1 Our swivel joints, with integral ball bearing, are manufactured on the basis of technologies
from FMC, USA.
2 Various models of swivel joints and their repair kits are available, suitable for normal or l
ow temperature, or H2S environments, with sizes ranging from 2" to 4" and rated WP
ranging from 6000-20000psi(42Mpa-140Mpa).
3 We can supply long and short radius swivel joints. Long radius swivel joints can minimize
fluid shock, and has better performance of resistance for scouring and erosion. We also need
to use short radius swivel joints for low pressure operation due to limited installation space.
4 Patterns of swivel joint are made in NC machine tools, with even wall thickness and
longer service life. Wall thickness difference of inner and outer arcs can meet FMC standard.The three-ball-race design can bear heavy load stably, and ensure less vibration with
variable load.
5 All sizes of swivel joints can be interchanged with FMC equivalent products used in cementing
and fracturing equipment.
6 Sealing parts made of synthetic rubber with release hole are fitted with blowout preventing
metal ring. When sealing parts leak, pressure will be automatically relieved. Safety performance
is enhanced.
7 Usually good lubrication can ensure that swivel joints work normally without much maintenance.
