Hanger and spring support-related
installation oversights are responsible for many excessive pipe
stress incidents. Piping-induced loads will often cause pump
casings to deflect. Consequently, important internal parts,
especially bearings and mechanical seals, become misaligned and
fail prematurely. Pump reliability improvement efforts must,
therefore, include verifying acceptable pipe stress values. It
would be very difficult to ascertain that fluid machinery nozzle
loads are within acceptable limits unless a computer- based pipe
stress analysis has been performed first. This stress analysis will
also confirm if the tentatively selected pipe supports are
appropriate for the job.
