Much more information is needed. We have seen instance of corrosion from the end user not understanding the metallurgy required in the RO with the fluid and the particulate together. This can cause severe degradation over short periods of time. How often are you having a shutdown with...
You need to provide more information for a solution. What is the fluid type, temperature, pressure before the orifice and after, pipe size. Do you have any bends in the pipe within so many pipe diameters of the RO? Does the noise occur when the pump reaches a certain threshold. If the other two...
