada). With this unit EVRAZ is increasing its capacity for heat-treated pipe by over 150 per cent.

The Elotherm TemperLine in operation is designed for the heat treatment of up to 30 tonnes of OCTG (Oil Country Tubular Goods) per hour.  Due to the high flexibility of Elotherm’s technology, with negligible down-times for changing pipe size or final grade, this 12 MW- TemperLine is capable of an overall yearly throughput of more than 200,000 metric tons per year of heat treated pipes.

"The Calgary expansions will allow us to offer a more comprehensive product portfolio to meet growing needs for premium OCTG products," said Tigran Atayan, Executive Vice President–Tubular Products Group for EVRAZ North America. "This project, as well as the premium threading line expansion already underway at our Red Deer facility, demonstrates our strong commitment to customers in Western Canada."

“In order to obtain the best metallurgical, mechanical and geometrical results on the processed pipes, the Hardening unit is split up into seven different zones, each fully independently powered and controlled” says Dr. Guido Opezzo from Elotherm in Germany.  “This renders it possible to finely adjust the power injected into the pipes and use the final zones as standard final heating zones for ERW pipes or Soaking areas, when processing seamless pipes and high qualified grades” says Opezzo.

EVRAZ tubular facilities manufacture a wide range of OCTG, including carbon and alloy products and premium connections, as well as small and large diameter line pipe, all of which meet or exceed standards set by the American Petroleum Institute (API).

The induction heating unit is scheduled to go into operation in the 4th quarter of 2014.
