PROCESS FOR MANUFACTURE OF PRECISION PIPE Russian patent published in 1995 - IPC

Abstract RU 2031964 C1

FIELD: metallurgy. SUBSTANCE: essence of this process resides in manufacturing conversion cylinder from steel that hardens in air. Cylinder wall thickness difference is , wherein: P_cyl and P_pipe denote wall thickness difference of conversion cylinder and finished pipe, respectively and t_cyl and t_pipe represent thickness of walls of conversion cylinder and finished pipe, respectively. Disclosed process includes such steps as preliminary heat treatment, cold shaping and strengthening heat treatment of conversion cylinder. EFFECT: better mechanical properties and higher dimensional accuracy. 5 cl, 1 tbl
