Longitudinal Welded Process
Steel sheet formatted to pipe Coil
The impeder or ferrite goesInside the pipe
The coil induces a current inThe outer side of the seam Tube
The impeder or ferrite intesifyThe energy the current ADCWich increase the heating

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

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

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

• 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 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
