TM 310 310-R BE-310 320 SERIES 300 flanged rubber pipe connectors PROCO Series 300 Rubber Pipe is designed for tough demanding industrial and commercial applications as found in: Chemical-Petrochemical and Industrial Process Piping Systems, Power Generating Plants, Steel Mills, Marine Services, Pulp/Paper Systems, Water-Waste/Water-Sewage and Pollution Control Systems. Specific equipment applications could include: Pumps, Cooling Towers, Compressors, Blowers, Fans, Absorption Machines, etc. Installed next to mechanical equipment or between the anchor points of a piping system, specify the PROCO Series 300 to: (1) Isolate Mechanical Vibration, (2) Reduce System Noise, (3) Absorb Pipe Movement/Stress, (4) Compensate Alignment/Offset, (5) Eliminate Electrolysis, (6) Protect Against Start-Up/Surge Forces. When you need an engineered rubber solution to a piping system problem, call PROCO. Engineered For Your Application. Each PROCO Series 300 Rubber Pipe is constructed withAbsorbs Pipe-Wall and Fluid-Borne Noise.

For major two-plane vibration/motion it is best to use two flexible rubber pipe con- nectors installed at right angles, one to absorb the horizontal vibration and one to absorb the vertical vibration. A tension anchor is usually advisable to stabilize the elbow between Table 1: Comparison of Material Acoustical Impedances the connectors. Note: For maximum vibration transmission reduction, the piping sec- tion beyond the rubber connector must be anchored or sufficiently rigid.
