説明
製品詳細
Zirconium threaded flanges are internally threaded pipe flanges designed for non-welded assembly where excellent corrosion resistance is required. Compared with carbon steel and many stainless grades, zirconium offers outstanding resistance in organic acids, acetic acid, formic acid, hydrochloric service under specific controlled conditions, and other aggressive media. These flanges are commonly used in chemical plants, pharmaceutical process lines, 海洋システム, specialty reactors and high-purity service where contamination control and corrosion performance are critical.
SASA FLANGE supplies zirconium threaded flanges in standard and customized dimensions according to ASME B16.5, EN 1092-1, DIN, JIS and GB requirements where applicable. 各注文は化学分析でサポート可能, 機械的試験, 寸法検査, PMIテスト, EN 10204 3.1 certificate and full heat number traceability. カスタムドリル, special facing, non-standard thickness and project-specific marking are available on request.

製品検査
1. 化学成分検査
Chemical composition inspection verifies the zirconium grade against ASTM B564 requirements and project specifications. Spectrometric analysis checks controlled elements such as hafnium, iron, クロム, 酸素, nitrogen and residual impurities. This ensures the selected material grade is suitable for corrosive service and matches the heat number stated on the material certificate.
2. 機械的特性試験
Mechanical testing confirms that the zirconium material meets the specified tensile strength, 降伏強さ, elongation and hardness values for the ordered grade. Test samples are taken in accordance with applicable standards and reviewed against purchase requirements. These tests help verify flange integrity for assembly, pressure retention and service reliability.
3. 寸法検査
Dimensional inspection covers outside diameter, フランジの厚さ, ボルトサークル, bolt hole diameter, ハブの寸法, thread accuracy and sealing face finish. Raised face or ring joint details are checked with calibrated gauges and instruments. This inspection ensures compatibility with mating flanges, correct gasket seating and smooth installation at the job site.
4. PMI試験と静水圧試験
PMI testing is used to confirm positive material identification and prevent grade mix-up during production and packing. Hydrostatic testing can be arranged according to project requirement for assembled components or related fittings. SASA FLANGE 提供します EN 10204 3.1 証明書, inspection records and traceable marking for quality documentation and export compliance.
