Detalle del producto
A tantalum blind flange is a non-bored flange designed to seal pipeline ends, valvulas, 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, inspección dimensional, Pruebas del PMI, sealing face verification and complete documentation. Every order can be supplied with EN 10204 3.1 certificado, full heat number traceability and customized processing according to drawings or project specifications.

Inspección del producto
1. Inspección de composición química
Chemical composition inspection is carried out to verify tantalum purity and control residual elements such as oxygen, nitrógeno, 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. Pruebas de propiedades mecánicas
Mechanical testing is performed according to the selected material condition and project requirement. Typical verification includes tensile strength, límite elástico, 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. Inspección dimensional
Each tantalum blind flange is inspected for outside diameter, espesor, círculo de pernos, tamaño del agujero del perno, 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. Pruebas PMI y pruebas hidrostáticas
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 puede proporcionar EN 10204 3.1 certificado, registros de inspección, dimensional report and traceable heat number identification.
