How EU buyers ensure EN 1092-1 flanges are compliant with QA standards using PMI, Hydrostatic, Ultrasonic, Radiography and sealing face roughness tests.
📘 What you’ll learn:
- ✅ Key QA methods for EN 1092-1 flanges
- 🔍 Why PMI, Hydro, UT & RT matter for compliance
- ⚡ EU buyer expectations during inspection
- 📝 How to request QA documents in your RFQ
In Europe, quality assurance is non-negotiable. EN 1092-1 flanges must not only match dimensional standards but also pass strict testing & inspection protocols. Here’s how EU buyers confirm flange reliability before approving supply.
Key Flange QA Tests in Europe
🔹 PMI (Positive Material ID)
Verifies chemical composition via spectrometer. Ensures correct stainless/duplex grade before dispatch.
🔹 Hydrostatic Test
Flange is pressurized with water to confirm pressure capacity (PN10–PN100). Reports attached with MTCs.
🔹 Ultrasonic / Radiography
Detects internal flaws, porosity or cracks in forged/welded flanges. Used for critical EU applications.
🔹 Sealing Face Roughness
Checks Ra value of raised/RTJ faces. Smoothness ensures gasket integrity & leak-free operation.
What EU Buyers Expect
- ✔ Full QA package with EN 10204 3.1 or 3.2 certificate
- ✔ Test reports attached (PMI, Hydro, UT/RT)
- ✔ Third-party inspection if required (TÜV, Lloyd’s, SGS, DNV)
- ✔ Traceable heat numbers marked on every flange
