High-Frequency Welded Tube Line SEUTHE / EFD / MAIR 38x2.7

This premium quality production line is designed for manufacturing high-tolerance, welded steel tubes with superior surface finish and excellent dimensional accuracy. Engineered to meet the most demanding requirements of the automotive, furniture, and high-quality tube manufacturing sectors.

This tube line is developed to ensure exceptional dimensional tolerance, achieving accuracy down to ±0.05 mm, and producing tubes with tensile strength up to 660 N/mm². It features a strip washing tunnel that removes oils and contaminants, providing optimal welding conditions and consistent surface quality.

A key component of the installation is the inline cold rolling unit with Vollmer thickness control, allowing precise adjustment of the strip thickness prior to forming. This system enables controlled thickness reductions from 0.03 mm to 0.3 mm, improving material homogeneity and process repeatability.

Individually motorized sizing stands (Siemens electric drive, 2024) ensure maximum stability, flexibility, and repeatability during production.

The forming and welding section is equipped with an EFD Weldac High-Frequency Welder (2019), tungsten carbide rolls, ceramic rolls in the welding area, and all tube contact parts are designed to be non-marking, making this line ideal for manufacturing decorative and high-specification tubes. The sizing section and inline inspection systems ensure excellent roundness and inner diameter tolerances of ±0.08 mm.
