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.
