Organising Pipeline Thickness Records for Review

Keep component identity separate from position

An identifier is intended to refer to a particular component; a position describes where it was recorded at a particular time. A pipe may have moved, so an old position label should not automatically be treated as its current identity. Use the labels in the original report and identify uncertainty rather than inventing a match.

Where the file contains a drawing, photograph key or component list, retain it with the readings. A spreadsheet detached from its location key can lose important context even when every number has been copied correctly.

Preserve the original record and its notation

Keep the original report, date, issuer and revision reference. If you create an administrative index, label it as an index rather than a replacement test record. Retain the original units and notation; do not silently convert, round or average values to make columns look consistent.

Different reports may use different location conventions or describe different equipment configurations. Flag those differences for the reviewer. Sorting values into a timeline does not establish that the measurements are directly comparable.

An index for review

• Source report and page reference.
• Component identifier exactly as recorded.
• Recorded position or location-key reference.
• Test date shown in the source.
• Missing pages, unclear labels or uncertain matches.
• Question to be answered by the reviewing specialist.

Make missing information visible

An empty cell may mean no information was supplied, a location was not recorded or a document is incomplete. Use plain status labels in your index, leaving the source report unchanged. Never insert a zero or carry forward an earlier value merely to complete a table.

If a component appears in an inventory but not in the available report, ask whether another document exists. Do not classify it as tested, untested or acceptable from that absence alone.

• Discuss pipeline record reviewProvide the original records and identity questions so the scope of any further work can be considered.

Ask for interpretation separately

Describe what you need the professional to clarify: identity, completeness, comparability or the need for further assessment. The reviewer may need information that your archive cannot provide, and an organised file does not remove that limitation.

This guide gives no thickness threshold, test interval or discard rule. Do not use colour coding, trend lines or a spreadsheet formula to imply fitness for service. If your index includes an earlier professional status statement, quote its reference and date rather than presenting it as a new conclusion.
