A self-restrained pipe joint system and method of assembly to connect two lengths of pipe in a mechanical joint, which maximizes the advantages of both restrained push-on joints as well as mechanical joints, as are known commonly in the art. The invention has application to long-run pipe lengths as well as to appurtenances, including fittings and connections. The gasket contains locking members that act to restrain separation upon the instance of any force tending to separate the connected pipe lengths.

1. A method of assembling a self-restrained pipe joint system, comprising the steps of: disposing an elastomeric restraining gasket within an opening of a female piping member;affixing a retaining flange to the end of the female piping member, wherein affixing the retaining flange to the end of the female piping member includes engaging the retaining flange with the gasket and the female piping member, and wherein engaging the retaining flange with the gasket includes accommodating a flanged portion of the gasket in a lower counterbore of the retaining flange; andinserting a spigot end of a male piping member of the pipe joint system into the female piping member of the pipe joint system through a circular opening in the retaining flange. 2. The method of claim 1, wherein disposing the gasket within the opening of the female piping member includes engaging a supporting portion of a restraining segment of the gasket with a surface of the female piping member. 3. The method of claim 1, wherein disposing the gasket within the opening of the female piping member includes disposing the gasket within a retaining groove in the opening of the female piping member. 4. The method of claim 3, wherein disposing the gasket within the opening of the female piping member includes engaging a retaining wall of the retaining groove with an outer sealing surface of the gasket. 5. The method of claim 4, wherein engaging the retaining wall of the retaining groove with the outer sealing surface of the gasket forms a fluid tight seal. 6. The method of claim 1, wherein disposing the gasket within the opening of the female piping member includes securing the gasket to the female piping member at the flanged portion of the gasket. 7. The method of claim 1, wherein engaging the retaining flange with the gasket includes securing the gasket in a retaining counterbore in the retaining flange. 8. The method of claim 7, wherein securing the gasket in the retaining counterbore in the retaining flange includes securing a retaining portion of the gasket in the retaining counterbore in the retaining flange. 9. The method of claim 1, wherein engaging the retaining flange with the female piping member includes engaging a lower surface of the retaining flange with an outer surface of a flange of the female piping member. 10. The method of claim 1, wherein inserting the spigot end of the male piping member into the female piping member includes stopping the spigot end of the male piping member against a shoulder region of the female piping member. 11. The method of claim 1, wherein inserting the spigot end of the male piping member into the female piping member includes engaging a restraining segment of the gasket with the male piping member. 12. The method of claim 1, wherein inserting the spigot end of the male piping member into the female piping member includes forming a fluid tight seal. 13. The method of claim 12, wherein the fluid tight seal is formed by engaging an inner gasket surface with an outer surface of the male piping member. 14. The method of claim 12, wherein the fluid tight seal is formed by rotating a restraining segment of the gasket with the male piping member. 15. A method of assembling a self-restrained pipe joint system, comprising the steps of: disposing a retaining portion of an elastomeric restraining gasket into a retaining counterbore of a retaining flange;inserting a sealing portion of the restraining gasket, assembled with the retaining flange, within a sealing cavity of a female piping member, wherein affixing the retaining flange to the female piping member includes engaging the retaining flange with the restraining gasket and the female piping member, and wherein engaging the retaining flange with the restraining gasket includes accommodating a flanged portion of the restraining gasket in a lower counterbore of the retaining flange;affixing the retaining flange to the female piping member; andinserting a spigot end of a male piping member of the pipe joint system into the female piping member of the pipe joint system through a circular opening in the retaining flange. 16. The method of claim 15, wherein inserting the spigot end of the male piping member into the female piping member includes engaging a restraining segment of the gasket with the male piping member. 17. The method of claim 15, wherein inserting the spigot end of the male piping member into the female piping member includes forming a fluid tight seal. 18. The method of claim 17, wherein the fluid tight seal is formed by rotating the restraining segment of the gasket with the male piping member. 19. A method of assembling a self-restrained pipe joint system, comprising the steps of: disposing a restraining elastomeric gasket within an opening of a female piping member;affixing a retaining flange to the end of the female piping member, wherein affixing the retaining flange to the end of the female piping member includes engaging the retaining flange with the gasket and the female piping member, and wherein engaging the retaining flange with the gasket includes securing the gasket in a retaining counterbore in the retaining flange; andinserting a spigot end of a male piping member of the pipe joint system into the female piping member of the pipe joint system through a circular opening in the retaining flange. 20. The method of claim 19, wherein securing the gasket in the retaining counterbore in the retaining flange includes securing a retaining portion of the gasket in the retaining counterbore in the retaining flange. 21. A method of assembling a self-restrained pipe joint system, comprising the steps of: disposing a retaining portion of an elastomeric restraining gasket into a retaining counterbore of a retaining flange;inserting a sealing portion of the restraining gasket, assembled with the retaining flange, within a sealing cavity of a female piping member;affixing the retaining flange to the female piping member, wherein affixing the retaining flange to the female piping member includes engaging the retaining flange with the restraining gasket and the female piping member, and wherein engaging the retaining flange with the restraining gasket includes securing the restraining gasket in a retaining counterbore in the retaining flange; andinserting a spigot end of a male piping member of the pipe joint system into the female piping member of the pipe joint system through a circular opening in the retaining flange. 22. The method of claim 21, wherein securing the restraining gasket in the retaining counterbore in the retaining flange includes securing a retaining portion of the restraining gasket in the retaining counterbore in the retaining flange.
