Alloy 20 Pipe Fittings (UNS N08020 | 2.4660) - Emirerri

Alloy 20 Pipe Fittings (UNS N08020) with superior sulfuric acid resistance. ASTM B366 buttweld & forged fittings in all sizes and types.

Alloy 20 Pipe Fittings are premium corrosion-resistant fittings made from Alloy 20 (UNS N08020 / 2.4660) — a high-performance nickel-iron-chromium alloy stabilized with niobium to prevent sensitization and intergranular corrosion. These fittings are engineered to provide exceptional resistance to sulfuric acid, chlorides, pitting, crevice corrosion, and stress-corrosion cracking, while maintaining excellent mechanical strength and thermal stability in aggressive environments.

Manufactured to international standards such as ASTM B366 / ASME SB366, Alloy 20 pipe fittings come in a wide range of types and sizes, including elbows (45°, 90°, 180°), tees (equal/reducing), reducers (concentric/eccentric), caps, stub ends, crosses, and forged fittings like couplings, unions, and nipples. They are available in seamless, welded, and fabricated forms with dimensions conforming to ASME B16.9, B16.28, and MSS-SP-43.

Thanks to their superior resistance to corrosive media — particularly sulfuric, phosphoric, and nitric acids — and robust fabrication properties, Alloy 20 fittings are ideal for demanding applications in chemical processing, petrochemical, pharmaceutical, food and beverage processing, power generation, marine, and offshore systems.

Nickel 200 Pipe Fittings (UNS N02200) are high-performance fittings manufactured from commercially pure wrought nickel (≥ 99 % Ni), known for outstanding corrosion resistance, ductility, and thermal/electrical conductivity. These fittings are made to ASTM B366 / ASME SB366 standards and are suitable for severe corrosive and high-temperature environments where reducing media and alkalis are present.

Nickel 200 fittings maintain excellent mechanical strength and stability across broad temperature ranges and are ideal for use in chemical processing, marine engineering, petrochemical, food processing, aerospace, and industrial piping systems. With superior formability, weldability, and fabrication characteristics, they are available in a variety of configurations such as elbows (45°, 90°, 180°), tees, reducers (concentric & eccentric), caps, stub ends, and crosses to fit diverse pipeline requirements.

These fittings resist caustic alkalis, neutral salts, distilled and natural waters, and reducing environments, ensuring long-term reliability and low maintenance in critical applications.
