PIPELINES SHOULD HAVE TRACEABLE, VERIFIABLE, AND
COMPLETE RECORDS,
including material documentation to
support maximum allowable operating pressure (MAOP) validation.
But what about pipeline segments that are decades old? Or assets
that were once managed by one operator, sold to another, and then,
potentially, sold again?
The answer? Pipe Identification (PI).
Correlate existing pipe records,
if any, to the PJC bins.
If all records align to a characterized
pipe bin, Pipe Identification has
been achieved.
If records gaps persist,
proceed to step 3.
Employ Positive Material
Identification (PMI)
– an in-situ non-destructive evaluation
methodology – to identify material
properties where records do not exist for
a given pipe joint or PJC bin. With all pipe
joints aligned to the appropriate bin, and
remaining gaps closed through PMI,
Pipe
Identification has been achieved.
