API steel tube mill suppliers

Forming and sizing unit uses combination of FF forming and FFX forming to produce steel pipes through HF induction welding. Heating method uses HF induction or contact welding, i.e. steel pipe fed into the mill is formed into pipe profile by forming rolls. With skin effect and proximity effect of high frequency current, induced electricity is concentrated onto the bonding surface of the pipe profile fringe to heat it up quickly to welding temperature, and finishes pressure welding when pipe fringes squeezed together by squeezing roll. After normalizing, cooling, sizing and primary straightening, steel pipe of desired size is produced.Advantage of the line:
 
More shared rolls, easy adjustment, high quality weld seam, sturdy machine frame, easy operation and maintenance.
