Boiler Auxiliaries Solid Spiral Serrated Fin Tube for Heat Exchanger
H-type finned tube heat exchanger elements maintain high heat transfer capacity, possess superior self-cleaning properties, and effectively recover flue gas waste heat in boiler renovations. Convective heat transfer coefficient is proportional to fin pitch but inversely proportional to fin height and width.
Product Details
H-type finned tubes improve heat exchange efficiency through extended surface heat transfer and have been widely used in boilers and waste heat recovery systems. Derived from rectangle finned tubes, their unique groove structure provides excellent anti-wear and anti-fouling performance.
Customizable Structure
Our H-fin tubes are designed and manufactured to be safe, reliable, and efficient, with modifications available according to customer requirements. HD BOILER maintains comprehensive quality assurance systems, producing H-fin tubes with high heat transfer efficiency, optimized flue gas resistance, and compact space requirements.
