ASTM A213 TP321 Stainless Steel Seamless Tube For Heat Exchanger
ASTM A213 TP321 is a standard specification for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. It specifically covers seamless stainless steel tubes for high-temperature and corrosive service.
TP321 is a grade of stainless steel that contains titanium, which provides enhanced resistance to intergranular corrosion. This grade is commonly used in applications where high-temperature strength and resistance to oxidation are required.
The seamless tubes manufactured under this specification are typically used in heat exchangers, boilers, and superheaters in various industries such as chemical, petrochemical, power generation, and oil and gas.
The ASTM A213 TP321 stainless steel seamless tubes are produced by either hot or cold working methods. They are annealed and pickled to remove any scale or oxide formation on the surface. The tubes are then subjected to various tests and inspections to ensure their quality and compliance with the specified requirements.
Some of the key properties of ASTM A213 TP321 stainless steel seamless tubes include excellent corrosion resistance, high strength at elevated temperatures, good weldability, and formability. These tubes are designed to withstand high-pressure and high-temperature environments, making them suitable for use in heat exchangers.
In summary, ASTM A213 TP321 stainless steel seamless tubes are used in heat exchangers for their excellent corrosion resistance, high-temperature strength, and resistance to oxidation. They are manufactured to meet specific requirements and undergo rigorous testing to ensure their quality and performance.
