Detalhes do produto
A tantalum blind flange is a non-bored flange designed to seal pipeline ends, válvulas, reactor nozzles and pressure equipment openings. It is selected for highly corrosive media such as hydrochloric acid, ácido sulfúrico, ácido nítrico, bromo, 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, inspeção dimensional, Teste PMI, sealing face verification and complete documentation.

Inspeção de Produto
1. Inspeção de Composição Química
Chemical composition inspection is carried out to verify tantalum purity and control residual elements such as oxygen, azoto, hydrogen and niobium within the specified range. For clad products, the backing steel chemistry is also checked against the ordered material standard. Test results are reviewed against the purchase specification and recorded in the material documentation.
2. Teste de propriedades mecânicas
Mechanical testing is performed according to the selected material condition and project requirement. A verificação típica inclui resistência à tração, força de rendimento, elongation and hardness for tantalum or for the backing material in clad construction. These tests help confirm that the flange has suitable strength, ductility and fabrication quality for safe service in demanding process systems.
3. Inspeção Dimensional
Each tantalum blind flange is inspected for outside diameter, grossura, círculo de parafuso, tamanho do furo do parafuso, 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. Teste PMI e Teste Hidrostático
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 pode fornecer EN 10204 3.1 certificado, registros de inspeção, dimensional report and traceable heat number identification.
