TECHNICAL REFERENCE

What Belongs in a Pressure-Vessel Manufacturing Data Record?

Cross-check every record against the tag, revision and ITP before final issue.

DIRECT ANSWERThe manufacturing data record is the as-built evidence for the identified vessel: approved drawings and changes, material certificates and traceability, welding and qualification, NDE, heat treatment, tests, dimensional checks and release. The contract defines exact contents and format.

MDR index

  • Identification, approved design and as-built revisions
  • Material, weld map and personnel/procedure links
  • NDE, repair, PWHT and pressure-test results
  • Concessions, inspection release and packing records

Relevant manufacturing capability

  • Drawing, datasheet and equipment-list manufacturability review
  • Self-manufactured and coordinated-supply scope identification
  • Technical, quality, document and delivery clarification

Key notes

  • A document count or unsigned template does not demonstrate dossier completeness.

FAQ

Frequently asked questions

01When should the MDR index be frozen?
