제품검사
1. 화학성분 검사
Chemical analysis is carried out to verify that the AL6XN material meets UNS N08367 composition requirements, especially chromium, 니켈, 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. 기계적 성질 테스트
Mechanical testing is performed to confirm tensile strength, 항복강도, 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. 치수검사
Each lap joint flange is inspected for outside diameter, 두께, 구경, 볼트 서클, 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 테스트 및 수압 테스트
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.
