Spiral Wound Finned Tube

Economical finned tube solution for general applications.
Aluminum or copper fin strip helically wound around the base tube.
Continuous L-shaped foot provides full coverage of the tube surface.
Good heat transfer performance with low production cost.
Suitable for moderate temperature operating conditions.

Enhanced corrosion protection compared with L Type.
Double L-shaped foot design provides better tube surface coverage.
Improved fin stability and stronger mechanical bond.
Suitable for humid and mildly corrosive environments.
Reliable long-term performance.

Base tube surface is knurled before fin winding.
Stronger mechanical bonding between fin and tube.
Improved heat transfer efficiency due to better contact.
Higher resistance to fin loosening during operation.
Suitable for higher temperature and vibration conditions.

Fin strip embedded into a machined groove in the base tube.
Excellent fin-to-tube bonding and heat transfer performance.
High resistance to mechanical stress and vibration.
Suitable for higher operating temperatures.
Long service life in demanding environments.
