What is the difference between F51 and F53 duplex tubesheets?
F51 (2205) is a standard duplex grade, while F53 (2507) is a super duplex with higher molybdenum and chromium, offering superior corrosion resistance in seawater environments.
Can F55 tubesheets be used in high-pressure heat exchangers?
Yes. ASTM A182 F55 (Zeron 100) has very high yield strength and exceptional chloride resistance, making it ideal for high-pressure and offshore applications.
