Abstract
A pipe seal assembly includes a stiffener having an axis, an inner diameter (ID) and an outer diameter (OD). The seal assembly also includes an elastomer that is coupled to and extending though the stiffener, such that the elastomer is located on both the ID and the OD of the stiffener. A method of manufacturing a tubular member includes forming the tubular member with a female end; locating a seal assembly having an extension inside the female end, pressing the seal assembly into the female end to form a seal groove, belling the tubular member using the seal assembly to form a belled shape, and pressing the extension into the interior of the female end to form a spline groove inside the female end adjacent the seal groove; and then sacrificially removing the extension, but leaving the seal assembly to form a final assembly.
