| High Light | ASTM A213 TP321 fin tubes ，extruded fin tubes for petrochemical ，Al1060 fin tubes for refineries | ||
This tube is made with a TP321 stainless steel base and Al1060 aluminum fins. TP321 stainless steel stands up well to high temperatures and corrosion, and it’s particularly durable at welded points. The aluminum fins are crafted via extrusion, forming a tight, gap-free connection with the tube. This means no heat loss from gaps or contact resistance, so heat transfers very efficiently. What’s more, aluminum fins have great thermal conductivity, boosting the overall heat dissipation effect.
It works great for chemical plant heat exchangers, waste heat recovery systems, and other scenarios that need both high-temperature stability and good heat dissipation. YUHONG can also adjust the tube size and fin design to fit your specific working conditions.

● Superior Thermal Efficiency: The Al1060 monolithic fin structure provides a continuous heat flow path. With thermal conductivity at 220–230 W/m·K, it outperforms steel fins by 5x.
● Anti-Sensitization (TP321 Advantage): Titanium stabilization ($text{Ti} ge 5 times text{C}%$) prevents intergranular corrosion during welding or high-temp service ($425^circtext{C}$–$850^circtext{C}$), where standard TP304 would fail.
● Mechanical Ruggedness: The extruded aluminum muff protects the base tube from external oxidation. Fins will not loosen, even under repeated thermal cycling or high-pressure cleaning.
● Customizable Geometry: Available in various fin pitches (FPI), heights, and tube thicknesses to optimize your Heat Recovery Steam Generator (HRSG) or Air ● Cooled Heat Exchanger (ACHE) design.
● Petrochemical & Refineries: Convection sections of vacuum heaters and crude heaters.
● Waste Heat Recovery Units (WHRU): Maximizing energy harvest from gas turbine exhaust.
● Chemical Processing: Handling aggressive media where chloride stress corrosion is a risk.
● Air Cooled Heat Exchangers (ACHE): Ideal for power plants requiring high-density cooling in compact footprints.
