EVRAZ North America ordered an Elotherm TemperLine™ heat-treatment system for its tubular-products plant in Calgary, Alberta. With this unit, EVRAZ is increasing its capacity for heat-treated pipe by over 150%. This TemperLine will be designed for the heat treatment of up to 30 tons of OCTG (oil-country tubular goods) per hour. The 12-MW system, which is scheduled to go into operation in the fourth quarter of 2014, will be capable of heat treating more than 200,000 tons of pipes per year.
In order to obtain the best metallurgical, mechanical and geometrical results on the processed pipes, the hardening unit is subdivided into seven different zones. Each zone is fully independently powered and controlled, rendering it possible to adjust the power input into the pipes and use the final zones as standard final heating zones for ERW pipes or as soaking zones when processing seamless pipes and premium grades.
