In a modern pipe production line, the Friction Saw (Flying Saw) is a key piece of equipment used for continuous, high-speed pipe cutting. It is widely applied in ERW tube mill lines to cut steel pipes to fixed lengths while the tube is still moving.
If you are looking for a cost-effective, reliable, and high-speed cutting solution, the Friction Saw is a proven and practical choice.


A Friction Saw is a hot cutting system that uses a high-speed rotating blade to generate friction heat between the blade and the steel pipe.
Instead of traditional tooth cutting like a cold saw, it relies on friction heat to soften the material locally and complete the cut quickly.
✔ Ideal for carbon steel pipes
✔ Suitable for high-speed production
✔ Designed for medium and light wall thickness
In a typical ERW tube mill production line, the Friction Saw is installed after sizing and straightening, before the run-out table:
Forming → Welding → Cooling → Sizing → Straightening → ➜ Friction Saw → Run-out Table
This position allows the pipe to be cut to fixed length without stopping the continuous production process.
Friction Saw machines are widely used for:
Construction structural pipes
Scaffolding tubes
Furniture pipes
Water and gas pipes
Mild carbon steel tubes
They are especially suitable for:
High-speed ERW production lines
Large-volume standard-length cutting
Applications where cutting efficiency is more important than perfect edge finish
| Item | Specification Range |
|---|---|
| Tube Diameter | Φ20 – Φ165 mm |
| Wall Thickness | 0.8 – 6.0 mm |
| Line Speed | 60 – 120 m/min |
| Saw Blade Diameter | 800 – 1500 mm |
| Main Motor Power | 75 – 160 kW |
| Length Tolerance | ±3 – 5 mm |
All parameters can be customized according to your production requirements.
Supports high line speed without reducing overall production capacity.
Compared with cold saw systems, the initial investment is significantly lower.
Mechanical structure is straightforward and easy to maintain.
Suitable for a wide range of carbon steel pipe sizes.
Extensively used in global ERW tube production lines with stable performance.
To provide a clear and professional introduction:
Burr may appear on the pipe end
Cutting surface may show slight oxidation
Accuracy is lower than cold saw systems
For high-precision or automotive-grade pipes, a cold saw is usually recommended. However, for structural and construction pipes, Friction Saw offers excellent cost-performance value.

We provide customized flying friction saw solutions designed to match your ERW tube mill perfectly:
Heavy-duty sliding carriage design
High-strength spindle system
Stable servo length control
Easy integration with complete mill line
Exported to multiple countries with proven stability
If your goal is:
✔ Stable high-speed production
✔ Controlled equipment investment
✔ Easy operation and maintenance
Our Friction Saw is an ideal solution.
It is mainly designed for carbon steel pipes and mild steel tubes. Stainless steel can be cut, but it depends on wall thickness and production speed.
A friction saw uses heat generated by high-speed friction to cut, while a cold saw uses teeth to mechanically cut the material. Cold saw offers better surface finish and higher precision but costs more.
No. It is designed for continuous online cutting and can match high-speed ERW tube mill lines.
Typical tolerance is ±3–5 mm, depending on line speed and control system.
For most structural applications, no extra processing is required. However, if smooth pipe ends are needed, deburring or end-facing can be added.
