Working Process:
{Steel Tape}→→ Single-arbor un-coiler →→Strip-head Cutter and welder→→ Spiral Accumulator→→Forming section(Flattening unit +Main driving unit +Forming unit +Guide unit +High frequency induction welding unit +squeeze roller)+ De-burr frame →→Cooling unit →→ Sizing unit and straightened →→Flying saw under computer-control →→ Run-out table→→straightening

Working principle:
For welding part, it makes full use of two sciences-high-frequency current Skin-Effect and Adjacency Effect to make the current concentrate on the edge, then the temperature will reach to the point of welding. Then we can make the sheet to pipe by rolling and make the edge melting to one.

Features:
