  1. Longitudinal Welded Process The impeder or ferrite goes Inside the pipe The coil induces a current in The outer side of the seam Tube The impeder or ferrite intesify The energy the current ADC Wich increase the heating Steel sheet formatted to pipe Coil

  2. Longitudinal Welded Process The Impeder / Ferrite goes inside The pipe Tube Welding Cooling oil Coil Tube Pipe Direction of Travel

  3. Typical Steel Pipe Generator system High frequency cable RF Box detail Power tube Power Tube Control Panel RF Box Welding Head Coil Water cooling system Power Supply Cabinet

  4. Typical Steel Pipe Generator system Coil High freq Coax cable RF Box Welding Head Capacitor bank Resistor Bank

  5. Steel Pipe • Longitudinal Welded Steel Pipe use high frequency generators with: • Power Tube Technology • Solid State Technology • Main Brand Machines • Thermatool • Tocco • American Ind • Inductron • Emmedi • What we can sell in both Generators: • Power Tube (E2V + Penta) • Transistors (to be defined) • Capacitors (Ceramic water cooled + Vacuum Capacitors) • Coils • Impeder

  6. Steel Pipe • Power Tube • Most part of the tubes are High Power and Water Cooled • Penta main Products • 3CW45000H3 • 6696A • 7560 • E2V main Products (only to Latin America) • BW1184J2 • BW1185J2 • BW3300J2

  7. Steel Pipe • Capacitors • Water Cooled Ceramic Capacitors (PLWCC products line) • Vacuum Capacitor (only high power equipments) • Induction Coils and Impeders • Star Tecnologia Partnership (Brazil) • Coil (follow the questionaire) • Number of turns • Coil Lenght • Internal Diameter • Coil Tubing Diameter • Left or Right Turn • Lenght of the ends 1 2 3 5 6 4

  8. Steel Pipe • Impeders • Usually customer has the p/n of what they use • Though Flow – most popular • Exposed Through Flow – increasing process speed • Return Flow – dry process • Hollow Return Flow – allow cutting heads + internal painting 1 4 1 2 3

  9. Steel Pipe Market Training • Casings • Magnetic (Ferroglass) - glass impregnated with ferrite powder, increase the size of the impeder • Epoxy Glass - least cost, highest wear resistance • Silicon Glass – highest temperature resistance, waterproof, used for return flow impeders • Ferrites • Sintered oxides of iron, cobalt, manganese, nickel and zinc • Different Shapes for different applications Round - PL Round with Slot - PLS PLSHS Round with a hole and slots - PLSH Round with a hole - PLH
