Abstract
The present disclosure relates generally to downhole tubulars, and more particularly, to tubular expanders for downhole tubulars that have a detachable expansion ring, which can be detached from the tubular expander in the event that full expansion cannot be achieved or the tubular expander should get stuck in the downhole tubular being expanded. The detachable expansion ring may be attached to an end of an expansion cone that is disposed within a main body of the tubular expander. Tubing hangers are one exemplary downhole tubular device which can be expanded using the tubular expander in accordance with the present invention.
