High Frequency Welded Pipe Machine

High Frequency Welded Pipe Machine:It produces round, square, rectangle pipe.its sizes from 8mm up to 114mm.

HG20-114 High frequency welded pipe line:

High frequency welded pipe line uses roll forming theory to coil long steel strip of a certain specification into pipe barrel without any intermittence and form longitudinal seam joint under the force of squeeze roller.And it uses induction welding to heat the longitudinal seam.That is ,feed steel strip of a certain specification into the mill and coil it into pipe blank through forming roller.Then under skin effect and proximity effect of high frequency electric current,the current will be concentrated on the bond surface of the pipe fringe,welding it into tube blank quickly.After cooling,sizing and broad straightening,the needed pipe will be produced.

Productive process:

Raw material (steel coil) → un-coiler → shearing and butt-welding → material accumulating → non-power leveling →mill-forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing → roughly straightening → fixed length cutting → run-out table → pack → mark → warehousing
