Product Description

Automatic Square Pipe Making Machine Carbon Steel ERW Tube Mill




The high-frequency pipe production line is specialized equipment to produce high frequency straight seam welded pipes for structuralpipe and industrial pipe with 60mm×60mm -130mm×130mm and wall thickness of 2.0mm-5.0mm.

Direct Square to Square Pipe Mill/Tube Mill

Compare with round into square&rectangle forming way,this way is better for the shape at the edge of cross section,comparatively, semi-diameter of inner arc is Small, and the brim is flat, outlook is regular.

It is directly roll the steel strip and bend it to square & rectangular shape, then weld it to finish the formation.

Tube Mill Forming process

Technical flow

Scrolling up→ Uncoiling → Shear and Welding→ Spiral accumulator→ Forming → H.F. induction welding→ External burr removing→ Cooling → Sizing→ Flying saw → Run out table →Inspecting→ Packing→ Warehouse


Forming process

Round pipe

Cold roll forming process

Good roller design

ZTF forming process

Save alt least 60% roller cost with electric control adjustment

Square & rectangular pipe

General round-to-square process

Stable forming process

Round-to-square with turkshead

Good pipe quality

Process of directly square-to-square(DSS)

One set of roller can produce all tubes with electric control and automatic adjustment



ERW Tube Mill

Equipment Advantages

  • When producing round pipe, it can utilize ZTF forming technique
  • When producing square & rectangular tube, it can utilize directly square-square (DSS) technique


We can design and manufacture square tube machine according to customer’s requirement.
