Extruded fin tube, Base tube ASME SA179, Fin Material ASME SB221 Al 1060, Air Cooler application
Yuhong Holding Group has more than 35 years experience for steel pipe and tube , fin tube , main application for Petrochemical , Oil refinary, Furnace, heating, boiler, heat exchanger, air cooler,.., till now YUHONG brand products already exported more than 85 countries, which like UK, ITALY, SPAIN , USA, MEXICO , COLOMBIA , BRAZIL, SAUDI ARANBIA , OMAN, QATAR, U.A.E, KOREA, ...., YUHONG brand already won good reputation in the market .
Yuhong Group supply variety of extruded fin tubes in the industry. All of our products are domestically sourced, developed, and produced, which means our customers have immediate access to exactly the products they need for their particular application. And you are assured of the highest quality and manufacturing standards and a local, concerned, customer service presence.The strong connection between fin and base tube prevents loosening of fin because of heat stress, oxidization, corrosion etc., use at very high temperatures possible. This extruded finned tubes configuration can be used in practically any heat transfer applications, and particularly suited for high temperature, high pressure applications. The important features of this configuration are efficient, effective bond of fin to tube under any conditions of temperature and pressure, and ability to withstand high fin-side temperatures.
Tube/Pipe Size of OD: 15.88mm to 76.2mm
Fin tube length: 34m/c Max.
Fin Height :10 mm to 50.8mm
Fin Thickness: 0.2mm ~ 0.5 mm
Fin Pitch :1 to 20 fins per inch
Materials of base tube: Carbon Steel ,Alloy Steel ,Stainless Steel and Corrosion-resistance Steel.
This fin type is formed from a bi-metallic tube consisting of an aluminium outer tube and an inner tube of almost any material. The fin is formed by rolling material from the outside of the exterior tube to give an integral fin with excellent heat transfer properties and longevity. Extruded fin offers excellent corrosion protection of the base tube.
