  • Bending tool and method for pipes of differing widths
    Patent number: 6446483
    Abstract: A pipe bending tool is formed from a body and a pipe engaging hook. The body features a curved and convex base in which a longitudinal channel is formed. The channel features a first section, characterized by planar and preferably parallel side walls, and a deeper and adjacent second section, characterized by planar side walls, which preferably taper. The side walls of the second section preferably converge at a 90° angle to form a V-shaped channel base. This channel design permits pipes of more than one diameter to be bent in the same tool.
