Abstract: 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.

Valve assemblies comprise the pivot valves and flapper valves and have an open condition, a check condition, and a shut-off condition.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
