Description
What Is Non-Scarfed ID Cutting?
In many ERW tube mills, the internal weld bead is intentionally left unremoved (non-scarfed).
Compared with scarfed tubes, non-scarfed tubes present additional cutting challenges:
- Hard weld zones
- Higher impact loads
- Increased blade wear
- Greater heat generation
Our specialized flying cut-off blades are designed to withstand these demanding conditions while maintaining clean and accurate cuts.

Frequently Asked Questions
What is the difference between scarfed and non-scarfed ID pipes?
Non-scarfed pipes retain the internal weld bead, requiring more durable blade designs capable of handling higher cutting loads.
Can these blades cut API grade pipes?
Yes. They are specifically designed for high-tensile-strength API pipe applications.
Are custom tooth geometries available?
Yes. We optimize tooth design according to your tube size, wall thickness, and production conditions.
Do you provide PVD-coated blades?
Yes.
