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.
Because of rubber has superior capability in resistance of acid, alkali, oil, and electrolytic, Rubber Expansion Joint has become one of the alternatives of stainless steel and been successfully installed in tough demanding applications such as: Chemical/Petrochemical, Marine, Power Generation, Pulp/Paper, Steel Mills and Water/Wastewater Treatment.
2.Rubber expansion joint Features and Benefits
1, Versatile hand-built construction. Made in China 2, Absorbs directional movement 3, Absorbs vibration, noise and shock 4, Compensates for misalignment 5, Wide flowing arch design 6, Virtually eliminates sediment buildup 7, Economical fully molded construction 8, High vacuum rating (up to 30" Hg) can be supplied for certain sizes 9, Special grooved flange ring design, prevent rubber end pulling out
10, Solid galvanized steel floating flanges speed the installation time 11, High tensile aircraft cable is embedded in the raised face rubber ends to prevent pull out and avoids the sharp cutting edge of solid steel rings 12, No gaskets required; integrally rubber flanged design, no gaskets required, DIN PN10/16 drilling standard, other flange drilling available, including ANSI 150lb/300 lb, BS, and JIS
