Link Valve Overhaul NDT and Test Records

An overhaul dossier should let a recipient follow one identified valve through receipt, dismantling, examination, repair, reassembly and any separately required testing. The job number alone may not be enough when a workshop receives several similar valves from the same client. Start by distinguishing the owner's equipment tag, the manufacturer's identifying information, the workshop reference and the identity used on individual removed components. Record where each identifier came from. A temporary shop label can be useful for handling, but its relationship to the owner's record should remain explicit throughout the work.

Treat the dossier as an index to evidence, not as a single assertion that the valve passed everything. An NDT report describes the examination and its bounded findings. A pressure-test record, dimensional record, repair authorization and final release document may answer different questions. Bringing them together makes retrieval easier; it does not make their conclusions interchangeable. This guide focuses on organizing that relationship using a free reporting workspace and an editable component record, without supplying repair instructions, test pressures, acceptance limits or authority to return equipment to service.

The applicable examination and repair requirements need to come from the actual assignment: the owner's approved instructions, the relevant engineering disposition and the documents incorporated by the contract. Enter the document identifier, edition or revision and the scope to which it applies. Do not choose an acceptance basis merely because a familiar standard appears on an old template. If the scope changes during dismantling or repair, retain the corresponding authorization reference and explain which later examination records address the changed work. Open questions should remain identifiable until the responsible party resolves them.

ASME's public B16.34 description identifies a new-construction standard covering several valve requirements, including examination and testing. That scope should not be silently converted into a universal overhaul specification. In a repair dossier, state the requirements actually invoked for this valve and have the appropriate authority resolve their application. NDT Connect can record the selected reference and the user's finding; it does not determine which repair code applies or certify that a maintenance package satisfies it.

When the valve is dismantled, use a component list that preserves the relationship between the assembly and the body, bonnet, stem, closure element and other parts included in the work. Use the actual component terminology for the valve design. Identify which items have their own serial or traceable mark and which rely on the controlled shop association. If two similar components are exchanged, document the exchange rather than assuming that every part in the final assembly is the same one received. A clear association prevents an examination report for one loose component from being attached to another by convenience.

Where a mark is unreadable or absent, preserve that fact and identify the approved identification method used by the workshop. Do not manufacture an original serial number to make the table appear complete. A photograph, receipt record or controlled traveler may support the association, depending on the organization's process, but the report should describe the evidence it actually references. When a part is removed from the job permanently, retain its disposition and avoid leaving it in the final assembly list. The historical record should still explain why it was examined and what happened to it.

A finding has a time and a physical context. An examination performed on the received condition, after cleaning, after a particular repair operation or before reassembly does not necessarily describe the same state of the component. Put the work stage in the examination record and connect it to the relevant traveler or repair reference. The author should not have to rely on a filename date to explain whether a reported indication was observed before or after the authorized work. Use the terminology agreed for the job so the dossier and workshop records remain understandable together.

When later work changes the examined area, keep the earlier report as historical evidence and identify any subsequent examination separately. Do not simply replace its result with a new outcome while retaining the original examination date. If the same component is examined several times, create a stage sequence that shows what changed between visits and which records apply to the final condition. The purpose is to make the evidence chain visible. Deciding which examinations are required at each stage remains part of the approved repair and inspection process, not a decision supplied by the reporting template.

Describe the area actually examined using component features, a drawing or another reproducible reference. A body report may cover selected accessible areas rather than the entire pressure boundary; a stem report may relate to a particular portion or condition. Avoid broad phrases such as full valve NDT when the evidence concerns only one component or one defined surface. Record the limitations reported by the examiner and their practical boundary. If a drawing marks the zones, include its identifier and revision so a later recipient can interpret the references correctly.

Keep access limits, scope exclusions and unresolved documentation separate. An excluded component was outside the authorized work; an inaccessible area may have been within the intended scope but not examined; a missing report is a delivery problem. Combining all three under not done prevents the owner from understanding what action is needed. The result table can include a concise status and point to a fuller explanation. Do not convert an unexamined area into an acceptable result because the rest of the component has a satisfactory finding under the supplied criteria.

A repair record should connect to the component identity and the physical zone it concerns. Retain the responsible authorization reference, the work description supplied by the authorized party and the related completion evidence. The NDT report can refer to that repair without claiming to approve the design or repair method itself. If the scope changed after an initial examination, explain the relationship between the original finding, the approved disposition and the later examination. This is particularly helpful when one valve contains several independent repair decisions that reached different stages at different times.

NIST's research on linking design, manufacturing and inspection information examines the challenges of connecting lifecycle records. The editorial application here is modest: keep the repair reference and its examination evidence connected to the same component and work stage. The free reporting tool does not create an automated engineering data connection. Someone still needs to check that the document identifiers, revisions and physical associations are correct before the package is presented as the evidence for a completed repair.

Where pressure or functional testing forms part of the authorized scope, record the separate test reference and the identity of the assembly or component tested. Do not relabel an NDT result as proof of a pressure-test outcome, or use a pressure-test outcome to erase an unresolved examination finding. The records can support the same final decision while remaining distinct evidence. Include the test document's status and revision as supplied by the responsible testing process, and identify any missing reference as an open deliverable rather than filling in an assumed successful outcome.

The dossier index should also show whether the tested configuration matches the configuration being handed over. A component substitution, later repair or disassembly may require a specific review under the governing process; the index should make the change visible so the responsible authority can determine the consequence. This guide does not prescribe retesting rules. Its contribution is a reliable record of what was tested, when, in which configuration and where the authoritative result can be found. That clarity prevents a valid document from being used to support a different physical state without an explicit review.

Consider a fictional valve received under owner tag V-214 and workshop job OV-106. The body is associated with component record B-01, and the removed stem with S-01. The initial NDT report documents defined body areas in the received condition. A later authorized repair affects one body zone, while the original stem is replaced by another identified item. The dossier should not simply say valve repaired and tested. It should show the body examination history, the repair authorization, the later body examination and the component substitution that changes the final assembly list.

In this example, the final pressure-test report is a separate record for the reassembled configuration. The index lists it alongside the applicable examination reports and the release reference, without merging their conclusions. If the replacement stem's required supporting document has not arrived, that missing evidence remains an open item even if another record is complete. The coordinator can then request exactly what is missing. The example supplies no acceptance decision; it demonstrates how a dossier can preserve several different evidence states without allowing the most recently received PDF to conceal the unresolved one.

Start with columns for owner tag, shop job, component identity, work stage, examination zone, report reference, repair reference, other test reference and open action. Long technical descriptions can remain in the underlying report, while the index carries enough information to locate it. Use separate rows where one component has several stages or examination methods. A single overloaded cell containing every report number may save horizontal space but makes it difficult to see which result applies to the final condition. Add a concise legend for the status terms used in the index.

Before importing the table, check that each identifier remains text and that blank fields have a deliberate meaning. A separate explanatory note can distinguish no separate test required under the authorized scope from test report outstanding. The free digital NDT reporting workspace can import editable tables from Word or Excel and lets the author adjust headers, columns and rows. It does not retrieve the referenced reports automatically. Keep the index manageable, and use the established document storage system for the supporting evidence rather than trying to reproduce an entire workshop archive in one result table.

Enter the job and component context in the relevant report fields, then add the reviewed result or index table. Identify the actual procedure and requirements supplied for the examination. Put scope limits beside the findings they qualify and check that the final conclusion stays within the examiner's authority and evidence. Company and client logos can help identify the document parties, but they should not be used to imply an approval that has not occurred. Before downloading, inspect long tags, revision identifiers and drawing references for truncation or unclear wrapping.

A draft PDF can be produced without signup. A verified free account supports saved private reports with assigned numbers and separate revisions. Choose a report-numbering convention that complements the workshop's existing identity system, then retain the owner and job references in their own fields. Changing a client reference later should not require pretending that the examination itself was a different event. Use the appropriate saved-report revision process for changes to an issued version, and keep the separate dossier index aligned with the report number and revision actually delivered.

A workshop may send an examination report before the complete overhaul package is available. Identify that delivery as a defined subset and list the records included, their revisions and the records still outstanding. When the remaining documents arrive, update the index deliberately. Do not rely on the recipient to combine several email attachments correctly or infer that the newest message cancels every earlier file. A short package reference and revision can help the customer distinguish the current index from an interim delivery.

Record delivery acknowledgments separately from technical acceptance. A customer confirming receipt has not necessarily approved the repair evidence or released the valve. If a later report revision changes the dossier, identify which prior document it replaces and retain the authorized redistribution record. For a large package, check one component through the final delivered folder rather than through the workshop working folder. That verifies the material the recipient actually received, including any supporting document whose filename or location changed during packaging.

Before handover, compare the final assembly list with the component and stage index. Check that the reports cited for the final condition refer to the right parts and that superseded, removed or replaced items remain understandable as history. Then review the open-action column. An item marked complete should point to the evidence that supports that status; an unresolved question should identify an owner and next step. If a customer accepts a bounded package with outstanding matters, record the actual authorization reference and scope instead of silently deleting the open rows.

The equipment tracker can support the instrument record, and the procedure draft workspace can help organize a document for responsible review. These tools do not supply workshop approval, an engineering disposition or a valve release certificate. The handover is strongest when its records remain precise about their role. A recipient should be able to move from the owner's tag to the final component configuration, then to the relevant examination, repair, separate testing and authorized release evidence without having to reconstruct the story from filenames.
