Produktinspektion
1. Inspektion der chemischen Zusammensetzung
Chemical composition inspection is carried out to verify that the AL6XN material meets the required limits for chromium, Nickel, Molybdän, nitrogen and other alloying elements. This is essential for corrosion resistance in chloride-bearing environments. Test results are reviewed against the applicable standard and corresponding mill test certificate before production release.
2. Prüfung der mechanischen Eigenschaften
Mechanical testing is performed to confirm tensile strength, Streckgrenze, elongation and hardness values for the supplied material condition. These tests help ensure the flange can withstand assembly loads and service stresses. Für Projektaufträge, test records can be linked to the heat number and provided as part of the quality dossier.
3. Maßprüfung
Each lap joint flange is checked for outside diameter, Bohrungsgröße, Dicke, Lochkreis, Lochdurchmesser, number of holes and facing geometry according to the applicable standard. Dimensional inspection is important for proper fit-up with stub ends, gaskets and mating flanges, reducing installation problems at site and ensuring interchangeability.
4. PMI-Tests und hydrostatische Tests
PMI testing is conducted to confirm the alloy identity of AL6XN material and prevent grade mix-up during manufacturing and packing. While hydrostatic testing is generally applied to assembled piping components rather than loose flanges, related inspection support can be provided for project requirements. EN 10204 3.1 Zertifikat, PMI reports and inspection records are available on request.
