1. A system, comprising:
a well tool sized for placement along a well string, the well tool comprising:
a tubing;
an expandable metal tubular coupled to the tubing with connection rings, the expandable metal tubular being plastically deformable in a radially outward direction when sufficient pressure is applied to an interior of the expandable metal tubular through one or more ports formed radially through the tubing to thus expand the expandable metal tubular;
the tubing extends linearly through the expandable metal tubular such that the expandable metal tubular is positioned concentrically about the tubing; and
an anchoring ring disposed circumferentially about the expandable metal tubular, the anchoring ring having a weak point which breaks during expansion of the expandable metal tubular such that the anchoring ring is able to move radially outward without being elongated, wherein the anchoring ring comprises a plurality of notches located along an interior of the anchoring ring, such that a radial thickness of the anchoring ring is greater between adjacent notches than at each notch, and the anchoring ring remains intact at the plurality of notches following expansion of the expandable metal tubular into anchoring engagement with a surrounding surface.
