Abstract:

A method for forming a conduit with a radial flange for forming part of a beaded coupling by: positioning a conduit blank in a forming die, wherein the forming die defines a radially extending recess; inserting a forming post in the conduit blank to define an annular space therebetween; inserting a flexible material in the annular space between the post and the conduit; placing a sleeve in a bearing relationship with the flexible material; compressing the flexible material between the post and the sleeve to force the flexible material against the conduit to expand the conduit outward into engagement with the radially extending recess in the forming die to form an annular flange; and releasing compression on the flexible material.

Abstract:

A spherical decoupler conduit for connecting misaligned components, and a method for making the same, where the spherical decoupler includes an inlet connection with a first spherical portion; an outer slider with a second spherical portion for pivotably mating with the first spherical portion and a tubular portion; an inner slider having a tubular portion in a telescoping relationship with the tubular portion of the outer slider and a third spherical portion; and an outlet connection with a fourth spherical portion for pivotably mating with the third spherical portion.
