Abstract:
The disclosure relates to a gripping apparatus, for use in connecting to a pipe wherein the pipe defines an inside radius, the apparatus having at least one discrete gripping device mounted on a body, wherein the body is a wedge cone; an outer surface on each of the at least one discrete gripping device, wherein the outer surface has a transition surface defined by a means for reducing any sharp transition point; a coating on the outer surface; a collective actuation-retraction mechanism connected to the wedge cone and to each of the at least one discrete gripping device; and a collective extension-retractable mechanism connected to each of at least one discrete gripping device. The disclosure further relates to an alternative exemplary embodiment wherein the gripping apparatus further includes a spring, wherein the spring pre-biases each of the at least one discrete gripping device beyond the inside radius of the pipe to instantly grip the inside radius.
