Double Studded Pack off Flange, provides a double” P” or “FS” seal for sealing the casing. The double studded pickoff flange is also used as an intermediate crossover flange when a restricted area is used in the smaller diameter top groove. When a crossover is used, the top connection can be exposed to a higher pressure than the original rated working pressure. The double molded elastomer P seals are energized by injecting the high-pressure grease/plastic packing.
