Tantalum - flange

I. Product Introduction Tantalum flanges are corrosion-resistant pipe fittings made from high-purity tantalum (Ta1/Ta2) or tantalum-tungsten alloy through forging, machining, precision turning, pickling, and polishing. They possess extremely high chemical stability, high temperature resistance, non-magnetic properties, and excellent sealing performance, making them a high-end flange fitting replacement for stainless steel, titanium, and ordinary alloys in highly corrosive environments.

Material Grades: (R05200/R05400), Ta2.5W, Ta10W
Density: 16.7 g/cm³
Melting Point: 2996℃
Standards: Compliant with HG, GB, ANSI, JIS, DIN Standard processing available

Structure types: Flat-face flanges, weld neck flanges, neck flanges, blind flanges, custom-made flanges

Surface finishes: Machined, pickled and passivated, polished

II. Product Features

Superior corrosion resistance: Resistant to hydrochloric acid, nitric acid, dilute sulfuric acid, aqua regia, organic acids, and strong alkalis at room temperature; extremely low corrosion rate.

High-temperature creep resistance: Not easily deformed at medium and high temperatures; long-lasting and stable sealing performance.

High strength and good sealing performance: High machining precision, smooth end face, suitable for high-pressure and high-vacuum systems.

Non-toxic and biocompatible: Non-magnetic, does not pollute the medium, suitable for pharmaceuticals, food, and fine chemicals.

Weldable and assemblable: Excellent welding performance with tantalum pipes and tantalum equipment; strong assembly compatibility.

III. Main Application Areas
Strongly corrosive chemicals Industry Applications: Piping systems for hydrochloric acid, organic acids, and chloride media; flanges for chemical reactors, heat exchangers, towers, and tantalum equipment; corrosion-resistant piping flanges for electroplating, pickling, and environmental exhaust gas treatment; pharmaceuticals, fine chemicals, and food; high-purity material conveying and aseptic process piping connections; sanitary flanges that are free of metal contamination, corrosion-resistant, and easy to clean; vacuum and electronic semiconductors; flanges for high-vacuum equipment, coating equipment, and high-temperature furnace chambers; corrosion-resistant sealing flanges for high-purity fluid conveying systems; aerospace, military, and special equipment; piping systems for high-temperature, corrosive, and high-pressure special operating conditions; tantalum flange assemblies for high-precision instruments and testing equipment; laboratory and pilot-scale equipment; piping connections for highly corrosive experimental fluids; custom tantalum flanges and blind flanges for small-scale/pilot-scale equipment.
