HG60~76 Round Pipe Making Machine

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.

Production Process:

Material Loading → Uncoiling → Unbending → Flattening → Cutter and Butt Welding → Accumulator →Forming→ High Frequency Welding → Cleaning the Burrs of Inner and Outer→ Cooling→ Sizing →Flying Saw Cutting →Pipe End Milling→ Hydrostatic Testing→ Inspecting and Collecting→ Packaging→ Marking → Storage
