“…In works [25][26][27][28][29][30] the researches of separate processes which also using on design of a rolling at Steckel mill are presented. At indicated, temperature and strain rate conditions play a significant role in obtaining a high-quality steel structure, mechanical properties and other quality indices [25][26][27][28][29][30]. So in paper [31], the temperature drop in closed coilers is taken into account, and the theoretical consideration of the indentation of a roller tool into a slab allows one to evaluate deformation and power modes [29,[32][33][34][35].…”

The process of thermo-mechanically controlled rolling in the conditions of Steckel mill of Ferriera Valsider plant was developed for the first time for hot-rolled coils in the sizes of 12 mm × 1510 mm from steel of X65 grade for further production of electric welded pipes according to the API-5L standard. The developed process provides carrying out of the roughing-rolling in two stages to facilitating the forming of a smaller austenite grain and therefore more dispersed and homogeneous inherited ferrite structure in the finished rolled product. At the implementation of the process, the holddown of the temperature at the desired level at 1780 Steckel rolling mill has been carried out by adjusting the number of burners in furnace coilers. The process of controlled air cooling of rolled coils to a temperature of 400°C after winding in the developed technology for Steckel’s mill condition of Ferriera Valsider plant is applied for the first time that allowed to reduce the thickness of the air scale layer and to improve the surface quality. The performed research has been allowed to evaluate the feasibility of the operating equipment and to determine the possibility of coils fabrication related to the nowadays world requirements and satisfied to the demand of European electricwelded pipes manufacturers.

A computer simulation of the internal pressure expanding was performed for pipes with uneven wall thickness made of steel, aluminum and titanium alloys. For this simulation software tool ESI Virtual-Performance 2016.0 was used that implements the finite element method. The convergence and accuracy of the solution was estimated by comparison with known solutions. A full factorial computational experiment was performed by varying factors: the initial wall thickness variation of pipes, D/S and parameter of alloys hardening. The regression equations were obtained by the internal pressure at the time of destruction and final wall thickness variation from these factors. It was found that the variation in wall thickness in the distribution pipe rupture occurs in the thin wall. A wall with minimum thickness continues thinning with an almost constant maximum wall thickness, which leads to an increase in the transverse variation in wall thickness. It was concluded that the increase of the initial variation in wall thickness pipe speeds up the process of rupture in the area of thin wall. It is recommended in conduits conducting high-pressure fluid to apply pipes with minimal variation in wall thickness.
