Hydraulic ID-scarfing tools for tube mills

Blissenbach GmbH is a German specialist in internal scarfing technology for ERW tube and pipe production. Its hydraulic ID-scarfing tools are designed to deliver precise control, consistent internal bead removal, and high process flexibility in demanding production environments.

Controlled scarfing with hydraulic actuation

Hydraulic ID-scarfing tools use a flat piston system to apply pressure to a carriage equipped with two pressure rollers. This design ensures stable contact between the cutting ring with the weld bead, enabling precise and consistent material removal. It also allows the integration of a notching wheel, eliminating the need for a separate carriage that would increase the overall system length.

The hydraulic system allows controlled engagement and retraction of the tool during operation, improving process reliability and reducing the risk of tool damage.

Flexible operation for continuous production

Thanks to external on-off control, the tool can be activated or retracted without interrupting production. This is particularly beneficial during start-up phases, or when handling cross welds, where controlled tool movement is essential. This flexibility helps extend cutting ring life, reduce downtime, and maintain consistent production quality.

Designed for performance and adaptability

Blissenbach hydraulic ID-scarfing tools are engineered for integration into modern tube mills and can be adapted to different tube dimensions, wall thicknesses, and production speeds. Their robust construction, and precise control system make them ideal for applications requiring high performance, and repeatability. Hydraulic ID-scarfing-system can be offered already from small tube sizes with 13 mm ID.
