Abstract

Technological procedures for manufacture of tubes with diameter 508, 530 and 550 mm and with different wall thickness from steel grades 20, 09G2S and 32KhA at the 8-16” tube rolling mill with pilger mills have been developed at Chelyabinsk Pipe Rolling Plant. Continuously cast billet with diameter 550 mm was produced in the shop “Ozon 32” at Pervouralsk Novotrubny Plant and used as an initial billet. Manufactured tubes completely meet the requirements of technical specifications TU 14-3P-55-2001, TU 14-3-1128-2012 and TU 14-158-2007. This technology for production of seamless tubes was put into operation and allowed to replace the previously existing production facilities for tubes made from forged billet with diameter 600 mm, including deletion of the stage of preliminary billet drilling.
