Seam Annealing
Thermatool Seam Annealers
Thermatool’s globally proven Seam Annealing equipment is engineered to deliver highly effective Post Weld Heat Treatment (PWHT) across a wide range of tube and pipe diameters and materials.:
- SmartAnneal™ Control: Ensures repeatable quality control through closed-loop temperature control and real-time monitoring.
- Focused Inductor Design: Features a "V" shaped inductor that concentrates magnetic fields onto the HAZ, maximizing efficiency and preventing surrounding overheating.
- Speed Power Control (SPC): Automatically adjusts output power based on mill speed to maximize yield and eliminate scrap.
- Proven VIP® Power Supplies: Backed by over 30,000 installations worldwide, maintaining a constant high-power factor with minimum distortion.
Thermatool® Seam Annealers offer an advanced automation package with recipe recall, perfectly adapting to standard, spiral, structural, and custom tubular profiles.
Features
- Greater than 92% efficiency/0.95 input power factor for all conditions.
- Mill-mounted carriage assembly for precise positioning of the inductor.
- Optional horizontal slide track available.
- Quick-lift mechanism to rapidly raise the inductor from the pipe, away from any open seam conditions.
- Automated seam-tracking capability option.
- Independent free-moving carriages for simple offline maintenance.
- Single and dual inductor configurations available to meet a wide variety of applications.
- Proprietary “V” inductor geometry for increased efficiency and focused heating.
- Real time feedback via PLC control.
