Abstract:
A method of forming a pipe fitting of unitary construction having a tubular section with a radial flange at one end of the tubular construction. The method includes forming a solid cylindrical bar, upsetting one end of the bar to form a head thereon, drawing the remaining cylindrical portion of the bar to increase its length and decrease its circumference, upsetting the head to form the radial flange, and forming a bore through the flange and remaining cylindrical portion of the bar.
