ASTM B163 Embedded G Type Al Fin Tube NO8825 Tubo Aletado

ASTM B163 Embedded G Type Al Fin Tube NO8825 Tubo Aletado


YUHONG Group can handle kinds of projects, such as heat exchanger / boiler projects, marine projects, oil & gas projects etc. We offers ASME SB163 Embedded G-Type Aluminum Fin Tube NO8825 and we sell this fin tubes in over 70 countries.


Embedded Fin Tubes also called G type Finned Tube, Embedded Finned Tube provides a perfect connection between the fin and the tubes . The Embedded Fin tubes main design is that through professional equipment groove the tubes and fin insert fins into the helical groove. Finally combined the fin and tubes as intergral.(G-Fins) are made by winding aluminium or copper strip into a helical groove machined on the outer surface of the tube. Embedded Fin tubes can be used in higher temperatures and are very durable. Embedded Fin tubes are best suited for the usages that involve high thermal cycling or high temperatures and where the fin side will be subjected to regular cleaning .

Detailes Of Incoloy 825 / NO8825 Tube


ASME SB 163 N08825 Nickel Alloy TUBE is a nickel-iron-chromium alloy with added molybdenum and copper. The chemical composition of this nickel steel alloy is designed to provide superior resistance to many corrosive environments. It has excellent resistance to reducing and oxidizing acids, stress corrosion cracking, and localized corrosion such as pitting and crevice corrosion. Alloy 825 Incoloy 825 is particularly resistant to sulfuric and phosphoric acid. This nickel steel alloy is used in chemical processing, pollution control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production and pickling equipment.
