ASTM A213 TP347H Serrated Finned Tube is an ultra-high-temperature heat transfer solution engineered for critical creep-resistance applications. It features a seamless niobium-stabilized austenitic stainless steel base tube (ASME SA213 TP347H) with helically wound serrated fins resistance-welded to the surface. This design delivers exceptional oxidation resistance up to 900°C (1,652°F) and prevents carbide precipitation in continuous service, making it the premier choice for superheaters, reformers, and waste heat boilers in aggressive environments.
