製品検査
1. 化学成分検査
Chemical analysis is carried out to verify that the AL6XN material meets UNS N08367 composition requirements, especially chromium, ニッケル, 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. 機械的特性試験
Mechanical testing is performed to confirm tensile strength, 降伏強さ, elongation and hardness of the supplied AL6XN flange material. These checks help ensure the flange can withstand installation loads and operating conditions. 必要な場合, test reports are linked to the heat number so the buyer can verify compliance with project specifications.
3. 寸法検査
Each lap joint flange is inspected for outside diameter, 厚さ, ボア, ボルトサークル, 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試験と静水圧試験
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.
