Guiberson

Blowout Preventers (Type 'T' and Type 'G')

The type ‘T’ blowout preventer is the industry’s first high temperature blowout control unit. Rated at 550°F and 1,500 psi working pressure, the type ‘T’ was developed specifically for use on steam injection, downhole heater, and high-temperature production installations. Designed for 3-1/2” tubing, the preventer is available with blank rams or to pack off all sizes of polished rods, macaroni pipe, or wirelines. All metal backed rams are used with a newly developed sealing element for additional safety in handling high-temperature fluids. Pressure around the rams is equalized for easy operation under high pressure. The Type ‘T’ series rams can also be replaced with low cost Type ‘G’ tubing blowout preventer rams for running or pulling sucker rods and macaroni tubing when the well is chilled.

Guiberson Tubing Blowout Preventers are designed to contain well pressure when swabbing or handling sucker rods or small diameter tubing. In swabbing applications the preventer can supplement the lubricator, allowing removal of the oil saver. A single unit may be employed above the master valve, or two preventers may be stacked and the lower one fitted with blind rams in place of the master valve. The Tubing Blowout Preventer uses a special rubber packing element, molded integrally to a steel slide for maximum safety and freedom from leakage. The chamfered tops of the rubber elements allow them to deform under pressure without fouling the housing, ensuring easy retractability. The drive screws of the preventer are located at the center of the sealing surface of the rubber, off-center of the rams, for maximum positive seal against the sinker bar, tubing, or rod. An O-ring seal around the rams prevents pressure bypass in any position.
