Product Description

Premium Duplex Stainless Steel Heat Exchange Tubes for Custom Orders
Premium Duplex Stainless Steel Heat Exchange Tubes for Custom Orders
Stainless Steel Heat Exchange Pipe/Tube
Stainless steel heat exchanger tubes are precision-engineered components designed for optimal thermal transfer in demanding environments. Manufactured primarily from grades such as 304/304L, 316/316L, and duplex steels, these tubes leverage stainless steel's inherent corrosion resistance, high-temperature strength, and excellent mechanical properties to ensure long-term reliability and performance.
The tubes are produced to strict dimensional tolerances (e.g., ASTM A213, ASME SB-163) via seamless or welded and cold-drawn processes, resulting in smooth inner and outer surfaces that minimize fouling and maximize heat transfer efficiency. Common configurations include U-tubes, straight lengths, and coiled designs, available in a wide range of diameters and wall thicknesses.
Key advantages include outstanding resistance to oxidation, chloride stress corrosion, and organic/media corrosion; superior cleanliness for hygienic applications; and robust performance under high pressure and thermal cycling. They are widely used in shell-and-tube, plate, and air-cooled exchangers across industries like chemical processing, oil & gas, power generation, HVAC, marine, and food & pharmaceutical.
Customization in material grade, size, finish, and testing (hydrostatic, eddy current, ultrasonic) is available to meet specific thermal, pressure, and environmental requirements. These tubes offer a dependable, low-maintenance solution for critical heat transfer tasks.
