Abstract
A system that includes a wellhead. The wellhead defines a bore. A hanger system is positioned within the wellhead. The hanger system includes a piston angled relative to a longitudinal axis of the bore. A first spring biases the piston in a first direction. The piston contacts a slip segment to couple the slip segment to a casing string.
