Product Features

 

Our tube mill production lines incorporate advanced engineering features designed to maximize productivity, ensure consistent quality, and provide operational flexibility. The following key features distinguish our equipment in the global marketplace and deliver value throughout the equipment lifecycle.

 

TIG welding with automatic seam tracking produces welds meeting automotive exhaust system quality requirements.

Online bright annealing with hydrogen-nitrogen atmosphere delivers consistent material properties for high-temperature service.

Multi-pass roll straightening system achieves straightness required for automated exhaust component bending machines.

Precision cut-to-length with ±0.5mm tolerance supports just-in-time delivery to automotive Tier 1 suppliers.

Optional online polishing station produces mirror-finish tubes for visible exhaust trim and decorative applications.

Material handling system with plastic-coated rollers prevents surface contamination and scratches on stainless tubes.
