move axially relative to the mandrel 301 fig6 and 6a show a section view of a frac plug having a non metallic sealing system of the present invention in a set position within a wellbore referring to both fig6 and 6a the force asserted against the setting ring 340 transmits force to the slips 310 315 and cones 320 325 the slips 310 315 move up and across the tapered surface of the cones 320 325 and contact an inner surface of a surrounding tubular 700 the axial and radial forces applied to slips 310 315 causes the recessed grooves to fracture into equal segments permitting the serrations or teeth of the slips 310 315 to firmly engage the inner surface of the surrounding tubular axial movement of the cones 320 325 transfers force to the support rings 240 245 as explained above the opposing forces cause the support rings 240 245 to move across the tapered first section of the expansion rings 230 235 as the support rings 240 245 move axially the first section of the support rings 240 245 expands radially from the mandrel 250 while the wedges 248 hinge radially toward the surrounding tubular at a pre determined force the wedges 248 break away or separate from the first section 242 of the support rings 240 245 the wedges 248 then extend radially outward to engage the surrounding tubular 700 the compressive force causes the expansion rings 230 235 to flow and.
