Induction technology for pipe end heating

recognised and adopted into the OCTG sector as standard equipment and when compared with traditional medium frequency pipe end heating techniques, the IROSS Fluxmanager allows for greater control of end heating, with a shaped intensifier to concentrate power on the workpiece. The system

INDUCTOTHERM Heating & Welding has supplied its range of IROSS Fluxmanager equipment to a number of pipe manufacturers within the OCTG sector. The IROSS Fluxmanager is designed for use in an array of pipe end heating applications for a variety of tubular goods, including drill pipe, casing, and API pipe. Suited to the OCTG sector, the IROSS Fluxmanager system is specifically designed for use in applications such as preheat for welding, preheat for swaging, hardening, annealing, removal of cure and coatings, and friction weld and stress relieving. The patented Fluxmanager unit uses an efficient 50/60Hz low frequency system that provides deep, uniform temperature distribution, ID/OD, both laterally and longitudinally along extended lengths of pipe ends. The pipe end exits the coil immediately with a repeatable temperature uniformity of ±25°C (77°F), and no soak time is required. Inductotherm states that the IROSS Fluxmanager system has become

heats within tight specifications at a reduced cycle time and easily adapts to OD variation. Only four coil

sizes are required to cover the entire range of OCTG pipe diameters. The shaped flux concentrator allows for completely repeatable results even when the pipe is placed non-concentrically in the coil itself. Infrared, thermal imaging and intuitive data logging functionality can be specified by the customer in order to satisfy the stringent quality requirements within the OCTG market.
