Abstract
Generally, the present disclosure is directed to metal-to-metal sealing systems and methods for use with the various pressure-retaining components, and in particular to pressure-retaining components that may be used in mudline suspension systems. In one illustrative embodiment, a system is disclosed that includes a first pressure-retaining component having an outside face, the outside face including first and second metal sealing surfaces proximate an end of the first pressure-retaining component, wherein the second metal sealing surface is positioned along the outside face between the first metal sealing surface and the end of the first pressure-retaining component. The system further includes, among other things, a second pressure-retaining component having an inside face, the inside face of the second pressure-retaining component including a third metal sealing surface that is adapted to sealingly engage at least the first metal sealing surface.
