摘要： Frac pumps have a fluid end and a fluid end block. The fluid end block has a plunger cylinder having a primary axis, a suction bore having a primary axis, a discharge bore, and a pump chamber. The pump chamber is defined by the intersection of the plunger cylinder, the suction bore, and the discharge bore. The fluid end block has a cylindrical portion extending along the primary axis of the suction bore. The cylindrical portion has a diameter greater than the diameter of the plunger cylinder. The pump chamber also has a ridge that extends radially inward from the walls of the pump chamber in a plane normal to the suction bore primary axis.

摘要： Dual path control fittings have a fitting body and a cylindrical plunger. The fitting body has a cylindrical bore, a first conduit, and a second conduit. The cylindrical bore provides a first inlet and an opening. The first conduit provides a second inlet. The second conduit provides an outlet. The cylindrical plunger is mounted for reciprocation in the bore and has a first conduit and a second conduit. The first conduit extends from one end of the plunger to a port on the circumference of the plunger. The second conduit extends transversely across the plunger. The plunger has a first position in which the port is aligned with the second fitting body conduit to provide a first path and a second position in which the plunger second conduit is aligned with the fitting body first and second conduits to provide a second path.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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°. 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°.

摘要： 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 Δ. It will be appreciated that such components may allow changes in the direction of a flow line.
