ASME Section VIII Certified SA790 S32205 Duplex U-Bend Heat Exchanger Tube Bundle Sulfide Resistance
Yuhong Holdings Group Co., Ltd. is a specialized manufacturer of pressure vessels, with an annual production capacity exceeding 6,000 tons. We provide a wide range of high-quality products, including film evaporators, heat exchangers, reaction vessels, towers, storage tanks, and filters.
Advantages of SA790 S32205 Duplex U-Bend Heat Exchanger Tube Bundle
SA790 S32205 is a duplex stainless steel known for its excellent corrosion resistance and high strength, making it ideal for high-temperature and high-pressure environments. Key benefits include:
SA790 S32205 Duplex U-Bend Heat Exchanger Tube Bundle Pitting Resistance Equivalent
PRE (Pitting Resistance Equivalent) quantifies resistance to localized corrosion in chloride-rich environments. The formula is:
PRE = %Cr + 3.3 × %Mo + 16 × %N
For S32205 duplex steel:
PRE ≥ 22 + 3.3×3 + 16×0.14 = 33.24, with typical values ≥35
