ABSTRACT:
A threadless interconnection system for sections of pipe as provided by a male/female interconnection in which the male member and female members have mating tapered surfaces providing both the camming action for inset snap rings that engage concurrently upon assembly of the interconnection. The tapered section includes angles which assure that snap rings are precentered within tolerances before being gradually opened during the assembly process, while also providing a metal-to-metal seal after assembly. Sealing is facilitated by composite seals that include O-rings arranged with compatible actuator and backup rings so as to avoid destruction of the O-ring geometry because of bending, flexure and torsional forces.
