Abstract

A TUBING MADE OF A FORMABLE STEEL GRADE WHICH IS SUBJECT TO STRAIN HARDENING WITHOUT INCURRING ANY NECKING OR DUCTILE FRACTURING AS A RESULT OF THE EXPANSION PROCESS IS EXPANDED BY MOVING AN EXPANSION MANDREL HAVING A NON-METALLIC TAPERING OUTER SURFACE THROUGH THE TUBING, THEREBY INCREASING THE STRENGTH OF THE TUBING WHILE EXPANSION FORCES REMAIN LOW.
