ASTM A213 TP304H Serrated Finned Tubes With Stainless Steel Fins For Heat Furnaces

ASTM A213 TP304H Serrated Finned Tubes With Stainless Steel Fins For Heat Furnaces

ASTM A213 is a standard specification issued by the American Society for Testing and Materials, covering seamless ferritic and austenitic alloy steel tubes for high-temperature service. These tubes are engineered for applications involving elevated temperatures, corrosion resistance, and structural integrity, widely adopted in petrochemical, power generation, and oil & gas industries.

ASTM A213 TP304H serrated finned tubes with stainless steel fins are a high-performance solution specifically engineered for severe duty in heat furnaces and other high-temperature applications.

TP304H The higher carbon provides significantly improved high-temperature strength (creep strength) compared to standard TP304 or TP304L. This is essential for components operating under stress at temperatures above ~525°C (977°F), such as in furnace convection sections.

In industrial furnace systems, stainless steel serrated finned tubes serve as core heat transfer enhancement components, whose primary function is to improve the heat exchange efficiency between the flue gas inside the furnace and the medium within the tubes (e.g., thermal oil, water, steam or process fluids). Meanwhile, relying on the high temperature resistance and corrosion resistance of stainless steel, these tubes are suitable for the high-temperature and corrosive flue gas working conditions of industrial furnaces.

Key Features 

Excellent High-Temperature Strength: The TP304H base tube is designed to withstand the internal pressure of water, steam, or process fluid at high furnace temperatures without creep failure.

Superior Oxidation & Corrosion Resistance: Both tube and fins resist oxidation (scaling) from hot flue gases and corrosion from condensates or sulfur compounds.

Enhanced Heat Transfer: The serrated fin design maximizes the heat recovery from flue gases, improving furnace efficiency and fuel economy. 

Long Service Life: The combination of material and design leads to reduced fouling, lower maintenance, and longer intervals between tube bundle replacements.
