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)

• 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
