Abstract
A reinforced wellhead member for use during fracing operations. The wellhead member is preloaded at a flange section by creating compressive stresses via a ring that interacts with a tightening nut on a bolt. The bolt is rigidly attached to an adapter which may also be modified to create stresses on the flange of the wellhead member. The induced stresses counter the tensile stresses experienced by the flange during fracing operations, allowing a standard wellhead member to be utilized.
