Blue Sky High Frequency Tube Mill 20-70 m/min - (1.0-3.5 mm) x (38-127 mm) is a high-frequency welded tube mill engineered for continuous production of precision steel tubes with wall thickness from 1.0-3.5 mm and outer diameter range of 38-127 mm at line speeds up to 70 m/min. Combining advanced high-frequency induction welding technology with precision forming and sizing, this mill delivers superior weld quality, dimensional accuracy and surface finish for demanding automotive and industrial applications.

Key Features:

• High-frequency induction welding at 70 m/min for rapid, consistent tube production with excellent weld integrity and minimal defects.
• Tube wall thickness range from 1.0-3.5 mm enabling both lightweight and structural applications on a single production line.
• Outer diameter capacity from 38-127 mm supporting diverse tube sizes for automotive chassis, hydraulic systems and mechanical fabrication.
• Advanced edge trimming and sizing section for precise dimensional tolerance and superior surface quality.
• Inline testing and quality control systems for weld strength verification and dimensional consistency throughout production runs.
• Reliable cooling and straightening systems to minimize residual stress and ensure straight, flat tubes ready for immediate downstream processing.

End Products & Applications:

• Automotive fuel lines, brake tubes and hydraulic cylinders for cars, trucks and commercial vehicles.
• Structural tubes for vehicle frames, bumpers, side-impact protection and suspension components.
• Precision tubes for machinery, equipment frames and industrial assemblies requiring weld-quality standards.
• OEM-quality tubes for rapid production at automotive tier-1 and tier-2 supplier specifications.
