製品検査
1. 化学成分検査
Chemical composition inspection is performed on raw material and, when required, on finished forgings to confirm conformity with the specified Incoloy grade. Key alloying elements such as nickel, クロム, モリブデン, copper and titanium are verified against applicable ASTM requirements. This process helps ensure corrosion resistance, high-temperature performance and consistency with the material test certificate.
2. 機械的特性試験
Mechanical testing verifies that the forged flange material meets specified tensile strength, 降伏強さ, elongation and hardness requirements. Test samples are taken in accordance with the relevant material specification and heat treatment condition. These checks confirm that Incoloy threaded flanges have the required strength and ductility for pressure service, thermal cycling and demanding industrial operating environments.
3. 寸法検査
Dimensional inspection covers outside diameter, 厚さ, ボア, thread accuracy, bolt hole circle, bolt hole diameter and sealing face geometry. For raised face and RTJ designs, the profile and machining finish are carefully checked to match standard tolerances. This inspection ensures fit-up compatibility with mating flanges, threaded pipe connections and specified gasket systems in field installation.
4. PMI試験と静水圧試験
Positive Material Identification is available to verify alloy grade and prevent mixed materials in critical projects. Hydrostatic or pressure-related inspection can be arranged according to project scope and applicable standards for assembled items or special requirements. SASA FLANGE 提供します EN 10204 3.1 証明書, 検査報告書, heat number traceability and other supporting documentation for export and third-party review.
