Freeman Valve's Nickel 200 DIN Y type strainer offers the following advantages:
1.1 Excellent Corrosion Resistance:
a. Freeman Valve's Nickel 200 DIN Y type strainer offer excellent resistance to reducing acids (such as hydrochloric acid and sulfuric acid), alkaline solutions, and saline media.
b. Freeman Valve's Nickel 200 DIN Y type strainer is stable in dry halogens (such as chlorine and fluorine) and high-temperature, non-oxidizing environments.
1.2 Excellent Mechanical Properties:
Freeman Valve's Nickel 200 DIN Y type strainer maintain strength and ductility at low to medium temperatures (-250°C to +300°C).
1.3 High Purity:
Freeman Valve's Nickel 200 DIN Y type strainer have a nickel content of ≥99.0% and is low in impurities, making them suitable for applications requiring high cleanliness (such as the food and nuclear industries).
2. When using Nickel 200 DIN Y type strainer, please note the following:
2.1 High-temperature limitations: Nickel 200 DIN Y type strainer 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 DIN Y type strainer 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 DIN Y type strainer 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 DIN Y type strainer 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 DIN Y type strainer:
4.1 Freeman Valve's Nickel 200 DIN Y type strainer 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 DIN Y type strainer offer excellent corrosion resistance, preventing stress corrosion cracking (compared to stainless steel).
4.2 Freeman Valve's Nickel 200 DIN Y type strainer is widely used in organic chemical processing (fatty acid and phenol production), such as in reactors, distillation columns, and condensers. Nickel 200 DIN Y type strainer 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 DIN Y type strainer is widely used in the chlor-alkali industry, including equipment such as chlorine drying towers, brine heaters, and electrode assemblies. Nickel 200 DIN Y type strainer 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 DIN Y type strainer is widely used in hydrofluoric acid (HF) and fluoride processing applications, such as HF storage tanks, fluorination reactors, and pickling equipment. Nickel 200 DIN Y type strainer is extremely resistant to fluoride ion corrosion (superior to most stainless steels).
4.5 Freeman Valve's Nickel 200 DIN Y type strainer 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 DIN Y type strainer is not suitable for concentrated sulfuric acid (>70%) or mixed acids containing oxidants (such as HNO₃).
4.6 Freeman Valve's Nickel 200 DIN Y type strainer is widely used in salt solution processing applications, such as ammonium chloride and nickel sulfate crystallization equipment, and salt dryers. Nickel 200 DIN Y type strainer is resistant to halide stress corrosion, but pitting corrosion should be avoided.
