are designed with moulded rubber flanged ends with bolt holes that accommodate standard steel flanges. They are furnished with or without helical wire reinforcement. Special tubes can be compounded to meet unique service conditions in either suction or discharge applications.

Percentage of Reduction of Vibration Input with Frequency and Pressure as Compared to Steel Pipe

Center Freq. Hz 8″ I.D. X 24″ F-F
Vibration Joint
10 PSIG 50 PSIG 80 PSIG
440 87% 91% 93%
68 95% 96% 99%
125 98% 99% 99%
250 96% 97% 99%
500 91% 93% 94%
1000 82% 91% 96%
2000 99% 99% 99%
4000 99% 99% 99%
8000 97% 97% 98%

Example: If a steel piping system had a major vibration frequency of 1,000 Hz at 50 PSIG and and 8″ rubber expansion joint was installed in the pipeline, the percentage of reduction of vibration would be 96%
