Description
What Are Scarfed Tubes?
Scarfed tubes are welded tubes where the internal weld bead has been removed after welding.
Compared with non-scarfed tubes, scarfed tubes offer:
- Smoother internal surfaces
- Reduced cutting impact
- Better dimensional consistency
- Improved cutting stability
This allows flying cut-off saw blades to achieve higher cutting speeds and superior cut quality.
