Provided are pipe systems and methods for assembling the same. A pipe system includes two pipes, each having an axis, an exterior surface, a retainer groove formed in the exterior surface, and a sheath mounted to a respective pipe such that the sheath at least partially covers the retainer groove prior to assembly. A retainer is also located in the each retainer groove, disposed radially beneath the sheath relative to the axis, prior to assembly. The system further includes a coupling having a bell configured to receive each of the two pipes. Each bell may have a retainer groove formed in an inner surface thereof and the bell configured to receive at least a portion of a respective retainer after assembly of the pipe system. When assembled, the sheaths are configured to uncover the retainer grooves such that the retainers expand into the retainer grooves of the coupling inner surface.
