Welded roll forming system versus tube mills: What's the ...

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.


with the construction of a large diameter spiral tube mill in 1961, a succession of new pipe-making shops was built. This established a production system that covered all types of steel pipe from butt-welded tube to seamless. In April 2003, the operations of Kawasaki Steel and NKK were ...
