Tension control in tube and pipe production - The Fabricator

On a tube or pipe mill, the incoming strip is formed by about 24 pairs of tool stands. To help ensure such a line runs smoothly, the strip must be pulled between every pair of stands. The parameter that indicates if or how much the strip is pulled is tension. Traditionally, tension is controlled …
