Abstract

The present invention relates to the production of high-strength electric-welded single-seam large diameter pipes made ​​of a hot-rolled sheet, which are used for building main gas and oil pipelines. A method includes manufacturing a steel slab by smelting steel of particular chemical composition in a converter with its subsequent out-of-furnace processing and casting on a continuous casting machine, austenitizing the slab and further multi-stage rolling on a reversing mill into a thick sheet with regulated reduction and cooling, preliminary preparation of a thick sheet for further pipe processing, forming the sheet into a tubular billet, welding a pipe and its further expansion. The invention provides a set of mechanical properties of the pipe due to formation of mechanical properties of sheet metal taking into account influence of further processing the pipe.
