Yu-xiang® double sphere rubber expansion joints are designed for
piping systems to absorb pipe movements, relieve stress, reduce
system noise/vibration, compensate for misalignment/offset and to
protect rotating mechanical equipment against start-up surge
Yu-xiang® double sphere rubber expansion joints are inherently
stronger than the conventional hand-built style spool arch type.
Internal pressure within a “sphere” is exerted in all directions,
distributing forces evenly over a larger area. The spherical design
“flowing arch” reduces turbulence and sediment buildup.
Features and Benefits:
Absorbs Directional Movement
Thermal movements appear in any rigid pipe system due to
temperature changes. Yu-xiang® double sphere rubber expansion
joints allow for axial compression or axial extension, lateral
deflection as well as angular movement.
Yu-xiang® double sphere rubber expansion joints have branded
elastomer designations. Neoprene Tube/Neoprene Cover (NN) and
Nitrile Tube/Neoprene Cover (NP) elastomer designated joints meet
the Coast Guard Requirements and conform to ASTM F1123-87.240C/NP-9
joints have ABS certification.
AllYu-xiang® double sphere rubber expansion joints 1.0” I.D. thru
12” I.D. are available with tapped (threaded) holes and must be
specified at time of order. In addition to standard 150 lb. drilled
flanges, Yu-xiang® can provide expansion joints listed above in
150/250/300 lb. drilling, BS-10 (British) drilling, Metric PN10 and
PN16 drilling and JIS 10kg/cm drilling.
