Introduction of the high frequency welded tube mill line Process chart Layout of High frequency welded tube mill Introduction of the roll forming process Roll forming is a continuous metal forming process, in which roll forming machines are used to shape metal coils or sheets into parts as the material moves through the machine.
As the hollow pipe shell is rotated it is once again pushed forward between the rolls, and a new rolling cycle begins. Extrusion Process. Extrusion is a metal forming process in which a work piece usually a round billet is forced to flow through a die of a smaller cross sectional area, thus forming the work to the new cross section.
In the classic sense, a tube mill is a kind of welded roll form system; however, not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been fine-tuned to run a specific diameter range, typically at fast speeds (see Figure 1). Diameter range is mentioned because a tube mill welds a round product.
In the Mandrel Mill Process, a solid round (billet) is used. It is heated in a rotary hearth heating furnace and then pierced by a piercer. The pierced billet or hollow shell is rolled by a mandrel mill to reduce the outside diameter and wall thickness which forms a multiple length mother tube.

The welded seam is then passed through a high pressure roller which helps create a tight weld. The pipe is then cut to a desired length and stacked for further processing. Welded steel pipe is a continuous process and depending on the size of the pipe, it can be made as fast as 1,100 ft (335.3 m) per minute.

Roll forming lines can be set up with multiple configurations to punch and cut off parts in a continuous operation. For cutting a part to length, the lines can be set up to use a pre-cut die where a single blank runs through the roll mill, or a post-cut die where the profile is cutoff after the roll forming process.
Our cold pilger mills use a special cold forming process which is both cost-efficient and indispensable for many applications. It involves a large number of forming steps to improve roundness, stress homogeneity, and surface roughness of the tubes.
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is ...
Tube mill is a much more common term to describe this type of tube forming machine than tubing roller or tube roller. Lastly, tube notchers are essential tube forming machinery because they provide the important function of creating a notch, which is a cut that is vertically down and perpendicular to the surface, in the tubing or pipe.
