1. Longitudinal Welded Process Steel sheet formatted to pipeCoil 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

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

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

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

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) 1. Number of turns 2. Coil Lenght 3. Internal Diameter 4.Coil Tubing Diameter 5.Left or Right Turn 6.Lenght of the ends 1 6 3 2 4 5

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

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 a hole - PLH Round with Slot - PLS Round with a hole and slots - PLSH PLSHS
