Single metal Finned Tube and double metal composite finned tube
The single-metal finned tube is integrally rolled from an aluminum tube, has no contact thermal resistance, high strength, heat and mechanical vibration resistance, good thermal expansion performance, and has a considerable extended heat transfer surface. The Heat Exchanger made of this finned tube is a heat exchanger with a wide range of uses. Bimetal composite Finned Tubes are made of copper and aluminum tubes (or steel tubes, aluminum tubes; or Stainless steel tubes, aluminum tubes) after compounding and then rolling out fins, which have tight combination, small thermal resistance, good heat transfer performance, and high strength. , small flow loss, strong anti-corrosion performance, not easy to deform under long-term cold and hot conditions, and long working life.
The overall rolled fin has no burr, no wrinkle, Easy To Clean , easy to remove condensed water on the outer surface of the fin during wet cooling in heating and air conditioning engineering, and not easy to dust and scale in drying heating and other heat exchange occasions. The aluminum rolled finned tubes and bimetallic composite finned tubes produced by our factory. The surface is anodized, the color is beautiful and generous, and it can effectively prevent surface corrosion.
High Quality Spiral Finned Tube
Specializing in the production of single and double-metal steel-aluminum composite Finned Tubes, welcome to customize the detailed description:
Single and double-metal steel-aluminum composite Finned Tubes Aluminum rolled finned tubes are rolled from aluminum tubes as a whole, with no contact thermal resistance, high strength, thermal shock resistance and mechanical vibration resistance, good thermal expansion performance, and considerable expansion change. The hot surface, the heat exchanger made of this finned tube, is more effective than the serial fin or wound fin heat exchanger. Copper-aluminum composite finned tubes are copper and aluminum tubes that are laminated and then rolled out of fins. They have the advantages of tight combination, small thermal resistance, good heat transfer performance, high strength, small flow loss, and Strong Corrosion Resistance.
It is not easy to deform under working conditions and has a long working life. The overall rolled fins are smooth and free of burrs, no wrinkles, easy to clean, easy to remove condensed water on the outer surface of the fins during wet cooling in heating and air-conditioning projects, and Not Easy To Accumulate Dust and scale in drying heating and other heat exchange occasions. The aluminum-rolled finned tubes and copper-aluminum composite finned tubes produced by our factory are all anodized on the surface, and the color is beautiful and generous, which can effectively prevent surface corrosion. Our factory can also process steel winding finned tubes and steel-aluminum composite finned tubes according to the needs of users.

1. Rao Finned Tube
Wound Finned Tubes are all made of (steel, aluminum, copper, stainless steel, etc.) tape wound (steel, aluminum, copper, stainless steel, etc.) tubes, after
High Quality Spiral Finned Tube
Mechanically strong wound, helical, with three different pitches: 3.2mm "R", 4.2mm "M", 6.5mm "T".
R film distance, small film distance and large heat dissipation area, with large heat dissipation;
M chip distance, the larger the chip distance, the smaller the heat dissipation and air resistance;
T sheet distance, suitable for the situation of high steam pressure and low air temperature rise.
2. Extruded (rolled sheet) finned tube
Rolled finned tube fins are smooth, burr-free, wrinkle-free, beautiful and bright, and easy to clean. When used as components of air heaters and surface coolers, it is easy to remove surface condensation water, and it is not easy to accumulate dust and condensation in drying and heating and other occasions. Scale, rolled finned tube fins cross-section and trapezoidal, so the fins have high strength, and expand the heat dissipation surface, so that the material can be used to the greatest extent.

Finned Tube Heat Exchanger adopts the method of adding finned tube heat exchanger, which greatly improves the heat emission of radiator fins and further improves the role of heat emission of radiator fins. The finned tube heat exchanger is welded with low-carbon environment-friendly steel pipes, which is durable and emits heat for a long time. Our inspection and maintenance during use are still helpful to the service life of radiator fins.
About Finned Tubes
Laser Welded Finned Tubes in which the fins (solid or serrated) are helically wound and continuously welded to the tube by a fully automatic laser fin machine. Produced in strict accordance with enterprise standards, with sophisticated technology, excellent performance, lower heat input, and improved heat flow efficiency and corrosion resistance.
A finned tube is a tube with many fins around the outer surface. These fins act as filters and mechanisms to transfer heat from the material inside the tube to the outside space and vice versa. Finned Tubes are used in applications that require the transfer of heat from a hot fluid to a cooler fluid through the tube walls.

♦ Extruded Finned Tube
♦ High Frequency Welded Finned Tube
The processing technology of steel-aluminum composite finned tubes is to process bimetallic composite tubes on aluminum tubes and copper tubes first, and then undergo mechanical cold rolling, using the physical properties of aluminum tubes, centering on steel tubes, finned tubes as centers, cold rolling Aluminum pins are tightly coupled. When the steel-aluminum composite finned tube radiator is wet and cold in the heating and air-conditioning project, it is easy to remove the condensed water on the outer surface of the fins, and it is not easy to generate dust and dirt during heat exchange, such as dry heat.
