  • Flaring die with stress relief features
    Patent number: 6497132
    Abstract: A pipe flaring die has a central opening with a profile configured to reduce stress concentrations at the base of the flared portion of the pipe. The profile includes an annular relief area intermediate an annular gripping surface and an annular beveled portion which defines the angle of the flared portion. The relief area provides a longer transition distance for the formation of the flared portion which results in a reduced residual stress concentration created at the base of the flared portion during the forming process.
