DIRECT ANSWERAn old nameplate helps identify historical tag, manufacturer and rated conditions, but it cannot alone define a new pressure vessel. Reconstruct current service, design cases, applicable rules, measured interfaces and approved design documents.
Replacement evidence
- Nameplate and original dossier identity
- Current process and relief design basis
- Site measurements and changed interfaces
- Applicable current design and approval route
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
- An illegible or old rating must not be treated as a current design approval.
