Description
What Are Non-Scarfed Tubes?
In many ERW tube mills, the internal weld bead is intentionally retained after welding rather than removed through the scarfing process.
Compared with scarfed tubes, non-scarfed tubes present more demanding cutting conditions due to the remaining internal weld bead. These conditions require flying cut-off saw blades with higher impact resistance, greater wear resistance, and optimized tooth geometries.
Typical cutting challenges include:
- Hard internal weld bead
- Higher impact loads
- Increased blade wear
- Greater heat generation during cutting
Our TCT Flying Cut-Off Saw Blades are specifically engineered to withstand these demanding conditions while delivering clean, accurate, and stable cutting performance.

Frequently Asked Questions
What is the difference between scarfed and non-scarfed tubes?
Non-scarfed tubes retain the internal weld bead after welding, resulting in higher cutting loads and greater blade wear. Therefore, they require stronger carbide grades and optimized tooth geometries to ensure stable cutting performance and longer blade life.
Are these blades suitable for cutting API-grade pipes?
Yes. Our TCT Flying Cut-Off Saw Blades are specifically designed for high-strength API pipe production and other heavy-duty tube cutting applications.
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 PVD-coated blades available?
Yes. PVD-coated versions are available to provide improved wear resistance, higher heat resistance, and longer service life under demanding cutting conditions.
