Your challenge is a valid one. The cost to the plant in replacing the lines involves shutting down the process while drains are replaced. That downtime is difficult to arrange (plant is running at capacity), but would be required if the line needs replacement (the initial evidence suggests...

I forgot to include the pipe size in my earlier post. The drains are 4" dia.

I've got perhaps an easy question on a topic I have little experience with. A project to replace drain piping in my plant found sections of pipe with material loss, and in one instance, failure of the pipe. Because we have multiple drain lines throughout the facility, I'd like to inspect other...

Funny that you should ask. We have an operator who was shown how to take basic measurements at set positions (1H, 1V, etc). I have passed Emerson's level 1 ISO training, but have little experience taking the measurements myself. Unfortunately no one else at our plant has any expertise or...

Thank you all for the feedback. We're going to start by pulling the motor for the second pump, which had the high frequency vibration. Prior to pulling, a check will be performed to ensure everything is lined up & vertical. The sidebands are at 1x run speed (1800 rpm / 30 Hz); not sure if...

1gibson, that's a novel solution, and one we should be able to implement when the misaligned pump is pulled. Thank you for the input.

I have an interesting dilemma in my utility plant. I currently have two vertical turbine cooling tower pumps, same model & vintage, that each have a vibration issue. The first pump is a 1.1 ips 1x vibration in one direction at the motor outboard. The second pump has a loud buzzing noise...
