What is Hastelloy C22 Washer?
Hastelloy C22 washers are high-performance corrosion-resistant washers made from Hastelloy C22, a nickel-chromium-molybdenum-tungsten alloy known for its exceptional resistance to pitting, crevice corrosion, and stress-corrosion cracking in highly aggressive chemical environments. These washers are used where extreme corrosion resistance is required, especially in mixed oxidizing and reducing media.
Applications of Hastelloy C22 Washer
- Chemical Processing – Used in reactors, piping, acid production, and systems handling chlorides, ferric/ cupric salts, and strong oxidizers.
- Pollution Control – Suitable for scrubbers, waste treatment, SO₂/NOx control systems, and corrosive flue-gas environments.
- Pharmaceutical & Biotech – Equipment exposed to aggressive cleaning chemicals and sterilizing agents.
- Oil & Gas – Ideal for sour gas, chloride-rich fluids, and offshore chemical injection systems.
- Marine & Desalination – Performs well in seawater, brine systems, and high-chloride environments.
- Laboratories & R&D – For corrosive experimental setups and pilot plants.
Common Uses of Hastelloy C22 Washer
- Washers for fastening systems in extremely corrosive chemical processing equipment.
- Used in pumps, valves, heat exchangers, and high-purity processing systems.
- Fastening hardware for equipment exposed to mixed oxidizing and reducing chemicals.
- Washers for desalination, seawater cooling systems, and high-chloride brine handling.
- Used where long-term durability in aggressive environments is essential.
- Applied in specialized chemical plants handling potent corrosive agents.
