ABSTRACT:
A pipe hanger for supporting and sealing a tubular conduit in a producing well. The initial application of the tubular conduit weight to the hanger automatically actuates the seal and both sets of pipe gripping members. The upper set of pipe gripping slips initiates support of the tubular conduit and actuation of the seal and lower pipe gripping members. The lower pipe gripping members are moved radially inwardly by deformation of a resilient annular ring that is then contained within an enclosed chamber to prevent inadvertent release of the lower pipe gripping members.
