Product Description
ASTM A213/ASME SA213 TP321/321H 1.4541/1.4878 STAINLESS STEEL SEAMLESS TUBE FOR HEAT EXCHANGER
Overview:
TP321 Seamless Tube is a type of austenitic stainless steel tube that is designed for use in high-temperature and corrosive environments. It is often used in industries such as chemical and petrochemical processing, power generation, and oil and gas production.
The TP321 grade of stainless steel is a stabilized version of 304 with added titanium, which provides enhanced mechanical properties and resistance to intergranular corrosion. The titanium effectively stabilizes the microstructure at elevated temperatures, making it more resistant to sensitization and subsequent intergranular corrosion in corrosive environments.
TP321 Seamless Tubes are seamless, meaning they are made without seams or welded joints, which ensures a high degree of structural integrity and stability. They are available in a range of sizes and can be used in various applications from small diameter tubes for instrumentation and control systems to large diameter tubes used in heat exchangers and boilers.
TP321 Seamless Tubes are also highly resistant to corrosion and are suitable for use in applications where they are exposed to corrosive fluids such as acids and alkalies. The tube's excellent corrosion resistance makes it ideal for use in high-temperature and corrosive environments.
The tubes are manufactured according to ASTM A213 and A269 standards and can be produced using a range of cold-working techniques, including cold drawing, cold rolling, and cold forging. The tubes are also commonly used in heat exchangers, boiler tubes, and other high-temperature and high-pressure applications where durability and reliability are essential.
