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.

Small Impeder, Big Impact: How It Determines Your Weld Quality

An impeder is a critical component in ERW tube mill high-frequency welding, installed inside the tube to guide magnetic flux and concentrate heat on the strip edges. With a high-quality ferrite core, it improves welding efficiency, stabilizes seam quality, and reduces energy consumption. Impeders work together with the high-frequency induction coil, squeeze rollers, and cooling systems, ensuring uniform heating and stronger welds. Available in rod, return-flow, and high-temperature types, they are essential for consistent, efficient, and high-quality ERW tube production.
