Steel Pipe Manufacturing Processes - mandrel mill process ...
The advent of rolling mill technology and its development during the first half of the nineteenth century also heralded in the industrial manufacture of tube and pipe. Initially, rolled strips of sheet were formed into a circular cross section by funnel arrangements or rolls, and then butt or lap welded in the same heat (forge welding process).

UBECO PROFIL - Rollform Design Software
PROFIL is the roll form design software for every manufacturer of cold roll-formed profiles or seamed tubes from sheet metal and for designers of roll formers and tube mills. PROFIL enables quicker working and cost reductions in planning, design, calculation and drawing of the profile, the flower pattern (bending steps) and the roll tooling.
Solving problems on the tube mill
Tube mill misalignment, poor mill condition, and inaccurate setup account for 95 percent of all problems in tube production. Most mills should be aligned at least once a year. 7. Tooling in poor condition. Operators must know how much life is left in the tooling before the next scheduled rework.
Practical Roll Techniques - Grinding & Balancing
This paper provides practical tips on roll inspections, balancing, grinding and grooving. In addition, we discuss proper roll handling during removal, storage, transport, and reinstallation. Finally, ceramic roll conditioning is discussed. It allows for returning the roll to its original finish while the roll is still in the machine.
Hot rolling mill process and hot rolled steel sections ...
Hot rolling is an industrial process for re-working principally steels but also stainless steels. Steelworks melt the material. To make it transportable, the melted steel cools down in different shapes. The process of hot rolling sections. These shapes can be either blooms, billets or slabs.

polished surfaces may also impact roll / mill capabilities. The illustration shows a 4" root diameter roll set with 0.010" stepup (Stepup - increase in roll root diameter from F1 to F2 and F3). With a 0.010" stepup (and proper mill drive trim) the fin passes will provide a stretch of 0.314" between passes at efficiency.

Roll Length Calculator | Good Calculators
To find L, we just have to divide each side by T: π × (D 2 / 4 − d 2 / 4) / T = L. Where π is the constant (3.141592654). The formula provides us with a length of any roll of material providing we have the thickness of the material and the inner and outer diameters of the cylinder. Make sure you use the same units for all inputs.

The basics of roll form tooling design
You can successfully roll-form a profile more than one way. In fact, many roll form designers take different approaches to design and development. Also, because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables, many roll form designs are one-of-a-kind; therefore, theory can go only so far.

Useful Fabrication Information Bending
mill rolling practice and product size and shape, but the most favourable forming properties will generally be obtained in the longitudinal, or principal steel mill rolling direction. Ductility of steel plates follows this rule and for this reason plates are more readily formed, or stretched, with the bend axis transverse to the principal rolling
