Produktdetails
AL6XN lap joint flanges are backing flanges designed to work with lap joint stub ends, allowing the flange to rotate freely for easy bolt alignment during installation. Manufactured in high-alloy 6-moly super austenitic stainless steel, they are widely used in seawater, Sole, Rauchgasentschwefelung, Zellstoff und Papier, offshore and chemical processing systems where superior resistance to pitting, crevice corrosion and chloride stress corrosion cracking is required.
SASA FLANGE supplies AL6XN lap joint flanges in standard and custom sizes to ASME, EN, DIN, JIS and GB dimensions. Each batch can be provided with chemical analysis, mechanische Prüfung, dimensional inspection and PMI verification. We also offer machining to suit matching stub ends, mit EN 10204 3.1 Zertifikat, clear heat number identification and full material traceability for critical industrial projects.

Produktinspektion
1. Inspektion der chemischen Zusammensetzung
Chemical analysis is carried out to verify that the AL6XN material meets UNS N08367 composition requirements, especially chromium, Nickel, molybdenum and nitrogen content. This is essential for confirming corrosion resistance in chloride service. Test results are reviewed against the applicable material standard and recorded on the mill test certificate for full traceability.
2. Prüfung der mechanischen Eigenschaften
Mechanical testing is performed to confirm tensile strength, Streckgrenze, elongation and hardness of the supplied AL6XN flange material. These checks help ensure the flange can withstand installation loads and operating conditions. Where required, test reports are linked to the heat number so the buyer can verify compliance with project specifications.
3. Maßprüfung
Each lap joint flange is inspected for outside diameter, Dicke, langweilig, Lochkreis, bolt hole quantity and hole diameter according to ASME, EN or customer drawings. The lap joint seating dimensions are also checked to ensure proper fit with the stub end. Accurate dimensions are critical for smooth assembly and leak-free service.
4. PMI-Tests und hydrostatische Tests
Positive Material Identification is available to confirm the supplied flange is genuine AL6XN / UNS N08367 and not substituted with lower alloy stainless steel. As lap joint flanges themselves are non-pressure-containing loose backing components, hydrostatic testing typically applies to the assembled piping system or matching stub end arrangement. EN 10204 3.1 certificate is provided on request.
