Finned Tubes
A finned tube is a heat transfer device consisting of many parallel metal fins commonly used for heat dissipation and cooling applications. Finned tubes increase the surface area of the pipe, thus increasing the heat transfer efficiency. Finned tubes are commonly used in applications such as air coolers, automotive radiators, condensers, and evaporators. They are also used in industrial heaters and refrigerators to increase heat transfer surface area and improve efficiency.
Finned tube is a kind of new, wear-resistant, efficient heat exchange material, is a kind of energy-saving heat exchange element, it uses high-frequency power source as heat source, the steel strip, steel pipe heating at the same time, so that the fusion welding together into one, with high heat exchange efficiency, large cooling area, long service life, adapt to a wide range of temperature, high pressure characteristics, it can also be made of a variety of materials, Excellent heat transfer, durability, heat resistance and corrosion resistance. Widely used in waste heat recovery, petrochemical, power plant boiler, economizer, bus, industrial and civil construction heating, refrigeration, medical drying, wood drying, food drying system and other industries.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them.
