Description
What Are Scarfed Tubes?
Scarfed tubes are Electric Resistance Welded (ERW) tubes with the internal weld bead removed after welding. The scarfing process produces a smoother inner surface and improves dimensional consistency, making the tubes easier to cut at high production speeds.
Compared with non-scarfed tubes, scarfed tubes offer:
- Smoother internal surface
- Reduced cutting impact
- Better dimensional consistency
- Improved cutting stability
- Higher cutting speeds
- Superior cut quality
These advantages enable flying cut-off saw blades to deliver cleaner cuts, longer tool life, and greater production efficiency.

Frequently Asked Questions
What is the difference between scarfed and non-scarfed tubes?
Scarfed tubes have the internal weld bead removed after welding, resulting in smoother cutting conditions, improved dimensional consistency, higher cutting speeds, and better cut quality than non-scarfed tubes.
What production speeds are recommended?
Our TCT flying cut-off saw blades are recommended for production line speeds ranging from 200 to 600 m/min, depending on the tube material, wall thickness, and machine conditions.
Can you customize the tooth geometry?
Yes. We optimize tooth geometry based on tube diameter, wall thickness, material grade, production speed, and machine specifications.
Are coated blades available?
Yes. We offer advanced PVD-coated versions for improved wear resistance, heat resistance, and extended tool life in high-speed cutting applications.
