A washpipe seal and method includes providing a first sliding mechanical face seal between two seal elements to seal a mud conduit, and a second mechanical face seal between two additional seal elements to define a cavity within a housing of the washpipe between the first and second mechanical face seals and independently from the mud conduit, and in which, during operation, a buffer fluid can be provided.

A rotatable flanged component is adapted for assembly into a flow line of a high-pressure fluid transportation system. The rotatable flanged component comprises a body and a conduit. The body has at least two ends. The conduit extends between the ends. The rotatable component also has a flange and a union face at each of the ends. The flanges and union faces are adapted to provide a flange union between the component and other flowline components at each the body end. At least one of the flanges is a rotatable flange. The rotatable flange has a central opening and a plurality of holes. The holes are adapted to accommodate threaded connectors for loading the flange with an axial force. The flange is mounted on the body end through the central opening for rotation and for transmission of the axial force to the body end.

A portable outdoor faucet is configured for attachment with a source of water via a hose. The faucet comprises a shower nob and a sprayer head, connected in relation to a main valve, which is operable to selectively direct fluid to the shower nob and the sprayer head. A hose attachment is connected in relation to the main valve. The hose attachment for attachment of a hose originating from a water source for directing water from the water source to the valve. A clamp assembly supports the main valve in relation to an environmental surface.

The disclosure describes a rotary union that includes rotating and non-rotating machine components, each having a sealing ring, which can together form a mechanical face seal. A rotor disposed on the rotating machine component includes one or more magnets. A sensor array disposed in the housing includes a plurality of sensing elements that are integrated with a control device, a communication device, and a power storage device. The sensor array further includes a magnetic pickup coil disposed to closely overlap the outer periphery of the rotor. When the rotating machine component rotates, the magnet creates a rotating magnetic field that cooperates with the magnetic pickup coil to produce electrical power to operate the sensor array.

The invention relates to a coupling for cryogenic liquefied media, said coupling comprising a coupling socket (10) and a coupling connector (30), which can be connected thereto, each being equipped with a non-return valve (15, 40). According to the invention, the coupling socket (10) comprises a front section (11), having means for connecting to the coupling connector (30), and a rear section (12), having the non-return valve (15). According to the invention, the front section (11) is connected to the rear section (12) by means of screws (33) having predetermined breaking points, which break upon exceeding a specified tensile stress. According to the invention, the sections (11, 12) separate from each other and the non-return valves (15, 40) automatically move to the closed position.

An articulating flow line connector for connecting two sections or portions of a flow line, which may be a pressurized flow line. The connector may be configured to provide a sealed connection between the two sections or portions of the flow line, and may provide for a rotating or swiveling connection between the two sections. The articulating flow line connector may generally have a seal carrier ring arranged between two flow lines hubs. Each flow line hub may connect to an end of a flow line section. The seal carrier ring may be configured to provide both a sealing surface and at least one bearing surface. The seal carrier ring may have a sealing flange, a bearing flange, and a web portion extending between the flanges. The connector may additionally have a clamp arranged around or over the seal carrier ring and a portion of the two hubs.

A swivel includes an inner and an outer ring. The rings are coaxial and rotatable relative to one another around a central axis, and define a toroidal chamber and an axial seal annulus gap between the rings. The inner and outer rings are rotatably interconnected via a bearing structure. The swivel includes an upper bearing structure and a lower bearing structure on each side of the toroidal chamber. Each bearing structure interconnects the inner and outer rings. An upper and a lower sealing member is situated in the seal annulus gap near a respective upper and lower bearing structure. At least one of the inner and outer rings includes an upper member, a lower member and a central member. The upper and lower members are fixedly attached to the respective upper and lower bearing structures and the central member is independently displaceable relative to the upper and lower ring members.

A mechanical sealing device according to an embodiment of the present invention includes: a sealing ring (13) attached to a protrusion (11a) protruding from a housing (11); a mating ring (23) attached to an end portion of a rotary shaft (21); a welded bellows provided around the protrusion (11a) and located between the housing (11) and the sealing ring (13). The welded bellows (15) presses the sealing ring (13) in an axial direction to cause the sealing ring (13) to be in contact with the mating ring (23), thereby ensuring high pressure force, and in particular, uniform pressure force along its entire circumference, so as to achieve high liquid tightness, while maintaining the sizes in axial and radial directions small. Furthermore, the welded bellows (15) works as a sealing member of blocking a liquid leaked out through the O-ring (14), thereby achieving assured liquid tightness. Accordingly, an outside-type mechanical sealing device can be provided which has a compact size, and is capable of ensuring high liquid tightness in response to a high rotation speed and a high liquid pressure.

Embodiments described herein relate to rotary unions for use in wafer cleaning processes. The rotary union includes a process media and a supporting media that interact in a gap between a nozzle and rotary element. By regulating the supporting media pressure, a non-contact seal is created within the gap. The non-contact seal prevents or controls process media leakage in a rotary union while enabling delivery of the process media through a platen directly underneath of a wafer without the risk of additional contamination of the process media, reducing the defect to the wafer. Additionally, the non-contact seal precludes particle generation due to seal wear, caused for example in face seals, and does not leech out any additional foreign elements.
