12. A method of installing a wellhead assembly, the method comprising:
positioning a hollow wellhead housing body with respect to an additional hollow body such that an end of the hollow wellhead housing body is received by an end of the additional hollow body and an axial bore extends through the hollow wellhead housing body and the additional hollow body;
tightening a clamp such that the clamp applies a radially inward force to securely connect the hollow wellhead housing body to the additional hollow body, the clamp including a compression ring positioned outside of the hollow wellhead housing body;
positioning a wellhead hanger in the axial bore; and
with the wellhead hanger positioned in the axial bore, further tightening the clamp such that the clamp applies an increased radially inward force that elastically deforms the additional hollow body and causes the additional hollow body to securely grip the wellhead hanger.
