impedors larger diametersImpedors are an integral and critical component in the pipe welding process. Often neglected, they can cost your business thousands of Euros every year if they are not properly designed, manufactured and selected correctly. At STE we ensure that our impedors have the highest quality ferrite grade to give optimum efficiency and stability during the production process. We protect these ferrites with the best available casings thus ensuring effective cooling, resistance to mechanical damage and good thermal endurance.
