Scrubber Vessel (Alloy 20)
The Alloy 20 scrubber vessel is built from a nickel–iron–chromium austenitic alloy that is developed for chemical processing applications requiring superior corrosion resistance and mechanical reliability. Its combination of chemical stability, strength, and cleanability makes it a reliable choice for demanding scrubbing processes in chemical, pharmaceutical, and food-related industries.
Advantages
- Strong corrosion resistance: Excellent resistance to uniform corrosion, pitting, and crevice attack in chloride-containing media, as well as in sulfuric, phosphoric, nitric, and other aggressive acids and salts.
- Resistance to stress corrosion cracking: With balanced chromium, nickel, and molybdenum content, Alloy 20 demonstrates outstanding performance against chloride-induced stress corrosion cracking, ensuring vessel integrity in harsh conditions.
- Reliable mechanical properties: High strength, toughness, and ductility make it suitable for forming and machining into a variety of vessel shapes, while maintaining stability across both low and elevated temperatures.
- Good fabrication and welding performance: Minimal carbide precipitation during welding simplifies manufacturing and makes installation and maintenance easier.
- Compliance with hygiene standards: Meets international standards such as FDA (U.S. Food and Drug Administration) certification, allowing safe use in processes involving contact with food, pharmaceuticals, and other sensitive products without risk of contamination.
