Abstract: A pipe assembly includes a flexible pipe segment and at least one end fitting. The at least one end fitting includes an end casing coupled to the flexible pipe segment and a seal housing removably coupled to the end casing. The end casing defines a seal housing-receiving bore extending longitudinally through the end casing, and the seal housing is positioned within the seal housing-receiving bore. The seal housing defines at least one seal bore extending from an axially distal surface of the seal housing, and one or more sealing elements are seated in a respective one of the at least one seal bore. The end casing is couplable to a counterpart fitting, and the seal housing and/or the one or more sealing elements are configured to define a sealing interface with the counterpart fitting.

Abstract: Embodiments relate to a check valve and methods of making a check valve that include a valve body having an inlet end, an outlet end, a flow bore that extends between the inlet and outlet ends, a cavity which intersects the flow bore, and an opening which is connected to the cavity.

Abstract: A manifold assembly for connecting a plurality of pumping units to a wellhead includes at least one main line which is connectable to the wellhead and includes a plurality of discharge connectors, and a plurality of articulating arm assemblies which are each connected to a corresponding discharge connector. Each arm assembly comprises a connector member which includes at least an inlet port, an outlet port and a third port that is located generally opposite the outlet port and is closed by a removable plug member, an articulating conduit assembly which comprises a first end that is connected to the inlet port and a second end that is connectable to a corresponding one of the plurality of pumping units, and a riser swivel which is connected between the outlet port and the discharge connector. In use of the manifold assembly, each arm assembly is connected to a corresponding pumping unit and the main line is connected to the wellhead to thereby connect the pumping units to the wellhead.

Abstract: A manifold trailer comprises at least one main line having a plurality of discharge connectors and a plurality of articulating arm assemblies which are each connected to a corresponding discharge connector. Each arm assembly comprises a connector member which includes an inlet port, an outlet port and a third port which is located generally opposite the outlet port and is closed by a removable plug member. Each arm assembly also includes an articulating conduit assembly which comprises a first end that is connected to the inlet port and a riser swivel which is connected to the outlet port. During deployment of the arm assembly, a second end of the conduit assembly is connectable to a pumping unit to thereby fluidly connect the pumping unit to the main line.

Abstract: A turbine flow meter comprises a flow pipe which includes an axial through bore and a meter cartridge which is positioned in the through bore. The meter cartridge includes a tubular cartridge housing through which a fluid to be measured is directed and a rotor which is rotatably supported in the cartridge housing. The cartridge housing is slidably received in a first portion of the through bore and comprises an outer diameter which is less than the diameter of that portion of the through bore. The meter cartridge is retained in the through bore by a retainer, which in turn is retained in the through bore by a ring seal.
