製品検査
1. 化学成分検査
Chemical composition inspection is carried out to confirm the chromium, ニッケル, 炭素, manganese, シリコン, phosphorus and sulfur levels meet ASTM A182 F310 or F310S requirements. Positive laboratory analysis or spectrometer testing is used to verify the heat chemistry before production release, ensuring the supplied threaded flanges match the ordered stainless steel grade.
2. 機械的特性試験
Mechanical testing is performed on representative material to verify tensile strength, 降伏強さ, elongation and hardness in accordance with the applicable forging standard. This confirms that 310 stainless steel threaded flanges provide the required basic strength and ductility for pressure piping service, while maintaining consistency across each manufacturing heat and production lot.
3. 寸法検査
Dimensional inspection includes outside diameter, 厚さ, ハブの寸法, flange facing, ボルトサークル, bolt hole alignment and internal thread accuracy. For threaded flanges, thread profile and engagement are especially important to ensure correct fit with matching threaded pipe. Inspection is conducted against ASME, EN, DIN, JIS, GB or approved customer drawings.
4. PMI試験と静水圧試験
PMI testing is available to verify the alloy grade of each flange using handheld XRF or equivalent equipment, which is important for mixed-material project control. Hydrostatic testing can be arranged when required by project specification or assembly condition. SASA FLANGE also provides EN 10204 3.1 証明書, inspection records and full heat number traceability.
