ASME SA798 S32205 Duplex Stainless Steel Tube U for Heat Exchanger ASME U STAMP

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.

Product Description

The U-tube heat exchanger tubes made of S32205 duplex stainless steel are engineered for demanding applications such as stripper reboilers. S32205 (UNS S32205) offers exceptional corrosion resistance, particularly against chloride-induced stress corrosion cracking (SCC), pitting, and crevice corrosion, making it ideal for aggressive environments containing acids, brines, or H2S.

With a balanced microstructure of austenite and ferrite, these tubes deliver high mechanical strength (minimum tensile strength 620 MPa) and excellent fatigue resistance, ensuring durability under cyclic thermal and pressure loads.

Compliant with ASTM A789/A790 standards, the U-bend design maximizes heat transfer efficiency while minimizing stress concentration. Suitable for oil/gas, chemical, and marine industries, these tubes provide long-term reliability in high-temperature, high-pressure, and corrosive service conditions.
