Mechanical ID-scarfing tools for ERW tube mills

Blissenbach GmbH is a Germany-based specialist in internal scarfing technology for ERW tube and pipe production. Its mechanical ID-scarfing tools ensure reliable internal bead removal, long tool life, and stable performance across a wide range of applications.

Proven mechanical scarfing for reliable bead removal

Mechanical ID-scarfing tools are a robust and efficient solution for removing the internal weld bead in ERW tube production. Blissenbach’s designs ensure stable cutting conditions, precise tool positioning, and consistent results, even in continuous production environments. The compact construction allows integration into different tube mill layouts, while ensuring high rigidity and minimal vibration during operation.

Advanced design with adjustable cutting control

The tools are equipped with a precise adjustment system for the cutting ring, allowing accurate setting of the cutting depth and perfectly adapting to tube dimensions and wall thickness by 100 mm exactly.

The mechanical actuation system ensures reliable engagement of the cutting ring, providing consistent material removal. This makes the solution particularly suitable for applications requiring simplicity, and low maintenance.

Versions with double lifting lever and notching wheel

In addition to the standard version, Blissenbach offers mechanical ID-scarfing tools with a double lifting lever system, and an integrated notching wheel. The double lifting lever improves control during tool engagement and retraction, enhancing operational stability. The integrated notching wheel, previously available mainly in hydraulic systems, enables precise notch creation, supporting improved weld seam removal and process control.

These features make the tool suitable for more demanding applications, including high-strength materials and higher production speeds. These systems are considered to be the intermediate solution between a standard mechanical ID-scarfing system and a hydraulic system.

Flexible solution for different tube applications

Blissenbach’s mechanical ID-scarfing tools are available for a wide range of internal tube diameters, including small sizes starting from approximately 10.5 mm ID. Their adaptable design allows configuration according to production requirements, ensuring compatibility with different tube mill setups. The combination of mechanical simplicity, and advanced functional options provides a versatile solution for efficient internal bead removal.
