説明
製品詳細
A tantalum blind flange is a non-bored flange designed to seal pipeline ends, バルブ, reactor nozzles and pressure equipment openings. It is selected for highly corrosive media such as hydrochloric acid, 硫酸, 硝酸, bromine, chlorides and pharmaceutical process fluids where tantalum provides outstanding resistance and long service life. Typical sealing faces include RF, FF and RTJ depending on pressure rating and gasket design.
SASA FLANGE supplies forged, machined and clad tantalum blind flanges in standard and custom dimensions. We support chemical analysis, mechanical testing of the backing material where applicable, 寸法検査, PMIテスト, sealing face verification and complete documentation. Every order can be supplied with EN 10204 3.1 証明書, full heat number traceability and customized processing according to drawings or project specifications.

These tests help confirm that the flange has suitable strength, ductility and fabrication quality for safe service in demanding process systems.
3. 寸法検査
Each tantalum blind flange is inspected for outside diameter, 厚さ, ボルトサークル, ボルト穴のサイズ, facing height, groove details where applicable and overall flatness. Sealing surfaces are visually checked for scratches, dents and machining defects. Inspection is performed in accordance with ASME, EN, DIN, JIS, GB or approved customer drawings to ensure proper fit-up during installation.
4. PMI試験と静水圧試験
PMI testing is used to confirm the supplied corrosion resistant material and avoid grade mix-up, especially for tantalum and tantalum-clad products used in critical chemical service. Hydrostatic testing is applied when required as part of assembly or project quality plans. SASA FLANGE 提供できる EN 10204 3.1 証明書, 検査記録, dimensional report and traceable heat number identification.
