Tantalum threaded flanges are internally threaded flanges used to connect threaded pipe or fittings without welding, making them suitable for highly corrosive media, small-bore piping and installations where hot work must be avoided. Tantalum offers outstanding resistance to strong acids and exceptional performance in demanding chemical, фармацевтический, semiconductor and specialty processing systems. These flanges are commonly produced with raised face or flat face sealing surfaces for compact, leak-resistant connections.
SASA FLANGE supplies tantalum threaded flanges in standard and custom dimensions according to ASME B16.5 и требования к проекту. Each order can be supported with chemical analysis, механические испытания, проверка размеров, Тестирование PMI, EN 10204 3.1 certificate and full heat number traceability. Customized drilling, лицом к лицу, special thread forms and non-standard sizes are available for OEM and EPC applications.

2. Испытание механических свойств
Mechanical properties testing checks tensile strength, предел текучести, elongation and hardness of the tantalum material condition used for flange machining. These tests confirm that the material has adequate ductility and strength for assembly and service. Test results are reviewed against the applicable specification and can be included in the material certification package.
3. Проверка размеров
Dimensional inspection covers outside diameter, толщина, бурить, размеры ступицы, bolt hole circle, размер отверстия для болта, sealing face profile and thread accuracy. For threaded flanges, special attention is paid to thread type and fit such as NPT or BSP. This inspection ensures interchangeability with mating components and reliable field installation.
4. PMI-тестирование и гидростатические испытания
PMI testing is used to confirm the supplied flange material matches the ordered tantalum grade and maintain positive identification through production. Hydrostatic testing can be arranged as part of assembled system verification or project-specific inspection.
