  • Patent number: 5135266
    Abstract: A method and an apparatus for attaching an upper wellhead housing to casing employs a combination slip and seal assembly. An annular metal slip member is supported by a lower wellhead housing. The slip member has a conical section with an annular external seal. The interior of the slip member contains circumferential teeth. When the upper wellhead housing is placed over the slip member and clamped to the lower wellhead housing, it wedges the slip member radially inward. The internal teeth will embed against the casing to grip the casing. The external seal seals against the upper wellhead housing bore conical surface. A retaining ring engages the slip member and locates between mating shoulders of the upper and lower housings to limit downward travel of the slip member.
