Abstract

A gripping apparatus for use in gripping a pipe, for holding forces, or restraining relative movement. The pipe defines an inside radius. The gripping apparatus has an outer surface where the outer surface defines a transition surface or a curve. In certain embodiments the transition surface or curve has a radius less than or equal to the inside radius of the pipe.
