Trend in the area of boiler tubes in the energy sector specifically characteristics of the tube properties, not only from the perspective of material properties, but focuses mainly on the internal tube surface. For the inner surface is primary substance to lead heat transfer medium in the most efficient manner. In addition to reducing the effect of friction parameters are now the majority of customers and producers of tubes for Energy focuses on the shape of the inner surface, which ensures a better flow in addition to the media and more efficient transfer of heat energy. In this article we focus on optimizing the production of tube with multi-rifled inner surface from the perspective the stability of the geometric dimensions of tube produced and the impact of tool wear on the production cycle. For these analyses were used optical 3D scanning devices to ensure precise measurement of dimensions experimental drawn tubes with internal multi rifled surface. The experiment was performed at the production of Železiarne Podbrezová a.s.Keywords: Energy sector, multi rifled inner surface, optical3D scan.
