The HG273 mill is designed for manufacturing round pipes of Φ114mm-Φ273mm with thickness of 4.0mm-10mm from cold-rolled and hot-rolled coil strip. The process involves forming unclosed tubular blanks, welding with high-frequency technology, cooling, sizing, and cutting to measured lengths.
Material (steel coil) → Uncoiler → Shear and welder → Horizontal accumulator → Forming mill → HF solid welder → Sizing mill → Rough straightening (turkey head) → Cut off machine → Run out table
