ASTM A213 TP304 Boiler Tube Advantages
ASTM A213 is a standard developed by the American Society for Testing and Materials for seamless ferritic and austenitic alloy steel tubes for boilers, superheaters and heat exchangers.
ASTM A213 TP304 heat exchanger tubes are formed by hot extrusion process, with no internal weld structure, higher pressure bearing capacity (maximum 24-inch tube diameter), low absolute roughness of the inner wall (≤0.05mm), reducing fluid resistance, improving heat exchange efficiency, especially suitable for precision instruments and high-purity media transmission.
ASTM A213 TP304 stainless steel boiler tubes can withstand extreme temperature ranges from -196°C to 800°C, and still maintain stable mechanical properties at high temperatures, meeting the long-term operation requirements of high-temperature equipment such as boilers and superheaters.

What is the difference between TP304 and 304L heat exchanger tubes?
Carbon content: TP304 carbon ≤ 0.08%, 304L carbon ≤ 0.03%, the latter has stronger resistance to intergranular corrosion after welding.
Application scenario: 304L is suitable for highly corrosive environments containing Cl⁻ (such as seawater desalination heat exchangers).
GNEE supplies TP304 stainless steel seamless pipes that comply with international standards such as ASTM A213, ASME SA213, and EN 10216-5. They come with ultrasonic testing reports, hydrostatic testing (twice the working pressure held for 10 minutes), and SGS material analysis. The designed service life exceeds 15 years, and the maintenance cost is 60% lower than that of carbon steel.
