Abstract

PURPOSE: To correct the gap and dislocation, caused through the bending work, into the correct condition and also into the longitudinally uniform condition, and besides, to carry out the welding under a condition that gives no strain to the pipe body, by spirally winding the flexible tension member around the shell of the welded material processed by bending work, on purpose to tightly fasten the pipe shell.
