YUHONG GROUP Studded tube is mainly used in petrochemical and coal chemical industry for tubular heating furnace, convection heat exchanger, air preheater, chemical equipment, heat exchange equipment. To expand the heat transfer area of the light tube by 2 to 3 times, it can improve the heat transfer coefficient of the flue gas side, improve the comprehensive thermal efficiency of the equipment, and is an energy-saving heat transfer element. Its main function is to expand the heat transfer area of the tube and improve the thermal efficiency of the heating furnace.
YUHONG GROUP ASME SA213 T9 / ASTM A213 T9 material is the U.S. standard production of high temperature with chromium-molybdenum alloy heat-resistant steel, because of its good oxidation resistance, high temperature strength and resistance to sulfide corrosion performance, widely used in petroleum refining devices high temperature, high pressure, flammable, explosive pipeline, especially the heating furnace direct heat pipe, the medium temperature up to 550 ~ 600 ℃

Competitive Advantage:
Strong Bonding:
The high-frequency welding process ensures a strong metallurgical bond between the fin and the base tube, providing excellent thermal contact and mechanical strength.
Enhanced Heat Transfer Efficiency:
The welded fins significantly increase the surface area, improving the overall heat transfer efficiency of the tube.
Durability and Reliability:
The welding process creates a robust connection that is resistant to thermal cycling, mechanical stress, and vibrations, resulting in a durable and reliable heat exchanger component.
Corrosion Resistance:
The strong bond created by high-frequency welding helps to protect the base tube from direct exposure to corrosive fluids, enhancing the tube's corrosion resistance and extending its service life.
Uniform Fin Distribution:
The HFW process allows for precise and uniform fin spacing, which ensures consistent and efficient heat transfer across the entire tube length.
Versatility in Material Choices:
HFW fin tubes can be manufactured using a variety of materials for both the fins and the base tube, allowing for customization to suit specific application requirements, including different temperature and corrosion resistance needs.
Reduced Maintenance:
The robust construction and corrosion resistance of HFW fin tubes typically result in lower maintenance requirements, reducing operational costs and downtime.
Application Flexibility:
These fin tubes are suitable for a wide range of applications, including air-cooled heat exchangers, condensers, economizers, and boilers, due to their high efficiency and durability.
Compact Design:
The improved heat transfer efficiency of HFW fin tubes allows for more compact heat exchanger designs, saving space and potentially reducing material costs.
Efficient Production Process:
The high-frequency welding process is efficient and cost-effective, enabling the production of high-quality fin tubes at a competitive price.
