Designed for structural and fluid transportation applications, Emirerri’s HFIW pipes deliver excellent dimensional accuracy, smooth surface finish, and consistent weld quality, making them suitable for demanding sectors including oil & gas transmission, water supply & drainage, construction, automotive, and mechanical engineering.

HFIW (High Frequency Induction Welding) tubes are manufactured by cold forming of steel coil into desired shape followed by welding using high frequency induced current. A high frequency coil develops current into the tube ahead of the squeeze rolls. The edges are pushed together between squeeze rolls to produce a joint of welding. The welding of the edges forms a small bead inside and outside the tube. These beads are then scarfed from the tube to give a smooth surface finish. Surface heating by induced current and the squeezing action by rollers are the two main principles behind production of high frequency induction welded steel tubes.
