Actually, this is covered by the Southern Acadian Directorate rule, SAD-CUNAS-1, which says: Piping ID shall in all cases be less than OD, otherwise the contained material will be on the outside of the pipe, promoting spills.....

   Two sets--

   The plant production manager rule--
   Retire it just before the line bursts. ;->

   Scaredy-cat engineering rules--
   Retire it when the wall thickness is reduced to the minimum allowed by    code for your particular system, or if defects like cracks appear that    would not be acceptable under Code rules for the system.

   Plant maintenance rules--
   Don't fix what ain't broke yet.
