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 forces.

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.

Material Identification
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
