Finned tube is mainly used for boiler economizer, air preheater, heat recovery, petrochemical
industry cracking furnace and etc.It can largely save energy and protect environment.Our company
can produce finned tube from Φ22mm to Φ250mm according to GB or customer's require.
According to the wing shape and structure, finned tube can be divided into the following categories:
Square finned tube,spiral finned tube,Longitudinal Finned Tube,Helical Serrated Finned Tubes,inner finned tube.
