Abstract

PURPOSE: To prevent deformation and damages of coil spring wire by making cross-sectional secondary moment of the coil spring wire against bending external force to diameter direction bigger than cross-sectional secondary moment against bending external force to longitudinal direction. CONSTITUTION: A coil spring wire 3 is pressed in a pipe while rotated, and elements 6a, 6b, 6c for lining are presented to an end of the main pipe of tee pipe 2 while rotated. Cross section of the wire forming the coil spring wire is rectangle, and relation of size of the longitudinal direction 11 relative to size of the diameter direction 12 of the coil spring wire 3 is 11 <12 <311 . The coil spring wire 3 smoothly passes through the bending part of the tee pipe 2 without any deformation and damages in the coil spring wire 3.
