The difference between single metal finned tube and bimetal finned tubes
Single metal finned tube and bimetal finned tubes are finned tube type, the following distinction. Also known as finned tube heat pipe, into a single metal finned tube and bimetal finned tubes.
Single metal finned tubes made from rolled aluminum whole, said aluminum rolling finned tubes, non-contact thermal resistance, high strength, heat resistance and mechanical vibration, thermal expansion properties, and has a considerable extension of the heat transfer surface. With this fin heat exchanger tubing, sheets or effect ahead of the string around the chip type heat exchanger, is a very versatile heat exchanger. Single metal finned tubes can also be directly rolled steel or brass rolling from.
The copper fin tube is low finned tube, fin height and fin thickness less than 32mm, 0.3mm-4.0mm, fin spacing: 2.0mm-5mm
By the copper pipe as a whole, no contact thermal resistance, high strength, heat shock and mechanical vibration, thermal expansion performance is good, and has a considerable expansion of heat transfer surface, with the fin tube heat exchanger, the effect is ahead of the series or winding type heat exchanger. Widely used in petroleum, chemical, metallurgy, textile, mechanical and electrical, light industry, medicine and other industries in the process of heating, drying, condensation, cooling equipment.
Other single metal fin tubes: pure aluminum finned tubes, pure steel finned tubes
Bimetal finned tube into steel-aluminum and copper-aluminum composite finned tube finned tubes. Steel Aluminium composite fin tube is made (steel, aluminum; or stainless steel, aluminum) and then rolled out through composite fins, copper and aluminum composite finned tubes from (brass, aluminum) and then roll through the complex system of fins, has combined with tight, small resistance, good heat transfer performance, high strength, low flow loss, corrosion resistance strong, cold conditions in the long term is not easy deformation, long life and other advantages.
Bimetal finned tubes, the base pipe material do copper, carbon steel, stainless steel, outer pipe is made of aluminum.
Finned tube having a heat transfer area, high heat transfer efficiency, rugged, corrosion out strong, easy to clean, long life characteristics, is an internationally accepted, technologically advanced heat exchanger components.
Such finned tubes are widely used in petroleum, chemical, metallurgy, textile, machinery, light industry, medicine and other industries in the process of heating, drying, condensate, cooling equipment.
Brass diameter from Φ12 to Φ32mm; aluminum fins diameter from Φ18 to Φ64; films from 2 ~ 5mm, special specifications can be customized according to customer requirements.
Overall rolling fin no glitches, no wrinkles, easy to clean, wet When cooled in heating and air conditioning engineering in the outer surface of the fin easy to exclude condensate in the drying heating and other heat exchange situation is not easy knot dirt, fouling.
The factory production of single metal finned tube and bimetal composite finned tubes, surfaces are anodized, nice color, and can effectively prevent surface corrosion.
