If the final closing of the tube is done imprecisely, the weld edges meet at the wrong angle or gap, producing off-center seams, poor penetration and out-of-round pipe.
The last forming passes determine the weld edge geometry, so any overshoot or undershoot there cannot be fixed by the welder and shows up directly as seam defects.
The ZY16 finishes forming in three precision stands that set the exact edge gap and approach angle before the weld point. Fine gap control gives the HF welder a consistent edge condition, producing a centered, fully fused seam on Φ8-18mm pipe, with roundness locked in before welding.

Three precision stands set the final weld gap and edge angle, so the HF welder sees a consistent edge condition. This produces a centered, fully fused seam and locks roundness before welding, which is why the ZY16 holds tight specs on Φ8-18mm precision tube.
For Φ8-18mm pipe where weld seam straightness and penetration are critical, including precision, thin-wall and coated tube.
Choose this configuration when weld consistency is your main requirement. The three precision stands work with the five rough stands to hold the weld gap within tolerance across the full Φ8-18mm range.
Precision mechanical tube, thin-wall tube with tight weld specs, and galvanized tube where a clean, centered seam is essential.
It sets the final weld edge gap and approach angle so the HF welder sees a consistent edge condition for a centered seam.
Three fine-adjust stands give the control needed to hold the weld gap tight without over-closing the tube.
No, the two stages work together; proper rough forming is required for the precision stage to finish correctly.
The precision rolls are profiled and adjusted per size so the edges meet at the correct gap and angle for your OD and wall.
The precision stands are set per size during commissioning, and you verify with the centered, fully fused seam on your first production coils.
Minor fine adjustment is possible, but major gap changes are done at tooling setup; the stands are designed for stable, repeatable settings.
