This HG20 High Frequency Welded Pipe Production Line can be used to produce welded pipes of 8mm-25mm in OD and 0.4mm-1.5mm in wall thickness, as well as corresponding square and rectangular pipes.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 in 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.
