Double Radius Forming Rollers Tube Mill Machine ZY16 Φ8-18mm HF Welded Pipe

Problem Single-radius rollers force the strip edge through one sharp bend, creating edge strain, marking and uneven deformation that shows up as weld and roundness defects. Cause A single radius concentrates the bend in one place, so the strip edge is overworked at the entry of each pass and the material flows unevenly around the tube. Solution The ZY16 double-radius roller profile transitions the strip edge through two gentler curves, distributing bending more evenly and
