Lord Fin Tube--What is extruded fin tubing?

What is extruded fin tubing?

Aluminum extruded fin tubings, also known as "integral finned tubes," are formed by machine extrusion of a base tube covered with aluminum tube (the base tube can be carbon steel, stainless steel, or copper) to form a tube fin, the fin base and the tube outer wall are close fitting, and this fin tubing control can produce finned tubes with high heat transfer coefficient and heat transfer performance. Extruded fin tubing can be made of iron, copper, or aluminum tube through compound rolling, which has the advantages of tight bonding, low thermal resistance, good heat transfer performance, high strength, low flow loss, strong anti-corrosion performance, not easily deformed under long-term hot and cold working conditions, and long working life.

Extruded fin tubing manufacturing process

Pipe line——compressing or rolling——strip peeling——washing——pressure test——blast blowing——packaging.

Extruded fin tubing is made up of a bimetallic tube made up of an aluminum outer tube and an inner tube made of almost any material. The fin is formed by rolling the material from the outside of the outer tube, resulting in an integrated fin with excellent heat transfer performance and longevity. The base tube is well protected against corrosion thanks to the extruded fins.

The extrusion method is used to manufacture the composite finned tube: the bimetallic composite tube is lined with a mandrel, and the composite tube is processed on the outer surface through the cavity formed by the rolling groove and the core head Out fins. This method produces a heat transfer tube that is an organic whole with its outer tube and fins, so there is no contact heat loss, and it has good performance and high heat transfer efficiency.

The benefit of extruded fin tubing

When compared to the ordinary wound finned tube, the contact thermal resistance remains stable over a wide temperature range, implying that the heat transfer performance of the bimetallic aluminum extruded finned tube is superior to the spiral fin tube in the limit tube wall temperature range.

Furthermore, when compared to the coiled tube, the bimetallic aluminum extruded fin tube has superior corrosion resistance and high strength; it can withstand 4.0MPa water pressure cleaning without the fins falling down, and the base of the bimetallic aluminum extruded tube. The tube can be chosen based on the corrosion of the fluid in the tube as well as the processing technology. The base tube can be made of carbon steel, copper, stainless steel, or another material.

Applications of extruded fin tubing

Extruded fin tubings are the primary components of air coolers and are frequently used as heat exchangers in power plants (electric, nuclear, thermal and geothermal). System for collecting steam condensate. Industries such as petrochemicals and chemicals. Refrigeration and food processing plants. Industry (steel mills, incinerators, gas compression facilities) (steel mills, incinerators, gas compression facilities). Petrochemical, power plant and power plant renovation, air conditioning and refrigeration, boilers, finned tube economizers, and air preheaters are just a few of the industries we work in. The maximum working temperature ranges between 280°C and 300°C.
