Finned Steel Tube
Fin tube is an efficient heat transfer element with spiral fins. Its heat transfer area is several to dozens of times that of a light tube, which can enhance heat transfer, reduce flow resistance, and reduce metal consumption, thus improving the economy and operational reliability of heat exchange equipment. Fin tubes have been widely used in various boilers.
Gnee Steel (Tianjin) Co., Ltd. is one of the most reliable manufacturers and suppliers of finned steel tube in China, also supports customized service with low price. Welcome to wholesale discount finned steel tube for sale here from our factory. Contact us for free sample.
Fin tubes are made of metal tubes and steel strips welded by equipment. Fin tubes are mainly used in large heat exchangers because they can increase the heat exchange area, which can save more energy.

Advantages of finned tube
Provide 8 to 12 times the heat transfer area of bare tubes.
More efficient than bare tubes.
Provide smaller exchangers due to increased Heat Transfer area.
Often provide a more economical selection.
Fins can be "Cut & Twist" to increase shell side fluid turbulence and improve heat transfer.
