Seam normalizing A guide to the benefits of induction heating

Advanced seam normalizing. For advanced alloys and pipe. In-line seam normalizing systems from EFD Induction—a proven way to meet oil and gas pipe standards. Normalizing the weld zone on longitudinally welded pipe is technically challenging. And it is becoming ever more so, due to the new generation of high yield strength thermo mechanically processed steels and gauges being used in the oil and gas industries. These new materials and dimensions typically have narrower tolerances, meaning the normalizing process must be extraordinarily accurate, reliable and controllable. There are other...

Your entrance ticket to the oil and gas pipe market. EFD Induction is a leader in modern, cost-cutting seam normalizing. Our solutions (which feature both NQN and NQT installations) can be found around the world, working for demanding pipe manufacturers to ensure that: • The temperature at the inner wall is sufficient to achieve full homogenization. • The heat pattern at the inner wall is wide enough to cover the full Heat Affected Zone. • The temperature at the outer wall is kept to the minimum required for homogenization, thus avoiding the risk of coarse grain re-growth. pendently, and...

High uptime. High throughput. High quality. A complete EFD Induction seam normalizing system typically includes: a Sinac converter, workstations with induction coils, a flexible power cable, and a control system. All our seam normalizing systems include a ‘quick lift’ device to prevent open seams or deformed pipes from damaging the coils. An EFD Induction Sinac converter (left) and a seam normalizing workstation. Sophisticated software and numerous sensors make the process control solution in such systems the most advanced on the market. EFD Induction is Europe’s no. 1—and the world’s no....
