Long-sweep swivel joints combine rotatable bearing races with extra-long-radius elbows. Their smooth bore changes flow direction while accommodating rig-up movement, vibration and alignment differences in high-pressure iron.
Technical features
2 in to 4 in nominal sizes
Extra-long-radius elbows for smoother flow
Dual- and triple-race bearing arrangements matched to load and duty
High-nitrile packing and brass-ring options
Threaded, integral wing-union or weld-preparation ends
Flame-hardened, carburized/hardened or snap-in stainless ball-race options
Styles 10, 20, 30, 40, 50, 60, 70, 80 and 100
Typical applications
Fracturing lines
Cementing and acidizing
Choke-and-kill and testing lines
Circulating-hose assemblies
High-pressure temporary piping
