Cold wound spiral galvanized finned tubes are heat transfer tubes designed to increase external surface area by helically winding metal fins onto a base tube, then applying galvanization for corrosion protection.
They are widely used in heat exchangers, air coolers and industrial thermal systems where high heat transfer efficiency and long service life are required.
The cold wound spiral fin design provides tight and uniform fin attachment to the base tube. This structure ensures stable mechanical bonding and reliable performance during long-term operation under industrial working conditions.
The galvanized coating effectively protects the finned tube from corrosion caused by moisture, chemicals and outdoor exposure. This makes the tube suitable for harsh environments and significantly extends its service life.
By increasing the external surface area through spiral fins, the finned tube improves heat exchange efficiency compared with plain tubes. This design helps optimize thermal performance in heat exchangers and air cooling systems.
Cold wound spiral galvanized finned tubes are widely used in outdoor installations and industrial systems, such as air coolers, heat exchangers and processing equipment, where durability and heat transfer efficiency are required.
With robust construction and corrosion-resistant surface treatment, the finned tubes offer long service life and reduced maintenance frequency, helping lower operating costs for industrial users.
