Tantalum flange standards include ASA/ANSI/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). Flange temperature and pressure tolerances are dependent on the rating. TREMOR ALLOYS specializes in producing high purity uniform shaped Tantalum Flanges. TREMOR ALLOYS offers custom flanges with annealed or hard tempers and will meet most of the common Milspec or ASTM standards. Tantalum flanges are circular with external ridges and varying threaded holes. In addition to standard alloys, TREMOR ALLOYS also specializes in corrosion resistant alloys, high temperature applications, and custom shapes and forms, including custom hole drill locations and threading. TREMOR ALLOYS also produces Tantalum as rod, ingot, powder, pieces, disc, granules, wire, and in compound forms, such as oxide. Flanges are often used to connect pipes or steam cylinders. Most flanges have external ridges with circular holes so screws can provide extra safety and strength.
