API 6FA Inspection & Test Plan (ITP)
A typical stage-wise ITP / quality plan for valves supplied to API 6FA — inspection activities, tests, acceptance references and verifying documents, with recommended hold, witness and review points for QC and third-party inspection.
What is the ITP for API 6FA valves?
An Inspection & Test Plan (ITP) sequences every check between raw material and dispatch, and assigns each an inspection level — Review (document check), Witness (inspector may attend), or Hold (work stops until released). The plan below is a typical ITP for valves built to API 6FA (Specification for Fire Testing of Valves); the tests and documents are drawn directly from the standard's requirements. Use it to structure your QAP or coordinate third-party inspection.
1. Documentation & design review
Review- Approval of drawings, datasheets and QAP against API 6FA
- Fire exposure test: 750–1000°C for 30 minutes
- External leakage through stem and body joints ≤200 mL/min during and after fire
2. Raw material verification
Review- Material Test Reports (MTRs) review per EN 10204 3.1/3.2
- Positive Material Identification (PMI) of pressure-containing parts
3. Dimensional inspection
Witness- Dimensional check per API 6FA / ASME B16.34 / applicable face-to-face
- Wall thickness verification
4. NDE (as applicable)
Witness- Visual, and RT/UT/MPI/DPT of castings/welds per specification
5. Pressure & performance testing
Hold- Fire test: 750–1000°C for 30 minutes in gas-fired or propane furnace
- Post-fire leakage: seats ≤200 mL/min, stem/body ≤200 mL/min
- Post-fire operation: full open/close cycle
- Certificate of qualification (CoQ) required from third-party test facility
Primary hold point — witnessed shell, seat and backseat tests.
6. Fire-type test (qualification)
Hold- Fire test per API 607 / API 6FA with post-fire leakage acceptance
7. Marking, painting & preservation
Review- Nameplate & body marking verification
- Painting/coating DFT check, end protection and preservation
8. Final documentation
Hold- API 6FA fire test certificate per model/size range
- Third-party test laboratory certification
- Bill of Materials confirming same construction as tested valve
- Production test certificates (hydrostatic + seat)
Final documentation review before release/dispatch.
This is a typical ITP framework populated from API 6FA requirements, for reference. The actual hold/witness/review split is agreed per project between purchaser, manufacturer and the third-party inspection agency in the approved QAP. Confirm project-specific requirements before use.
