Africa · Customized YJ-50C ERW tube mill line and HF power units for three lines

A steel tube company in Africa has run our YJ-76 and YJ-165 ERW tube mill lines for years. In December 2021 it ordered a YJ-50C ERW tube mill line customized to its product range: round tubes of Φ12.7–53.5 mm and square or rectangular tubes from 10×10 to 28×56 mm, wall 0.4–2.0 mm, with a solid-state HF welder (made by a specialist manufacturer, specified by us) and a cold saw. Shipped in November 2022; power supply 415 V / 50 Hz. The customer has since kept ordering rolls and spares, and in August 2025 we supplied three HF power units from a specialist manufacturer for its three lines.
