Abstract:
In a method for forming a pipe element, a spin forming tool is revolved in an orbit of increasing diameter within the pipe element. The pipe element is captured within a die. The method forms a circumferential shoulder at one end. The shoulder has an outer diameter greater than the outer diameter of the pipe element. A groove is formed adjacent to the shoulder. The groove has a floor surface with an outer diameter less than the outer diameter of the pipe element. A bead is formed contiguous with the groove. The bead has an apex with an outer diameter greater than the outer diameter of the pipe element.
