ABSTRACT:
A metal support ring is located between a housing and a wellhead for reducing bending movement of the wellhead relative to the housing. The support ring has a plurality of circumferentially extending ribs for engaging the bore of the housing. The ribs are parallel to and vertically spaced apart from each other. Each rib protrudes outwardly from the wellhead a distance greater than the inner diameter of the housing. This causes the ribs to deflect in an interference fit when the wellhead is inserted into the housing.
