Zusammenfassung:	A swivel assembly for oilfield operations, the swivel assembly including a first pipe section having a first end fitting and a second pipe section having a second end fitting corresponding to and receiving the first end fitting, each of the first and second end fittings having an inner surface and an outer surface. The swivel assembly further includes a swivel joint rotatably securing, via the corresponding first and second end fittings, the first and second pipe sections together along a central axis to define a fluid passageway therethrough. At least a portion of one of the first pipe section and the second pipe section is formed of a corrosion-resistant material having a first hardness and at least a portion of the swivel joint is formed having a second hardness different from the first hardness.
