Rotary assembly formed of corrosion resistant material

A rotating assembly for oilfield operations includes a first pipe section having a first end fitting; and a second conduit section having a second end fitting corresponding to and receiving the first end fitting, each of the first end fitting and the second end fitting having an inner surface and an outer surface. The rotary assembly further includes a rotary joint rotatably securing the first conduit section and the second conduit section together along the central axis via respective first and second end joints to define a fluid passage 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 rotary joint is formed to have a second hardness different than the first hardness. 一种用于油田作业的旋转组件，包括第一管道段，其具有第一端接头；和第二管道段，其具有对应于并且接收第一端接头的第二端接头，第一端接头和第二端接头中的每一个具有内表面和外表面。旋转组件进一步包括旋转接头，其经由相应的第一端接头和第二端接头将第一管道段和第二管道段沿中心轴线可旋转地固定在一起，以限定通过其中的流体通道。第一管道段和第二管道段中的一个的至少一部分由具有第一硬度的耐腐蚀材料形成，并且旋转接头的至
