Abstract
A method for inhibiting separation of joined pipes including providing within a pipe bell a gasket including rigid segments, each segment having bell teeth configured for engaging the bell and a spigot tooth configured for engaging a pipe spigot seated in the bell. Upon pressurization and over-pressurization of the joint, resulting axial forces exerted on the joint, which can cause pipes to separate, are countered by wedging the segments between the bell and the spigot and rotating each segment so that the thrust forces are directed radially. To prevent radially-directed thrust forces from damaging the joint through over-rotation of the segments, the bell teeth and the spigot tooth are adapted and arranged to maintain the thrust forces load path carried by each segment within a desired angular range relative to the spigot by transferring the load path between adjacent bell teeth whereby the effective length of each segment is increased.
