WPF Packoff Flange WPF packoff flanges are designed to fit over wellbore casing and provide an auxiliary seal. With the flange in place, a jump in pressure rating can be achieved in a minimum of space. The flange allows the operator to test between the flange and the annular seal in the section above or below. WPF is available in all nominal flange and casing sizes. Flanges with a working pressure rating of 2,000 and 3,000 psi are provided standard with pressure energized O-ring seals . Flanges with pressure ratings of 5,000 to 15,000 psi are provided standard with two integral P seals.

WXF Crossover Flange WXF crossover flanges are used where a change in flange size or a decrease in flange pressure rating is required with no need for an annulus pressure seal. Flanges are typically double studded to minimize wellhead stack height and reduce cost . If required, the operator may specify a height for the flange. The units may also be provide to a specified height with through bolted flanges to achieve required spacing. WXF is available in all nominal flange size and pressure ratings. |

WCF Companion Flange WCF companion flanges are available in nominal flange sizes from 2 1/16" to 5 1/8" and pressure ratings to 5,000 psi. Threaded connections are either line pipe or upset tubing of the same nominal size as the flange. Since pressure ratings are limited by the rated working pressure of the threaded connection, other thread types can be furnished on request. |
