intensifier greatly improves electrical efficiency and power factor compared to open coils. With the necessity of processing pipes of different diameters and walls and the specifics of the real-life industrial environment, it is not uncommon to have a non-symmetrical positioning of the heated pipe inside the induction coil. Fluxmanager™ was designed to compensate for the off centred aligned pipe making no difference to the heating and final exiting temperature. By including programmable frequency this allows even greater control of the HAZ and no overheating of the skin, reducing the normal high peaks of temperature during initial start-up of the heating. Advantages are achieved using Fluxmanager™ technology by addres- sing the following areas: improved equipment flexibility, repeatability and changeovers and service, energy savings and noise reduction. Manchester Tool & Die supplies tube end-forming equipment and tooling to a variety of industries, with standard machines ranging from 3 / 16 " to 3" OD capacities. Machines and parts can be manufactured for special applications. The company also provides steel fabricating and production machining services.

MANCHESTER Tool & Die, Inc (MTD) is exhibiting at Fabtech 2016 (Booth N7108), 16-18 November at the Las Vegas Convention Center in Las Vegas, USA. On display will be MTD’s Model M71-E-6 electric tube end forming system for tubes up to 1½" in diameter. This machine is claimed to offer up to a 40 per cent faster cycle rate than comparable hydraulic machines. A servo flag stop system is standard for these machines for quick, tool-free flag adjustments, which helps achieve quicker and more accurate set-ups. The electric tube end-forming machines also provide easy access for tooling

Precision pipe end heating THE ability to provide uniform heating with a flexible and robust induction stress relieving unit that offers the highest quality has always been the key benchmark for the Inductotherm Group. The Inductotherm stress relieving unit called Iross offers customers precise heating of the heat affected zone (HAZ) exiting the coil, giving no need for extended soak time in order to reach the temperature tolerance required. This is achieved by using a patented system called Fluxmanager™, developed by the Inductotherm Group to improve shortcomings of using conventional stress relieving systems.

robustness with reduced sensitivity to real life plant process disturbances and imperfections; elimination of the use of “robber” rings; ensuring superior radial, circumferential and longitudinal temperature uniformity; and reduction of an external magnetic field around the induction coil. The Iross stress relieving machine is available in two formats, single phase and three phase, both designed specifically for heating a wide variety of tubular products while delivering the industries best heat affected zone according to Inductotherm. Both systems also utilise recipe- driven programming, which inc- orporates a PID control to manage the heating curve and the soaking time if required. These systems utilise patented Fluxmanager™ technology yielding superior temperature uniformity compared to conventional designs. The three phase heating system features programmable variable fre- quency control, allowing precise heating on a variety of pipe sizes and wall thicknesses.

FluxManager™ utilises a shaped intensifier to concentrate power on the workpiece. The Fluxmanager™ coil is a closed end coil giving a superior control of heating at the cold end, preventing under heating and cold spots. The
