DC casing hanger are a standard wrap-around slip type for use in straight profile DC casing heads. Hanger assemblies are preassembled and supported by heavy duty hinge mechanisms which allow hangers to be attached and lowered through the BOP. Standard sizes are available for nominal flanges to 21 1/4" and for casing from 4 1/2" to 16".

The DC-2 casing hanger is designed for critical service and deep well completions where high casing weights place an unacceptable strain on conventional slip mechanisms. The integral sealing element is automatically energized with release of the casing weight. A tooth profile on the back of tapered slip elements help restrict radial loading and increase ultimate capacity.
