subject: Improved convoluted flanges [print this page] The result of the analytical design for the slip-on flange can be applied to other convoluted flange designs, such as a welding neck flange or any flange where it is desired or advantageous to optimize the reduction of material in the flange or to shift the load point from a locus of the centerline of bolt holes to a locus concentrically closer to the centerline of the pipe.
