A union is used to join mating high pressure flow line components. The union comprises an abutment, an annular gland, a seal assembly, and a plurality of threaded connectors. The abutment is between bearing surfaces on the mating components. The gland is formed by alignment of rabbets on the mating components and extends axially across and radially inward of the bearing surface. The seal assembly is carried in the gland and comprises first and second elastomeric seals on each side of a metal backup ring. The threaded connectors extend through holes in the mating components and apply axial load to the abutment to form the union.

A densitometer assembly comprises a pipe fabricated from a high-yield steel, a radioactive source, and a detector. The radioactive source is mounted on an exterior wall of the pipe and is adapted to emit gamma radiation in a defined beam. The detector is mounted on an opposing, facing exterior wall of the pipe in alignment with the gamma radiation beam and is adapted to detect gamma radiation.

Swing valves have a passage and a sleeve. The passage has a receptacle, and the sleeve is pressure fitted into the receptacle. The sleeve is adapted to conduct flow through the valve and comprises a first end, a second end, and a valve seat. The first end of the sleeve is pressure fitted into the receptacle. The second end projects out of the receptacle. The valve seat is on the face of the second sleeve end. The second sleeve end also is adapted to couple with a sleeve cap extending over and across the second sleeve end to shut off flow through the sleeve.

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 missile flow line is assembled in a frac manifold to manifold the discharge from a plurality of pumps. The missile comprises at least two junction fittings joined by a flange union to at least one spooled pipe to form a conduit. The junction fittings comprise a fitting body having a primary bore and at least two feed bores. The primary bore extends axially through the body between primary union faces adapted for connection to a flowline component by a flange union. The feed bores extend radially through the body from a feed union face to an intersection with the primary bore. The feed union faces are adapted for connection to pump discharge lines by a flange union. The intersections of the feed bores with the primary bore are offset axially from each other along the primary bore.

Frac manifold missile and fitting

Missiles for frac manifolds manifold the discharge from a plurality of pumps. The missile comprises a missile body and inlet assemblies. The missile body has a straight primary bore and a plurality of feed bores. The primary bore extends axially through the missile body. The feed bores extend radially through the missile body and define a socket. An inlet assembly is associated with each feed bore. The inlet assembly comprises a nipple and a collar. The nipple has a bore extending axially between a spigot and a union end. The nipple is connected to the collar. The spigot is received in the socket of the feed bore. The union end is adapted for connection to a flowline component. The collar comprises mating parts releasably coupled together around the missile body. The nipple is thereby releasably coupled to the missile body by coupling the collar to the missile body.

Missile for frac manifold

Missile flow lines are incorporated into frac manifolds, especially trailered or skidded frac manifolds. The missiles manifold the discharge from a plurality of pumps and comprise at least two junction fittings joined by spooled pipe. The junction fittings comprise a body having a primary bore and at least two feed bores. The intersections of the feed bores with the primary bore are offset axially from each other along the primary bore. The junction fittings are joined by flange unions to at least one spooled pipe such a that the junction fittings and spooled pipe form a conduit including the primary bores. A discharge line from a pump may be joined to each feed union face of the junction fittings by a flange union. Thus, the discharge from the pumps may be manifolded into the conduit.

Frac manifold and systems

Flowline junction fittings are assembled to missiles of frac manifolds. The fittings have a body with a primary bore, at least four secondary bores, and a tertiary bore. The bores extend from union faces adapted for connection to flowline components by a flange union. The tertiary bore intersects with the primary bore at an angle of approximately 90&#xb0;. Goat head fittings are assembled to well heads. The goat heads have a body with a primary bore and at least four secondary bores. The bores extend from union faces adapted for connection to flowline components by a flange union. The intersections between the secondary bores and the primary bore have an interior angle of substantially less than 90&#xb0;.

Missile flow lines are incorporated into frac manifolds, especially trailered or skidded frac manifolds. The missiles manifold the discharge from a plurality of pumps and comprise at least two junction fittings joined by spooled pipe. The junction fittings comprise a body having a primary bore and at least two feed bores. The intersections of the feed bores with the primary bore are offset axially from each other along the primary bore. The junction fittings are joined by flange unions to at least one spooled pipe such that the junction fittings and spooled pipe form a conduit including the primary bores. A discharge line from a pump may be joined to each feed union face of the junction fittings by a flange union. Thus, the discharge from the pumps may be manifolded into the conduit.

Flowline components are assembled into high-pressure fluid transportation systems by a flange union. The flowline component comprises a body defining a substantially cylindrical central conduit. The conduit extends between first and second flat union faces and is adapted to conduct fluids through the body. The union faces are adapted to provide a mating surface for a flange union between the component and another flowline component. Accordingly, the union faces have a plurality of holes adapted to accommodate threaded connectors for forming the flange union. The holes are arranged in a defined array extending angularly around the conduit. Importantly, the array of holes on the first union face and the array of holes on the second union face are offset angularly relative to each other by an angle &#x394;. It will be appreciated that such components may allow changes in the direction of a flow line.

Pressure relief valves may be tapped into flow lines. The pressure relief valves are normally shut and are adapted to open at a threshold pressure in the flow line. The valves comprise a body which is adapted to allow the valve to be tapped into the flow line. A passage is defined in the body. The passage provides a valve inlet and a valve outlet. The inlet is in fluid communication with the flow line. A sacrificial closure is disposed in the passage and blocks flow through the passage. The closure is exposed to fluid pressure in the flow line. The valve also comprises means for compromising the sacrificial closure in response to detection of the threshold pressure in the flow line. The integrity of the closure will be compromised such that fluid from the flow line may flow through the passage and out the valve outlet.

Pressure relief valve

Pressure relief valves may be tapped into high-pressure flow lines. The pressure relief valve is normally shut and is adapted to open at a threshold fluid pressure. It comprises a body, a passage, a valve seat, a ball, and a linear actuator. The passage is defined in the body and has a valve inlet and a valve outlet. The valve seat is in the passage. The ball is adapted to engage the valve seat to block flow through the passage. The linear actuator is mounted for linear movement in response to detection of the threshold pressure a from a normally extended position to a retracted position. In the extended position the ball engages the valve seat to close the passage, thereby shutting the valve. In the retracted position the ball can be flushed out of the valve by fluid flowing through the passage, thereby opening the valve.
