Our H-type finned tube heat exchanger elements are engineered to deliver exceptional heat transfer capabilities. They boast superior self-cleaning properties and excel in flue gas waste heat recovery, especially during boiler renovations. The convective heat transfer coefficient is directly proportional to fin pitch, while inversely related to fin height and width. Overall heat transfer capacity is influenced by fin efficiency, convective heat transfer, and finned ratio. Note: Pressure drops increase with greater fin height and width.
To enhance heat exchange efficiency and optimize surface heat transfer, H-type finned tubes have become a staple in modern boilers and waste heat recovery systems. Derived mainly from rectangular finned tubes, these tubes feature a unique grooved structure that provides outstanding anti-wear and anti-fouling performance.
We customize our products to meet the specific needs of our customers, ensuring the design and manufacture of safe, reliable, and efficient H-fin tubes. At HD Boiler, we uphold rigorous stand-alone product quality assurance systems. Our H-fin tubes are known for their high heat transfer efficiency, flue gas resistance, and space-saving design.
· For special cargos, such as overlength, overwidth, overheight, and overweight items, we utilize frame boxes for easier handling and transportation.
· For standard goods, we prefer using ordinary containers.
· After loading, we ensure that all goods are securely reinforced.
With 38 years of industry expertise in research, development, and manufacturing, we possess substantial production capacity.
