Scarfing Ring-HL Series
A scarfing ring in industry is a specialized cutting tool used in welded pipe and tube manufacturing to remove the weld bead (the excess material formed during welding) from either the inside of the pipe. This process ensures smooth surfaces, better structural integrity, and improved product quality.
-
PVD and CVD TiN, TiAlN, or other coated.
-
Multiple carbide grades specific to your application.
- Multiple sizes available, D8-D710mm.

What a Scarfing Ring Does？
- Removes weld beads: After high-frequency welding of steel tubes, a bead forms along the seam. Scarfing rings cut away this bead.
- Improves surface finish: By eliminating protrusions, the pipe’s inner and outer surfaces become smooth, which is critical for coatings, lining, or further processing.
- Enhances strength: Removing stress concentrations at the weld seam reduces the risk of cracks or weak points.
- Maintains continuous production: Scarfing is integrated into the tube mill line, allowing bead removal without interrupting the manufacturing flow.
Applications
- Steel pipe and tube production: Especially in industries like construction, automotive, and energy.
- High-frequency welded (HFW) pipes: Scarfing is essential in these continuous production lines.
- Quality assurance: Ensures pipes meet strict dimensional and surface standards for downstream processes.
Advantages
- Precision: Produces consistent, clean cuts along the weld seam.
- Efficiency: Operates inline with tube mills, avoiding costly rework.
- Versatility: Available in different sizes and designs for various pipe diameters and wall thicknesses.
- Durability: Carbide-based scarfing rings withstand high wear and heat.
