ABSTRACT:
A pressure resistant system for joining concrete pipes in an end to end relationship is disclosed. The first pipe terminates in a bell end and the second pipe terminates in a spigot end with the spigot end surrounded by a seal member and the inner surface of the bell also surrounded by a seal member. Each seal member has internal ribs which extend into and are embedded in the concrete pipe. The spigot end sealing ring includes an internal flap extending substantially perpendicular thereto across an internal offset face of the spigot and a lip extending across a portion of the end face. A rib of reduced length is disposed adjacent the lip and midway between the lip and the flap. In one embodiment the spigot and sealing ring defines a concave groove for receiving an O-ring seal, and in another embodiment the concave groove is replaced by an integral convex seal portion.
