Abstract: For protecting a tubular or a component attached to the tubular, two sections of the expandable tubular are formed into two complete centralizing rings or two partial centralizing rings having a larger outer diameter than the remainder of the expandable tubular. A sleeve is placed over a box thread of the tubular or over the component. An adhesive fully covers the space between the inside diameter of the sleeve and the outside diameter of the box thread or component. The sleeve remains in place when the tubular is placed down hole.
