When producing welded pipes according to API specification or similar, the weld and the heat affected zone (HAZ) have to be normalized. EFD Induction has three solutions.
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 seam normalizing systems available from EFD Induction include horizontal tracking, orbital tracking and travelling systems.
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.
EFD Induction seam normalizing systems are easy to control and specially designed to work with EFD Induction power sources, coils and handling mechanisms. Each control system can handle up to four induction heaters independently, and features temperature control of the seam heating as well as seam tracking control of the induction coils in manual and automatic mode. A recording unit records and stores important process parameters for all treated seams.
