Incoloy 825 U tubes are specialized heat exchanger tubes constructed from Incoloy 825, a nickel-iron-chromium alloy with added copper, molybdenum, and titanium. Incoloy 825 is known for its outstanding corrosion resistance in various corrosive environments, making it a popular choice for heat exchanger applications in industries like chemical processing and marine environments.

Incoloy 825 is a nickel-based alloy that offers excellent resistance to corrosion, particularly in acidic and chloride-containing environments. Its chemical composition, which includes around 42% nickel, 22% chromium, 3% molybdenum, and 2% copper, provides superior protection against pitting, crevice corrosion, and stress-corrosion cracking. This makes Incoloy 825 U tubes suitable for use in aggressive chemical processing applications.

ASTM B163 is the specification that governs the requirements for seamless nickel and nickel alloy condenser and heat-exchanger tubes. Incoloy 825 U tubes are designed to meet these stringent standards, ensuring high-quality and reliable performance in heat exchange systems.

The outer diameter of Incoloy 825 U tubes can range from 12.70 mm to 50.80 mm, and the wall thickness varies from 0.71 mm to 5.0 mm. This range of dimensions allows for customization to meet the specific heat transfer requirements of different applications. Additionally, these tubes can be up to 24 meters long, which provides flexibility in the design and installation of heat exchangers.

Incoloy 825 U tubes are designed to meet various international specifications, including ASTM, ASME, DIN EN (German), NF (AFNOR), and JIS (Japan). This international compliance ensures their compatibility with a wide range of industries and applications worldwide, highlighting their versatility and reliability in corrosive and challenging environments.
