Product introduction
Single metal Finned Tube and double metal composite finned tube
The single metal finned tube is integrally rolled from aluminum tube, with no contact thermal resistance, high strength, heat resistance and mechanical vibration, good thermal expansion performance and considerable expansion heat exchange surface. The Heat Exchanger made of this Fin Tube is a kind of heat exchanger with a wide range of applications. Bimetallic composite Finned Tubes are copper and aluminum tubes (or steel tubes, aluminum tubes; or Stainless steel tubes, aluminum tubes) which are rolled out after being combined. They have the advantages of tight combination, small thermal resistance, good heat transfer performance, high strength, small flow loss, Strong Corrosion Resistance, not easy to deform under long-term cold and hot conditions, and long service life. The integrally rolled fins are free of burr and wrinkle, Easy To Clean, easy to remove the condensation water on the outer surface of fins during wet cooling in heating and air conditioning engineering, and not easy to form dust and scale in drying and heating and other heat exchange occasions. The aluminum rolled finned tubes and bimetal composite finned tubes produced by our factory. The surface is anodized, the color is beautiful and generous, and can effectively prevent surface corrosion.
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 integrally rolled from aluminum tubes, with no contact thermal resistance, high strength, heat shock resistance and mechanical vibration resistance, good thermal expansion performance, and considerable expansion heat exchange surface. The heat exchanger made of this kind of finned tube has a better effect than the tandem or wound fin heat exchanger. Copper aluminum composite finned tube is a kind of finned tube that is rolled out after copper and aluminum tubes are combined. It has the characteristics of tight combination, small thermal resistance, good heat transfer performance, high strength, small flow loss, strong corrosion resistance, not easy to deform under long-term cold and hot conditions, and long service life. The integrally rolled fins are smooth and free of burr and wrinkle, and easy to clean. During wet cooling in heating and air conditioning engineering, it is easy to remove the condensation water on the outer surface of the fins, and it is not easy to form dust and scale in drying, heating and other heat exchange occasions. The surface of aluminum rolled finned tubes and copper aluminum composite finned tubes produced by our factory are all anodized, with beautiful color and generous appearance, which can effectively prevent surface corrosion. The factory can also process steel Wound Finned Tubes and steel aluminum composite finned tubes according to the needs of users.

1. Loose fin tube
The wound finned tubes are all made of (steel, aluminum, copper, stainless steel, etc.) tape wound (steel, aluminum, copper, stainless steel, etc.) tubes
It is mechanically wound in a spiral shape and has three different sheet pitches: 3.2mm "R", 4.2mm "m" and 6.5mm "t".
R pitch, small pitch and large heat dissipation area, with large heat dissipation;
M sheet distance, the sheet distance is large, and the heat dissipation and air resistance are small;
T-piece distance, suitable for the situation of high steam pressure and low air temperature rise.
