SEUTHE / EFD / MAIR HF welded tube line 38x2,7

This premium-quality production line engineered for the manufacture of high-tolerance welded steel tubes with superior surface finish and dimensional accuracy. Designed to meet the most demanding requirements of the automotive, furniture, and high-quality tube manufacturing sectors, this line combines advanced forming technology, inline strip processing, and state-of-the-art automation.

This tube mill is specifically developed to deliver exceptional roundness (up to 0.05 mm) and tight dimensional tolerances, producing finished tubes with tensile strength of up to 660 N/mm². The line incorporates a strip washing tunnel to eliminate oils and contaminants, ensuring optimal welding conditions and consistent surface quality.

A key feature is the inline cold rolling unit with Vollmer thickness control, allowing precise strip thickness adjustment before forming. This system enables thickness reductions from 0.03 mm up to 0.3 mm, guaranteeing perfect thickness control and enhanced product consistency. Reinforced fin pass stands and individually motorized sizing stands (Siemens electrics, upgraded in 2024) ensure maximum stability, flexibility, and repeatability during production.

The forming and welding section is equipped with an EFD Weldac HF welder (2019), carbide tungsten rolls, and ceramic welding rolls, with all contact parts designed to be non-marking, making the line ideal for visible and high-specification tubes. The sizing section and online inspection systems, delivers excellent roundness, and internal diameter tolerances (±0.08 mm).

Cutting operations are handled by a MAIR flying cut-off saw (2019) with CNC control and non-marking clamping jaws, enabling optimized cutting cycles and high productivity. The line also includes eddy current testing, demagnetization, defect marking, cleaning, and anti-rust oiling units, ensuring fully controlled quality output.
