摘要： A rotatable mount for a blowout preventer bonnet (14). A slide mounting bar (70) is slidably couples to a body (12) of the blowout preventer. The slide mounting bar (70) is adapted to move along an axis of a side opening (59) of the body of the blowout preventer. A swivel (74) is coupled to the mounting bar and to the bonnet. The swivel is adapted to enable rotation of the bonnet when the bonnet is disengaged from the body of the blowout preventer.

摘要： A rotating diverter (108) for isolating fluid in a well (30) from other fluid above the well (30) is provided. The rotating diverter (108) includes a housing body (162) which has a bore (168) running through it. A retrievable spindle assembly (178) which includes a spindle (178) and a bearing assembly (184) is disposed in the bore (168). The bearing assembly (184) supports the spindle (178) for rotation. The spindle (178) is adapted to receive and seal around a tubular member, and rotation of the tubular member rotates the spindle (178) within the bore (168). A lock member (176) is disposed in the housing body (162) to secure the retrievable spindle assembly (178) to the housing body (162).

摘要： A threaded pipe connection is disclosed for connecting two joints of pipe having externally threaded pin members (10, 12), one pin member (10) having external right-hand threads (14) and the other pin member (12) having left-hand threads (16). An internally threaded coupling (18) having right and left-hand threads (20, 22) that mates with the threads (14, 16) on the pin members (10, 12). An internal pressure seal ring (23) is positioned to provide a seal between the ends of the pin members (10, 12). A plurality of mating lugs (24) and grooves (26) on the ends of the pin members (10, 12) hold the pins from relative rotation when the connection is being made up. A metal-to-metal seal located between each pin member (10, 12) and the coupling (18) adjacent each end of the coupling (18) isolates the threads of the connection from the ambient environment thus sealing off the pipe annulus from external pressure due to hydrostatic head. Indicia such as engaging surfaces (24a, 26a) or aligned scribe lines on the pin members (10, 12) ensure that the sealing surfaces (28, 29, 30, 31) on the coupling (18) and the pin members (10, 12) that form the external seals are positioned to properly engage and form seals when the connection is made up.
