Abstract
In well installations subjected to high internal fluid pressures, hangers for long casing strings are supported independently in the upright bore of a wellhead body or other support member without requiring that the hangers be stacked one atop another or that the bore diameter be stepped to provide an upwardly exposed shoulder for each hanger. All hangers save the lowermost hanger are supported by an annular support member engaged in a groove in the wellhead body, with no load being transferred from an upper hanger to a lower hanger.
