High-frequency welded helical finned tube is a highly efficient heat transfer, it consists of steel fins

wrapped heliclly around steel pipe, and continuously welded using the high frequency electric current

welding process so as to reduce the flow resistance and the metal consumption, improve the efficiency

of heat transfer equipment and operating reliability.

The heat transfer energy is more than 6-10 times higher than bare tubes.
