high frequency welded finned tube for air pre-heater

Place of Origin:	Hebei

High-frequency welded helical finned tube is a highly efficient heat transfer component, it consists of steel fins wrapped helically 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 the bare tubes
