Swivel joints, with integral ball bearing, are manufactured on the basis of technologies from FMC, USA. Various models of swivel joints and their repair kits are available, suitable for normal or low temperature, or H2S environments, with sizes ranging from 1" to 4" and rated WP ranging from 2,000psi ~ 20,000psi. 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.
