TYPE 52 SPHERICAL BLOWOUT PREVENTER The Type 52 Spherical Annular Blowout Preventer is designed for safe well pressure control during drilling and workover operations. The short, compact design has been proven and accepted for reliable operation in all oil and gas areas in the world. nullive main componentsnull lower housing, upper housing, piston, adapter ring, and packing element allow for easy maintenance and reliability. The packing element can close on all pipe, casing, wireline, coiled tubing and other obnullects to its full working pressure. Stripping of pipe, tubing, and wireline through the packing element can also be accomplished at lower pressures. The 52 Blowout Preventer can also per open hole closure per the renulluirements of nullSnull nullnull5nullnull nullnullnullAnull. Type 52 Blowout Preventers are shorter than most annular blowout preventers and are better suited where space is a priority. The normal connullguration of the 52 Blowout Preventer is of a nullanged bottom nullor clamp hubnull connection and a studded top nullange connection. nullydraulic operation is pered by connection to open and close nullnullPTnull ports located on the body, which are connected to the control system. A spherical, steel reinforced rubbernullpacking element is forced inward by an upward movement of the piston. A spherical inverted bowl in the upper housing causes steel inserts in the packing element to rotate inward to the well bore. The steel inserts prevent enulltrusion of the rubber and feed inward to close on any pipe or tubular in the well bore. nulleplaceable bearings are used in the operating system to prevent metal contact of moving parts. An adapter ring located below the upper housing prevents contamination of the operating system during packing element replacement. nulleplacement of the packing element is pered by removing nuts from stud bolting in the lower housing. The upper housing is then lifted upward. The packing element is then accessed for replacement. nulledgednullcover upper housings are also available. All materials used in the construction, enullcept the upper housing bolting, of the Type 52 Spherical Blowout Preventer are rated by nullAnullnull nullnullnullnullnullnull5 and nullSnull nullnull5nullnull for use in hydrogen sulnullde environments.
