ASME SA213/ASTM A213 This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T5, TP304, etc.

The A213 TP304 tube is a reliable and efficient component in heat exchangers, offering excellent corrosion resistance, durability, and heat transfer capabilities. Its versatility and low maintenance requirements make it a preferred choice in various industries, ensuring efficient and long-lasting performance in heat exchange applications.

Key Features Suitable For Heat Exchangers

The A213 TP304 tube plays a crucial role in heat exchangers due to its material properties and design.

TP304 material contains 18% chromium and 8% nickel, making it highly resistant to corrosion. This is particularly important in heat exchangers where the tubes are exposed to various fluids, including water, chemicals, and gases, which can be corrosive.

TP304 maintains its strength and structural integrity at high temperatures, which is essential for heat exchangers operating in high-temperature environments.

Stainless steel material is durable and can withstand the mechanical stresses and thermal cycling that occur in heat exchangers.

The smooth internal and external surfaces of TP304 tubes help in reducing the buildup of deposits and scaling, which can impede heat transfer.

TP304 is compatible with a wide range of fluids, including water, steam, oils, and many chemicals. This makes it versatile for use in different types of heat exchangers, such as shell-and-tube, plate, and finned-tube heat exchangers.

Applications In Heat Exchangers

Food and Beverage Industry

Due to its corrosion resistance and ease of cleaning, TP304 is also used in heat exchangers in the food and beverage industry, where hygiene and cleanliness are critical.

Industrial Heat Exchangers

TP304 tubes are commonly used in industrial heat exchangers for processes such as power generation, chemical processing, and oil refining.

HVAC Systems

They are also used in heating, ventilation, and air conditioning (HVAC) systems, where they help in transferring heat between air and water or other fluids.
