Abstract
A multi-component tubular coupling is provided for wellhead assemblies. In one embodiment, the multi-component tubular coupling may include a first tubular member, a landing ring, and a second tubular member. The second tubular member may include internal threads, lock screws, or any combination thereof to couple to a wellhead component. In another embodiment, the multi-component tubular coupling may only include the first tubular member and the landing ring. In such an embodiment, a wellhead component may be secured to the coupling via lock screws.
Claims22
A system, comprising:
- a coupling for a mineral extraction system, wherein the coupling comprises:
- a landing ring comprising a landing portion and a first protruding portion extending radially relative to the landing portion;
- a first tubular comprising a first tubular portion coupled to the landing ring;
- and
- a second tubular comprising a second tubular portion and a second protruding portion extending radially relative to the second tubular portion, wherein a first abutment surface of the first protruding portion is configured to radially overlap with a second abutment surface of the second protruding portion and a third abutment surface of the first tubular to block axial movement between the landing ring, the first tubular, and the second tubular.
