Pipe EOL....
Pipe EOL....
(OP)
I am looking for a little validation on this as I haven't thought of it this way. So you use CA, mill tol, pressure, etc to calculate a required thickness per B31.3. Using this you select a schedule that has a nominal thickness. An API inspector is telling me that end of life for the pipe would be nominal - CA. From this you can then perform FFS API579 techniques to extend life if so desired. Seems to me like this could lead to premature replacement. Particularly if you do not have beginning of life UT readings to know pipe thickness from the mill. Ideas, thoughts on this would be apreciated.

Your inspector seems overly conservative.

The approach you describe sounds like a bet that corrosion/erosion will never appear when the mill delivers the minimum wall allowed per specification.
Murphy is betting against the projects which take this approach.
