1. What is Incoloy 825?
Incoloy 825 is a high-performance nickel-iron-chromium alloy with excellent corrosion resistance to oxidizing acids (such as nitric acid), reducing acids (such as sulfuric acid and phosphoric acid), chloride environments, and sulfide environments. Its mechanical properties remain stable over a temperature range of room temperature to 550°C.
2. Advantages of Freeman Valve's Incoloy 825 Basket type strainer:
2.1 Freeman Valve's Incoloy 825 basket type strainer exhibit excellent corrosion resistance to oxidizing acids (such as nitric acid) and reducing acids (such as sulfuric acid and phosphoric acid), especially performing exceptionally well under medium-concentration sulfuric acid and phosphoric acid conditions at low and medium temperatures;
2.2 Freeman Valve's Incoloy 825 basket type strainer possess strong resistance to chloride corrosion, effectively resisting pitting corrosion, crevice corrosion, and stress corrosion cracking (SCC), making them suitable for chlorinated seawater, brine, and chemical media environments;
2.3 Freeman Valve's Incoloy 825 basket type strainer is resistant to sulfide corrosion and can be used in acidic oil and gas wells in the oil and gas industry, resisting sulfide stress cracking (SSC);
2.4 Freeman Valve's Incoloy 825 basket type strainer maintain stable strength and ductility within a temperature range of room temperature to 550°C, and also possess good toughness at low temperatures, without low-temperature brittleness;
2.5 Freeman Valve's Incoloy 825 basket type strainer has excellent weldability;
2.6 Freeman Valve's Incoloy 825 basket type strainer effectively prevent intergranular corrosion due to the addition of titanium, which combines with carbon to form carbides, preventing the precipitation of chromium carbides at grain boundaries. This makes them particularly suitable for applications where post-weld solution treatment is not possible.
3. Classic Applications of Freeman Valve's Incoloy 825 Basket type strainer:
3.1 Wet-Process Phosphoric Acid Production: Freeman Valve's Incoloy 825 basket type strainer is advantageous in wet-process phosphoric acid production due to their resistance to medium-low temperature, medium-concentration phosphoric acid corrosion, resistance to chloride/fluoride ion pitting and stress corrosion, and the elimination of post-treatment requirements for welded joints;
3.2 Phosphoric Acid-Based Fertilizer Production: Freeman Valve's Incoloy 825 basket type strainer is the preferred material for the production of ammonium phosphate (MAP/DAP);
3.3 Metal Pickling and Surface Treatment: Freeman Valve's Incoloy 825 basket type strainer is crucial control units in sulfuric acid pickling lines, capable of withstanding accumulated metal ions (Fe²⁺/Fe³⁺) and chlorides in the acid solution;
3.4 Hydrometallurgy: Freeman Valve's Incoloy 825 basket type strainer can handle complex acidic solutions in the leaching, extraction, and electrowinning processes of copper, zinc, cobalt, and nickel;
3.5 Waste Acid Regeneration: Freeman Valve's Incoloy 825 basket type strainer has been widely used in process equipment for recovering sulfuric acid from waste acid.
