제품검사
1. 화학성분 검사
Chemical composition inspection is carried out on the Hastelloy B2 raw material and, 필요한 경우, on the finished flange to verify compliance with UNS N10665 요구 사항. Key elements such as nickel, 몰리브덴, 크롬, iron and carbon are checked against ASTM limits. This process helps confirm corrosion-resistant performance and prevents off-grade alloy substitution in critical project supply.
2. 기계적 성질 테스트
Mechanical properties testing verifies that forged Hastelloy B2 material achieves the specified tensile strength, 항복강도, elongation and hardness after heat treatment. Test samples are reviewed according to relevant ASTM requirements or project specifications. These tests confirm the flange has sufficient structural integrity for pressure-retaining service, welded assemblies and demanding nozzle or vessel connections.
3. 치수검사
치수 검사는 외경을 커버합니다., 구경, 허브 길이, long neck profile, 두께, 볼트 서클, bolt hole diameter and facing geometry. Raised face or RTJ groove dimensions are checked carefully to ensure gasket compatibility and correct assembly. This inspection is especially important for long weld neck flanges used on vessels and equipment where transition dimensions must match design drawings precisely.
4. PMI 테스트 및 수압 테스트
PMI testing is performed using portable analyzers to confirm the alloy identity of Hastelloy B2 before shipment. When specified, hydrostatic or assembly pressure testing is arranged to verify pressure integrity in finished systems or special fabricated components. SASA FLANGE 제공할 수 있다 EN 10204 3.1 자격증, material test reports, inspection records and traceable heat numbers with the delivered flanges.
