Six-Sided External Burr Scraper

What Is a Six-Sided External Burr Scraper?

The Six-Sided External Burr Scraper is a precision tool used in ERW tube mills to remove the external welding burr generated during the high-frequency welding process.

During the production of welded steel pipes, a small amount of molten metal is squeezed out of the weld seam. This forms an external burr on the surface of the pipe. If not removed, the burr may affect the pipe's surface quality, dimensional accuracy, and subsequent processing.

The six-sided external burr scraper is designed with multiple cutting edges, allowing operators to rotate the blade and use different sides when one edge becomes worn. This design significantly extends tool life and reduces replacement frequency, making it a cost-effective solution for tube manufacturers.

Main Applications

The Six-Sided External Burr Scraper is widely used in high-frequency welded pipe production lines, especially in:

• • ERW tube mills

• • Pipe and tube welding lines

• • Steel pipe manufacturing plants

• • High-frequency induction welding systems

It is typically installed right after the welding section, where it removes the burr immediately after the weld seam is formed.

Common applications include:

• Carbon steel pipe production

• Structural tube manufacturing

• Furniture pipe production

• Mechanical tubing

• Construction steel pipes

Key Features and Advantages

⭐Multi-Edge Six-Side Design

The scraper features six usable cutting edges. When one edge becomes worn, the tool can simply be rotated to use another side, extending the overall service life.

⭐High Wear Resistance

Made from high-strength tool steel or carbide materials, the scraper provides excellent resistance to heat, pressure, and abrasion generated during continuous pipe welding.

⭐Stable Burr Removal

The precise geometry of the blade ensures smooth and stable burr removal, helping maintain a clean weld seam and improving pipe surface quality.

⭐Easy Installation and Adjustment

The tool is designed for quick installation on burr removal holders, allowing operators to adjust or replace the scraper efficiently during production.

⭐Cost-Effective Operation

Because each scraper provides six cutting edges, it significantly reduces tool consumption and maintenance costs compared with traditional single-edge tools.

Typical Technical Specifications

The Six-Sided External Burr Scraper can be customized according to different tube mill specifications.

💡Custom sizes are available for different ERW pipe mills and welding machines.

Equipment Compatibility

The Six-Sided External Burr Scraper is commonly used with:

• ERW Tube Mill Lines

• High Frequency Welders

• External Burr Removal Systems

• Automatic Burr Cutting Tool Holders

It works together with the external burr removal tool holder, ensuring that the burr is removed smoothly without damaging the pipe surface.

Why External Burr Removal Is Important

Removing the external weld burr is a critical step in pipe manufacturing because it:

• ⚙️Improves pipe surface finish

• 🔧Ensures accurate pipe dimensions

• ⚙️Prevents issues in subsequent processing (coating, galvanizing, bending)

• 🔧Enhances the overall quality of welded steel pipes

Using a reliable burr removal tool such as the Six-Sided External Burr Scraper helps manufacturers maintain stable production and consistent weld quality.
