Abstract
A system to provide at least two circumferential metal to metal seals between coaxial tubulars. Where a first tubular includes a circumferential shoulder having a circumferential first metal seal and a circumferential second metal seal. A second tubular has a circumferential shoulder that matches and abuts the first tubular circumferential shoulder. Each metal seal is of a material having a higher yield strength than the second tubular shoulder such that the first metal seal and the second metal seal will penetrate the material of the second tubular shoulder thereby providing a seal. Additionally a test port is provided from the exterior of the exterior tubular to a point on either the first or second tubular between the first and second metal seals.
Claims8
A metal to metal seal comprising;
- a first tubular having a circumferential first shoulder,
- a second tubular having a circumferential second shoulder,
- wherein the circumferential second shoulder is adjacent to and in opposition to the first tubular circumferential first shoulder, and
- the first tubular circumferential first shoulder having a first circumferential protrusion and a radially offset second circumferential protrusion.
A metal to metal seal comprising;
- a first tubular having a circumferential first shoulder,
- a second tubular having a circumferential second shoulder,
- wherein the circumferential second shoulder is adjacent to and in opposition to the first tubular circumferential first shoulder,
- the first tubular circumferential first shoulder having a first circumferential protrusion and a radially offset second circumferential protrusion,
- the first tubular further providing a fluid pathway from an exterior of the first tubular to a circumferentially open area bounded by the first tubular circumferential first shoulder, the second tubular circumferential second shoulder, the first tubular circumferential first protrusion, and the second tubular circumferential second protrusion.
