製品検査
1. 化学成分検査
Chemical analysis is performed to confirm that the supplied Incoloy material meets the specified alloy grade such as 800H or 825. Key elements including nickel, クロム, モリブデン, titanium and copper are checked against the relevant standard. This inspection helps ensure corrosion resistance and material consistency before machining and shipment.
2. 機械的特性試験
機械試験により引張強度を検証, 降伏強さ, elongation and hardness of the flange material in accordance with the applicable material specification. These tests confirm that the alloy has the required structural performance for pressure-containing piping systems. Test results are reviewed together with heat treatment records and included in project quality documents when specified.
3. 寸法検査
Dimensional inspection covers outside diameter, 厚さ, ボア, ボルトサークル, bolt hole diameter, number of holes and flange facing details. For lap joint flanges, fit-up compatibility with the stub end is especially important. SASA FLANGE checks dimensions against ASME, EN, DIN, JIS, GB or approved drawings to ensure proper installation on site.
4. PMI試験と静水圧試験
Positive Material Identification is conducted to verify the alloy grade and prevent material mix-up in critical service environments. Hydrostatic testing can be arranged where project specifications require pressure integrity verification for assembled components or related flange systems. EN 10204 3.1 証明書, inspection records and traceability documents are supplied according to order requirements.
