How To Verify UNS N08825 Weld Neck Flanges Test Certificates ?
Check Heat Number Traceability
Cross-verify the MTC heat number against the original mill certificate on file.
Confirm A PMI Report
Positive Material Identification should back every batch before it leaves the yard.
Match Chemistry To ASTM B564
Ni, Cr, Mo, Cu and Ti figures must sit inside the certified specification window.
Verify The NABL / Third-Party Stamp
Look for independent lab accreditation on the dimensional and mechanical test report.
Cross-Check The Dimensional Report
Confirm bolt circle, bore and face tolerance sit within ASME B16.5 limits.
Request A Certificate Of Origin
Needed for customs clearance and for confirming true country of manufacture.
