Double arch rubber joints, also known as double sphere rubber joints, are designed for piping systems to absorb pipe movements, relieve stress, as well asreduce system noise/vibration.
Double Arch Rubber Join
Double arch rubber joints, also known as double sphere rubber joints, are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate misalignment/offset and protect rotating mechanical equipment against start-up surge forces.
Features and Benifits
·Absorbs directional movement
·Absorbs vibration, noise and shock
·Compensate misalignment
·Double arch design, more flexibility
·Economical fully molded construction
·Special grooved flange ring design, prevent rubber end pulling out
·Solid galvanized steel floating flanges speed the installation time
·No gaskets required; integrally rubber flanged design

NOTES:
1. Control units must be used when piping is not properly anchored.
2. The rated pressure 2.5MPa products will only be sold with control units.
3. Pressure rating is based on 30℃ operating temperature. The pressure rating is reduced at higher temperatures.
4. Weights in the above table are joints with DIN PN16 drilling retaining ring flanges.
5. Movements shown in the above table are non-concurrent.
6. Rated pressure in the above table is the maximum "working pressure". Test pressure is 1.5 times "working pressure", Burst pressure is 4 times " work pressure".
7. Normally, the flange drilling is based on DIN PN16, ANSI 150/250/300 lbs, BS PN10, JIS 10K are also available upon request.
