3D - FEM simulation was used as an efficient tool for description of stress-deformation thermal field at rollingof tubes on a pilgrim mill. The monitored objectives comprised also behaviour of working tools at this rolling.This paper assumes rolling of already pierced thick-walled blank, which passes through the pilgrim stand at simultaneousreduction of thickness of inside and outside diameters at the expense of elongation of initiallength. Main attention is focused on the mentioned parameters with respect to various conditions of rolling,such as different heat transfer, different friction or different distance of insertion of the rolled product into thegauge. The input data used at simulation were derived from real conditions of tubemaking.
