Extruded Finned Tubes
Extruded finned tubes are bimetallic tubes whose outer aluminium surface is finned by cold plastic deformation.
The general materials of base tubes about the extruded finned tube are carbon steel, copper, alloy, stainless steel ; the general materials of fins about the extruded finned tube are copper, aluminum 1060/1070, aluminum alloy 6063/6061.Therefore, it is generally divided into four categories: steel aluminum composite finned tubes; copper aluminum composite finned tubes; pure aluminum composite finned tubes, pure copper composite finned tube.
Extruded finned tubes application:
1.Operating temperatures less than 300°C;
2.Offshore or other remote applications;
3.Dry air coolers for air, gas or oil;
4. Air to air heat exchangers for HVAC applications;
5. Air dehumidification in air treatment plants;
6. Eenergy recovery in air exhaust system, etc
This page let's talk about ASME SA249 stainless steel extruded finned tubes with AL1060 fins.
Detailes of ASME SA249 Welded Base Tubes ( Generally with min. wall thickness )
SA249 This specification covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes, with various grades intended for such use as boiler, superheater, heat exchanger, or condenser tubes.
