ASTM A249 TP304 Extruded Fin Tube is a high-integrity heat transfer solution for corrosive and high-purity applications. It features a seamless austenitic stainless steel base tube (ASTM A249 TP304) with integrally extruded aluminum fins metallurgically bonded through high-pressure thermal processing. This monolithic design eliminates interfacial resistance, achieving 98% thermal contact efficiency while providing superior chloride corrosion resistance and FDA-compliant surface finish for pharmaceutical, food processing, and chemical systems up to 260°C (500°F).
