l 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.

designed to combine the structural strength of stainless steel with the thermal advantages of aluminum or copper. The base tube of the stainless steel finned tube is manufactured from high-quality stainless steel, while the fin material can be stainless steel, aluminum, or copper depending on heat transfer and corrosion requirements.

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.

combine the structural strength and cost efficiency of carbon steel with flexible fin material options including stainless steel, aluminum, and copper. The base tube of the carbon steel laser welded finned tube provides excellent pressure resistance and mechanical stability, while the selected fin material determines thermal conductivity and corrosion 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.

Stainless steel base tube provides superior corrosion resistance and mechanical strength. Aluminum fins are cold-extruded to form a strong mechanical bond. No air gap between fin and tube ensures stable heat transfer performance. Suitable for humid and mildly corrosive environments. Long service life with low maintenance cost.
