Stainless Steel Tube for Heat Exchanger

Air heat exchanger is a kind of heat exchanger that is used to cool or heat forcibly flowing air with water, glycol solution, steam or heat conduction oil as the medium. It is extensively applied in hot air heating, drying, cooling, dehumidifying and other works in such industries as light industry, building, chemical engineering, machinery, textile, printing & dyeing, electronics, food, starch, medication, metallurgy and painting. Different models of heat exchanger should be selected according to the actual working conditions.

Heat exchange tube and fin
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.
