Abstract: An embodiment of a manifold of a hydraulic fracturing system includes a flow cross junction including an inlet flow bore. In addition, the manifold includes a coupling adapter including an external shoulder and a connection device. The connection device is to connect to an output of a pump of the hydraulic fracturing system, and the coupling adapter is removably inserted within the inlet flow bore such that the connection device is positioned outside of the inlet flow bore. Further, the manifold includes a retainer ring connected to the flow cross junction and compressed against the external shoulder.

Abstract: A coupling for forming a fluid-tight connection between a first device and a second device includes a male connection member having a central axis and a radially outer surface. In addition, the coupling includes a female connection member having a central axis coaxially aligned with the central axis of the male connection member, a radially inner surface, and a radially outer surface. The female connection member includes a plurality of circumferentially-spaced holes extending radially from the radially outer surface of the female connection member to the radially inner surface of the female connection member. The male connection member is slidingly disposed in the female connection member. Further, the coupling includes a locking assembly configured to secure the female connection member to the male connection member. The locking assembly includes an annular locking ring disposed about the female connection member and the male connection member.

Abstract: A fluid transfer assembly includes a first wellbore casing positioned above-ground. The first wellbore casing is configured to receive fluid from a fluid supply system and to provide the fluid to a well assembly. The fluid transfer assembly also includes a second wellbore casing positioned above-ground. The second wellbore casing is configured to receive the fluid from the fluid supply system and to provide the fluid to the well assembly. In addition, the fluid transfer assembly includes a connection assembly coupling the first wellbore casing and the second wellbore casing. The first wellbore casing and the second wellbore casing are configured to be disposed within a wellbore to facilitate fluid flow through the wellbore.

Abstract: A check valve includes a housing having an upstream end and a downstream end. The housing includes a throughbore extending from the upstream end to the downstream end, an outer surface extending from the upstream end to the downstream end, and an access port extending from the outer surface to the throughbore. The access port includes an internal annular shoulder and one or more recesses extending into the internal annular shoulder. In addition, the check valve includes a valve seat disposed in the throughbore of the housing. Further, the check valve includes a check valve assembly at least partially disposed in the access port. The check valve assembly includes a flapper extending into the throughbore and configured to pivot relative to the valve seat between an open position spaced apart from the valve seat and a closed position engaging the valve seat.

Abstract: Embodiments of a method include connecting an inner end of a base of a fluid coupling assembly to an outer surface of a manifold of a hydraulic fracturing system. The base includes an outer end opposite the inner end and a through-passage extending from the outer end to the inner end. In addition, the method includes inserting a coupling adapter into the through-passage from the outer end to compress the coupling adapter into the through-passage and to position a connection device of the coupling adapter outside of the through-passage at the outer end.
