Product Description

I. Product Overview

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.

IV. Comparison: TP321 Extruded Aluminum Fin Tube vs. TP304

Feature	TP321	TP304
High-Temp Stability	No sensitization after welding	Risk of "Weld Decay"
Corrosion Type	Resists Intergranular Corrosion	Prone to Carbide Precipitation
Welding Integrity	No sensitization after welding	Risk of "Weld Decay"
Service Life	Longer in cyclic thermal environments	Shorter in high-temp corrosive gas
Cost	Higher (Due to Titanium alloying)	Lower (Economy grade)
Best For	Petrochemical, Refineries, WHRU	Food grade, Mild chemicals, HVAC

V. Why Choose TP321 + Al1060 Extruded Fin Tubes?

● 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.

Ⅵ. Key Applications

● 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.

It's hot and humid here, and our old wrap-on tubes used to rust like crazy. Switched to your extruded ones—the aluminum fin covers the steel pipe perfectly, so corrosion shouldn't be an issue.

Tube ends were clean, dimensions accurate. Our fitters didn't complain about fit-up.

Quality is top-tier, and the price is very competitive compared to others. Most importantly, the SA249 TP304 wall thickness is uniform and the welding looks beautiful.
