Aluminum and steel Finned tube, copper fin tube

High-frequency welded helical finned tube is a highly efficient heat transfer component, it consists of steel fins wrapped helically around steel pipe, and continuously welded using the high frequency electric current welding process so as to reduce the flow resistance and the metal consumpition, improve the efficiency of heat transfer equipment and operating reliability. The heat transfer energy is more than 6-10times higher than the bare tubes.   Tube material: seamless steel, carbon steel Fin Material: Carbon steel; Stainless Steel     Extruded Finned Tubes are formed from a bimetallic tube consisting of a base tube and an aluminum muff tube. The fins are formed on a cold rolling process from the wall thickness of the aluminum muff tube. Extruded fin gives very good corrosion protection to the base tube, as the base tube is not visible to the atmosphere in between the fins. Tube material: carbon steel ; stainless steel; copper Fin Material: Aluminum L Foot Finned tubes The L fin design is for design temperatures less than 150degree,. This fin offers a certain degree of atmospheric protection of the tube wall against corrosion. The broad contact surface between the tube and the finning enhances heat transfer. This fin design is the most economical.   This fin is created by forming an aluminum strip into an L-shape which is then tension wound around the primary tube. Each L section is positioned against each other to ensure complete tube coverage. Also this manufacturing technology allows the use of relatively thin walled tubes.   Tube material: Any metal Finned material: Aluminum L Fin Design temp: <150 degree     Advantages of finned tubes 1. Passive heat exchange with no moving parts 2. Relatively space efficient 3. The cooling or heating equipment size can be reduced in some cases 4. The moisture removel capacity of existing cooling equipment can be improved 5. No cross-contaimination between air streams 6. Integral design minimizing the adverse effects of metal expansion 7. More efficient and therefore more cost effective than other similar solutions.   Field of Applications  Presently, finned tube has been widely used in chemicals, electric power, metallurgy, petrochemical complex, boiler, constrction, textile, environmental protection, dehydration, medical treatment and other industry heat transfer field and so on.   The applications for finned tubes are numerous. Listed below is just a sampling of typical application. Various economizers and heat recovery equipment, such as the recovery boiler flue gas, gas turbines, incinerators and other heat in the flue gas discharge. A. Glycol dehydration equipment B. Fired heater, such as LNG vaporizers, air pre-heaters, oil heaters, etc. C. Asphalt tank heaters D. Air coolers, such as compressor jacket water and lube oil coolers F. Lumber drying kilns, and similar applications G. Livestock enclosure and greenhouse heaters.   More Information, please contact Eva( 0086 0731 89925070 or 008618711054534 )
