Large size flexible rubber expansion joint with tie rod control
ADVANTAGES
1.Outstanding pressure resistance
It excels in pressure resistance by the combination of spherical structure with super stability against internal pressure and strong special reinforcing nylon.JINGNING flexible connector display an outstanding pressure resistance of bursting pressure.
2.Superior absorption of vibration-noise-shock
JINGNING single sphere flexible rubber joint are engineered to reduce vibration ,noise and movenment inherent in piping systems.JINGNING will enable the isolated equipment to move freely ,eliminating vibration and repelling sound which is prevalent in metallic type joint.
3.Compensate greater elongation, compression , lateral and angular movement
Equipment such as pump ,chillers,cooling tower,compressors and piping systems move out of alignment due to wear,load stress and during the setting of foundation blocks.JINGNING flexible connector for lateral ,torsional and angular movement to prevent damage ,which elimate costly downtime in plant operation.
