My take. My experience show otherwise. Most if not all of the designers ive work with are competent and show good judgement. Im talking about the guys who operate the PDS. The same goes to the engineers repsonsible for ensuring that affected process piping are code compliant.

My take. Well vibration do not necessarily pop out wnenever a support or line stops are provided or where changes in pipe direction exist. Perhaps other problem, but not vibration. And when a process piping do encounter a severe vibration, the location where its happening is not always obvious. Received on Sat Jan 13 08:15:00 2007
