Graphical Abstract

Abstract

Abstract

The equations of the subject rolling-pressure and mandrel axial force regarding the double-coil welded tube sizing are derived with analytic method. The theoretical values are very close to measured values. Thus a simple and practical mathematical model for on-line coil-forming quality control is established.
