A 1 0 surface portion of the groove adjacent to the is angled surface portion oriented perpendicu- lar to the longitudinal axis. A mechanical coup- ling has keys that engage the groove. projecting Nalaw. The keys have mating surfaces that contact PRIOR ART ke. both the and angled perpendicular surface por- SI tions of the groove. When the pipe element and coupling are used in combination to form a 16 1 pipe joint, axial load on the pipe, resisted by is between the mechanical coupling, shared the perpendicular and angled surface portions which results in a pipe joint that can withstand higher internal pressure than if the axial load were borne by the perpendicular surface por- 1-1 .4t tion alone.
