Product Description

Introduction of rubber joint

Rubber expansion joint is also known as flexible rubber joints, rubber soft connection, soft joint, flexible rubber joints, rubber expansion joints, suspension throat, shock absorber, is a kind of pipe connecting piece with advantages of high elasticity, high air tightness, medium resistance and weather resistance.

Usage of rubber joint

Protecting piping and equipment system from stress or motion.

ADVANTAGES of rubber joint

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.Runtaida flexible connector display an outstanding pressure resistance of bursting pressure.

 

2.Superior absorption of vibration-noise-shock

Runtaida single sphere flexible rubber joint are engineered to reduce vibration ,noise and movenment inherent in piping systems.Joint installation of the Runtaida 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.Runtaida flexible connector for lateral ,torsional and angular movement to prevent damage ,which elimate costly downtime in plant operation.

Characteristics of rubber joint

It take advantages of rubber, such as high elasticity, high air tightness, medium resistance, weather resistance and radiation resistance, it can reduce the vibration and noise of pipeline, and it can play the role of compensation for thermal expansion and contraction caused by temperature change.
