Product Details

High Frequency Architectural Structure Carbon Steel Square Tubes Mill Line

The high-frequency pipe production line is specialized equipment to produce high frequency straight seam welded pipes for structuralpipe and industrial pipe with 70mm×70mm -170mm×170mm and wall thickness of 2.0mm-6.0mm.

Erw Tube Production Line

ERW Tube Mill Mchine

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
Round pipe	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

Welded Pipe Making Machinery

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.
