The rubber epansion joints are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, and compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces.
The Flexible Rubber Joint is composed of reinforced fabric rubber body and metal flanges or threaded live joints, which is widely used in the systems of water supply, drainage, water circulation, heating and ventilating, and air conditioning, and the piping systems of the paper-making, the petrochemical industry, marine, compressors pumps and fans etc. 
In Yinlong, rubber joints can be sphere type rubber joint, wide arch rubber expansion joint,  rubber elbow, etc.

Sphere Rubber Joint: 
Easy to install and maintain because of the small volume and flexibility.
Structural noise transmission can be reduced with the restrict and flange non-parallelism.
With high resistance of acid, alkali, oil, and electrolytic.
Cost effective and long service life.

Wide Arch Rubber Expansion Joint
KDJF wide arch rubber expansion joints are widely applied to petroleum, petro-chemistry, chemical industry, electric power, thermal energy, water conservation, metallurgy, aviation, astronautics, ship, nuclear industry and pressure vessel and so on.This kind rubber expansion joint has higher pressure rating and stronger corrosion resistant than normal expansion joint.

WTX Elbow Rubber Joint
Ideal products for connecting a ball valve and circulating pump.
High-pressure, high-temperature, corrosion resistance.
Reducing the vibration and the noise of the piping system.
According to different material requirement to suit different medium and environments.
Cost effective,easy maintenance and long service life.
