2. When using Nickel 200 ANSI swing check valve, please note the following:
2.1 High-temperature limitations: Nickel 200 ANSI swing check valve will become embrittled due to grain boundary graphitization when used for extended periods above 315°C (requiring the use of low-carbon nickel such as Nickel 201).
2.2 Nickel 200 ANSI swing check valve is sensitive to oxidizing media and is not resistant to strong oxidizing acids such as nitric acid and concentrated sulfuric acid.
3 Conclusion:
3.1 The core value of Nickel 200 ANSI swing check valve lies in their purity and basic corrosion resistance, making them suitable for non-extremely oxidizing/high-temperature corrosive environments.
3.2 The core value of Nickel 200 ANSI swing check valve in the chemical industry lies in the "reducing media + high purity requirements" scenario, making them a benchmark material for handling caustic soda, fluorides, and organic acids.
4. Typical Applications of Freeman Valve's Nickel 200 ANSI swing check valve:
4.1 Freeman Valve's Nickel 200 ANSI swing check valve is widely used in caustic soda (NaOH/KOH) production and processing, such as in evaporators, molten caustic soda transfer piping, and reactor linings. In high-temperature, high-concentration caustic solutions (≤50% NaOH, ≤300°C), Nickel 200 ANSI swing check valve offer excellent corrosion resistance, preventing stress corrosion cracking (compared to stainless steel).
4.2 Freeman Valve's Nickel 200 ANSI swing check valve is widely used in organic chemical processing (fatty acid and phenol production), such as in reactors, distillation columns, and condensers. Nickel 200 ANSI swing check valve is resistant to organic acids (such as acetic acid and oleic acid) and organic solvents, ensuring purity and preventing product contamination.
4.3 Freeman Valve's Nickel 200 ANSI swing check valve is widely used in the chlor-alkali industry, including equipment such as chlorine drying towers, brine heaters, and electrode assemblies. Nickel 200 ANSI swing check valve is resistant to corrosion from wet chlorine, hypochlorite, and high-temperature salt water (oxidizing acids should be avoided).
4.4 Freeman Valve's Nickel 200 ANSI swing check valve is widely used in hydrofluoric acid (HF) and fluoride processing applications, such as HF storage tanks, fluorination reactors, and pickling equipment. Nickel 200 ANSI swing check valve is extremely resistant to fluoride ion corrosion (superior to most stainless steels).
4.5 Freeman Valve's Nickel 200 ANSI swing check valve is widely used in sulfuric and hydrochloric acid environments (non-oxidizing conditions), such as dilute sulfuric acid (<60%) storage tanks, hydrochloric acid heat exchangers, and acid pump components. However, Nickel 200 ANSI swing check valve is not suitable for concentrated sulfuric acid (>70%) or mixed acids containing oxidants (such as HNO₃).
4.6 Freeman Valve's Nickel 200 ANSI swing check valve is widely used in salt solution processing applications, such as ammonium chloride and nickel sulfate crystallization equipment, and salt dryers. Nickel 200 ANSI swing check valve is resistant to halide stress corrosion, but pitting corrosion should be avoided.
