A separator device for removing particles from suspension in a fluid includes first and second fluid-carrying portions and a non-fluid-carrying spacer for linking the first and second fluid-carrying portions. Each of the fluid-carrying portions includes a socket for receiving an open end of a pipe and a connector for connection of the filter. The socket of the first fluid-carrying portion has a pipe receiving depth greater than that of the socket of the second fluid-carrying portion. The sockets of the first and second fluid-carrying portions are positioned on a common axis and facing away from each other when the fluid-carrying portions are linked by the spacer.

The flow path opening/closing portion replacement device comprises a first enclosing portion having a first opening and a shutter, and enclosing, in a state where the shutter has closed the first opening, an end portion of a converging pipe through which a fluid passes and a valve which is attached to the end portion; a second enclosing portion having a detachable member enabling the valve to be detached and a second opening which can be contiguous with the first opening and enabling removal/insertion of the detachable member, and enclosing the valve together with the first enclosing portion in a contiguous opening state in which the first opening and the second opening are contiguous, wherein, in a state where the second enclosing portion has enclosed the valve together with the first enclosing portion in the contiguous opening state, the valve can be replaced by the detachable member.

A valve and coupling for joining pipe elements has a valve body captured in a central space defined by a plurality of coupling segments attached to one another end to end. The inner surface of the valve body defines a bore. A liner on the inner surface surrounds the bore and forms a seal with a valve closing member. Circumferentially arranged projections on the segments engage and center the valve body within the central space. The liner has lobes that extend axially in opposite directions. The lobes are compressed between the segments and the pipe elements to form a fluid tight seal when connection members are tightened to draw the segments toward the central space and into engagement with the pipe elements.

Aspects of the present disclosure relate to crane systems and pump manifold systems, and related methods, for pumping operations (such as frac operations). In one or more embodiments, a pump manifold system includes a plurality of connection blocks, a plurality of conduits coupled between the plurality of connection blocks, and a crane system. The crane system includes a base, and a first crane coupled to the base and configured to extend relative to a first side of the at least one conduit. The first crane is pivotable relative to the at least one conduit.

Aspects of the present disclosure relate to connection blocks and pump manifold systems, and related methods, for pumping operations (such as frac operations). In one implementation, a connection block for disposition along a pump manifold of a pump system includes a first end hub having a first tube and a first outer shoulder extending outwardly relative to the first tube. The connection block includes a second end hub opposing the first end hub. The second end hub has a second tube and a second outer shoulder extending outwardly relative to the second tube. The connection block includes one or more faces between the first end hub and the second end hub.

A coupler for aseptically coupling and controlling fluid communication between at least two components. The coupler includes a first connector housing with an inner concave surface. A first connector extends from the top of the first connector housing and is adapted to connect to a first component. A first connector conduit extends through the first connector and into the first connector housing so as to define a fluid passageway to an inner opening on the inner surface of the first connector housing. A rotary valve is located within an inner cavity of the first connector housing and includes at least two rotary valve segments. The rotary valve segments are configured to rotate within the cavity. At least one of the rotary valve segments includes a fluid conduit extending through the at least one rotary valve segment.

Provided is a hose including a first connector assembly including a regulator assembly, a second connector assembly, and a hose assembly coupled to the first and second connector assemblies. The hose assembly includes an inner hose member having first and second ends, an outer hose member having first and second ends, a first hose connector assembly coupled to the first ends of the inner hose member and outer hose member and the first connector assembly, and a second hose connector assembly coupled to the second ends of the inner hose member and outer hose member and the second connector assembly.

A plumbing fitting for selectively allowing the passage of a fluid therethrough includes an elongate body with a first open end and a second open end, with a passageway providing for fluid communication between the first open end and the second open end, where at least one of the first open end and/or the second open end include a connection arrangement for connection with a further plumbing fitting or fixture, and a valve for selectively sealing or unsealing the passageway to allow for a flow of fluid between each of the open ends, with the valve being operable from the first open end or the second open end.

An aseptic coupling device for a tube, the device comprising: a tubular insert defining a channel and having an end segment provided with means for connecting it to the tube, the tubular insert being provided with a cantilevered rod extending axially inside the channel; and an annular body having an end segment mounted on the insert and co-operating therewith to define a housing for receiving an annular sealing element that is deformable from a first state in which it defines a flow section greater than the cross section of the rod and a second state in which it tightly surrounds the rod, and that is arranged to be taken from its first state to its second state under the effect of axial compression exerted by the insert.

A coupling assembly for coupling two tubes together.
