High Frequency Welding Boiler Fin Tube for Central Heating HD Boiler with Corrosion Resistant Finish
Central heating radiator with high-frequency welded fin tubes for efficient heat transfer in boiler systems.
H-type finned tube heat exchanger elements maintain a high capacity for heat transfer, possess superior self-cleaning properties and retain the ability to effect flue gas waste heat recovery in boiler renovations. Convective heat transfer coefficient is proportional to fin pitch, but inversely proportional to fin height and fin width.
H-type finned tubes have been widely used in boilers and waste heat recovery due to their unique groove structure on the fin surface, which provides excellent anti-wear and anti-fouling performance. Our products can be customized according to specific requirements.
