Air Radiator Finned Tube Air Heat Exchanger

 

Function 
Because the air radiator is more suitable for steam - gas, liquid - gas heat exchange equipment, so, has been widely used in hot air heating, air conditioning, cooling, dehumidification, drying and other industrial and civil fields. Finned tube main material: copper series (copper tube fin), steel series (steel tube fin), steel aluminum composite series (aluminum steel tube fin), stainless steel series, copper aluminum sleeve sheet series. Finned tube main processing methods: the whole galvanized (tin) after mechanical winding, bimetallic (steel and aluminum, copper and aluminum composite) sleeve rolling, series galvanized, sleeve hydraulic expansion pipe. Industry application examples: Starch (air drying), food drying, milk powder (spray drying), tea drying, wood (drying kiln), papermaking (coater, paper machine), tobacco (silk, puffing), vegetable dehydration (tunnel, oven), textile (shaping, drying), beer malt (drying, cooling), workshop, room (heating), central air conditioning (hot, cold), power plant * cooling pipe, refining Oil factory exhaust pipe, ceramic exhaust pipe, steam turbine cooling pipe, chemical (dye, chemical fiber, soda, latex, PVC, gelatin, etc.)

The operating pressure of steam is 0.2 MPa to 1.6MPa; the temperatures of hot water and heat transfer oil are about 70ºC to 150ºC and 160ºC to 300ºC respectively.
 


Selection principles

Steel standards, thermal treatment states and permissible stress values of the materials of the pressure parts should be subject to requirements of the GB 150. The pressure parts used in inflammable, fatal or toxic operating environments should be made of cast iron.
The common parent tube materials include carbon steel Q235B, 20#, 304, 316, copper tube, etc.
The common fin materials include carbon steel, 304, 316, aluminum, etc.
