Lord Fin Tube-Aluminum Extruded Fin Tube

According to the heat exchange application and operation, there are various materials. The common ones are Aluminum, Alloy, Copper, Brass, Nickel, Titanium, Stainless Steel, Carbon Steel, etc, among which the aluminum and alloy are mostly used.

Aluminum Extruded Fin Tube is widely applied in barley malt, paper mill, timber drying, tobacco, food processing, coal mining, petrochemical, chemical fiber, construction materials, printing and dyeing, as more than 30 industries. Meantime, they are also complementing for equipment such as air conditioner, drying oven, drying room, air coolers and so on.

G Finned Tube

Extruded aluminum fin tube is rolled as an integrity with no thermal contact resistance, high intensity, featured in thermal shock and mechanical shock resistance. Heat exchangers assembled with this kind of fin tube (extruded fin type) is much better than the one equipped with string fin tubes or hectically wound fin tubes (L/LL/KL type fin).

Copper and aluminum com-posited fin tubes are rolled from a muff copper tube, advantaged in tight link, small thermal resistance, good heat transfer efficiency, small flow loss and strong corrosion resistance. When working in long time under heating and cooling conditions, they are durable and not easy to deform.

The integral extruded fin tubes is smooth on surface and easy to clean. When wet cooling in heating and air conditioning project, it is easy to remove the condensation water on the outer surface of the fin, and it is not easy to dust and scale in the heating and other heat exchange.

The basic performance for fin tube heat exchange should be with good solder ability and form ability, higher mechanical strength, good corrosion resistance and thermal conductivity. In spite of these, aluminum and alloy are also featured in extension and higher tensile strength increases under lower temperature. Around all world, especially for low temperature and compact heat exchange, they are widely applied.

Let’s see the feature of aluminum

1. Low Density

By alloying and heat treatment, it can reach the structural of construction steel. Suitable for various transportation, especially for small vehicle, reducing weight and consumption.

2. Good Corrosion Resistance

When under harsh conditions, the materials oxide from aluminum is non-toxic. With aluminum heat exchange, no worries that air or liquid inside will be destructed by oxide after long time.

3. Good Thermal Conductivity

Especially suitable for radiating fin, heat transfer evaporator and cond

Energy and fuels prices growth and CO2 emission restrictions, force us to use energy more efficient. Waste heat may be found in different process parts such as exhaust gas streams, or used drying process air. Using recovery heat exchanger and transferring heat into other process area is a basic method to increase production of the plant, or decrease fuel consumption.

Depending on process details, we may provide economizers with carbon steel or stainless steel materials with use of various tubes types from our portfolio.  Multi stage dry / wet systems using both - carbon steel and stainless steel elements are available to give you an optimal solution with lowest possible price. Our economizers portfolio consists solutions that will heat up water, oil, or even gas/gas recuperators.

Scope of delivery may vary depending on your process needs from heat exchangers colis only to full systems containing custom made casings with safety bypass controlled by actuator. Our engineers will help you to balance heat recovery unit with other heat exchanger that will receive recovered heat like air heater, plate, or shell and tube unit within our full equipment portfolio.
