ASTM A-789 Stainless Steel Seamless High Precision & Heat Exchanger Tubes

Stainless Steel Seamless High Precision & Heat Exchanger Tubes

Manufacturers of ASTM A-789 Stainless Steel Seamless High Precision & Heat Exchanger Tubes

Our ASTM A-789 Stainless Steel Seamless High Precision & Heat Exchanger Tubes are manufactured to the highest quality standards, designed for optimal performance in heat exchangers, condensers, boilers, and other critical heat transfer applications. These tubes are made from austenitic and duplex stainless steel alloys, specifically engineered to provide excellent resistance to pitting, crevice corrosion, and oxidation in harsh environments.

ASTM A-789 covers both seamless and welded tubes, offering superior mechanical properties such as high tensile strength, resistance to high-temperature oxidation, and excellent corrosion resistance in aggressive media, including acidic and chloride-rich environments. These tubes are commonly used in industries such as chemical processing, petrochemical, power generation, and marine applications, where durability and high performance are essential.

The seamless construction ensures uniform wall thickness, high-pressure resistance, and excellent structural integrity, while the precision manufacturing process results in smooth internal surfaces that optimize heat transfer efficiency and fluid dynamics.

Available in a variety of sizes and customizable grades, our ASTM A-789 Stainless Steel Seamless High Precision & Heat Exchanger Tubes are designed to provide reliable, long-lasting performance in even the most demanding industrial applications.
