Hello All,

I came up with a bunch of very good papers that are available at this address:

the following subset are papers that are specifically for piping vibration problems:

17. Escape Piping Vibrations While Designing, J. C. Wachel/C. L. Bates, Hydrocarbon Processing, October, 1976, pp. 152-166.

20. Field Investigation of Piping Systems for Vibration-Induced Stress and Failures, J. C. Wachel, Pressure Vessel and Piping Conference, ASME Bound Volume #H00219, June 27-July 2, 1982.

27. Piping Vibration and Stress, J. C. Wachel, Vibration Institute, Machinery Vibration Monitoring and Analysis Seminar, New Orleans, April 1981, pp. 1-20.

29. Pulsations in Centrifugal Pump and Piping Systems, C. R. Sparks and J. C. Wachel, Hydrocarbon Processing, July 1977, pp. 183-189.

37. Techniques for Controlling Piping Vibration and Failures, J. C. Wachel/C. L. Bates, ASME Paper 76-PET-18, 1976.

59. Vibration Troubleshooting of Existing Piping Systems, J. C. Wachel/D. R. Smith, July 1991.
