ABSTRACT:
A process is disclosed for forming pipe fitting components, in particular for the manufacture of three-piece unions made of steel and formed by cold deformation operations, by subjecting lengths of tubes cut to size to stresses substantially applied in an axial direction by the use of dies designed for acting upon at least a portion of the wall of the connecting pieces to be formed. The pipe fitting components obtained by the above process are made of steel and have peculiar features as to their size and shape.
