Key Advantages

Superior Corrosion Resistance - Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC), especially in chloride-rich environments.
High Strength and Durability - Offers higher tensile strength than traditional austenitic stainless steels, with better performance in high-pressure systems.
Cost-Effective for Aggressive Environments - The combination of austenitic and ferritic phases makes this duplex steel a more affordable solution for harsh applications.
Outstanding Heat Transfer Efficiency - The tube design ensures optimal fluid flow and heat transfer, essential for efficient operation in heat exchanger applications.
Long Service Life - Superior resistance to corrosion fatigue and mechanical wear ensures long-term performance in extreme conditions.

Typical Applications

This tube is used extensively in the following heat exchanger applications:

Seawater Heat Exchangers - Ideal for marine environments or applications exposed to seawater.
Petrochemical Industry - Used in cooling systems and heat exchangers where aggressive chemical processes are involved.
Power Plants - Effective for HRSG systems and economizers in both fossil fuel and nuclear plants.
Chemical Processing Units - Effective in high-pressure chemical reactors and heat exchanger systems dealing with corrosive materials.

The 13Cr pins add some cost, but for sour service in furnaces, it's worth it. Already seeing longer run times between turnarounds compared to before.

Quality is top-tier, and the price is very competitive compared to others. Most importantly, the SA249 TP304 wall thickness is uniform and the welding looks beautiful.
