Ürün Detayı
A tantalum blind flange is a non-bored flange designed to seal pipeline ends, vanalar, reactor nozzles and pressure equipment openings. It is selected for highly corrosive media such as hydrochloric acid, sülfürik asit, nitrik asit, 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, boyutsal muayene, PMI testi, sealing face verification and complete documentation. Every order can be supplied with EN 10204 3.1 sertifika, full heat number traceability and customized processing according to drawings or project specifications.
