What media are extruded finned tubes suitable for? Can they be used in corrosive gas systems?

Extruded finned tubes are highly efficient heat transfer components widely used across various thermal systems. Thanks to the integrated mechanical extrusion process, the fins and base tube form a solid, durable structure with excellent thermal conductivity and mechanical stability. These tubes are suitable for a broad range of both liquid and gaseous media, especially in high-pressure, high-temperature, and corrosive environments.

Commonly handled media include:

• Water, steam, thermal oil

• Air, nitrogen, natural gas

• Flue gas, exhaust gas, high-temperature gas streams

• Ammonia, hydrogen sulfide, urea vapor, and corrosive gas mixtures

• Seawater, brine, and other corrosive liquids

Can extruded finned tubes be used in corrosive gas systems?
Absolutely — provided the materials are properly selected:

• Core tube materials can be carbon steel (e.g., ASTM A210/A192), stainless steel (e.g., TP316L, S2205), copper-nickel alloys, or titanium to meet different corrosion resistance requirements.

• Fin materials can be aluminum alloy, copper, or stainless steel to further enhance chemical resistance.

Extruded finned tubes are widely used in highly corrosive environments such as seawater desalination plants, chloride gas condensers, and ammonia cooling systems — proving their exceptional adaptability and reliability under aggressive operating conditions.
