Rough Casing Metal Seal (RCS)
The Rough Casing Metal Seal (RCS) is a secondary seal that provides a gas-tight seal against non-machined casing surfaces. The RCS is easily energized by making up the flange and is externally testable in the operating direction to the full working pressure. The adjustment/support rings rest on the entry taper of standard casing spools with the preferred W2 and T bowls. The RCS can also be provided to engage other bowl profiles, packoff support flanges or even non-WGPC equipment. The RCS is rated for applications up to 20,000 psi.
