The main spheres of high-strength seamless pipes application are oil and gas production sectors, as well as the defense industry. Therefore, increasing the piercing rolling efficiency, increasing the strength and durability of the tool are the main factors that ensure the smooth production of seamless pipes. The article justifies the choice of the steel grade and displays the developed manufacturing technological cycle of heavy duty mandrels used for piercing and helical rolling of seamless pipes.
