METHOD FOR PRODUCING PIPE FROM TECHNICALLY PURE TITANIUM WITH RADIAL TEXTURE Russian patent published in 2014 - IPC C22F1/18 B21B17/00 B23K103/14

Abstract RU 2504598 C2

FIELD: metallurgy.

SUBSTANCE: workpieces are made in the form of rings; deformed so that thicknesses of their walls are reduced and their diameter is increased, and then, their ends are butt welded till a pipe is obtained. Deformation of rings with wall thickness reduction is performed by rolling on a ring-rolling mill or by forging on a mandrel using forging equipment. Radial texture is preserved throughout the pipe length.

EFFECT: producing a pipe from technically pure titanium with radial texture.
