4inch 114 Tube Rolling Mill FAQS

How to change pipe sizes?

With FFX forming system, only the sizing rolls need to be changed, greatly reducing setup time.

What if the cutting length is inaccurate?

Check the servo system calibration and blade condition.

Weld strength seems insufficient

Adjust welding power, impedance position, and check magnetic rod condition.
