NICKEL ALLOY FINNED TUBE ASME SB163 UNS N04400 25*2*9000MM G TYPE FIN GRADE AL99.5 FOR HEAT EXCHANGER COOLER
ASTM B163 UNS N08825 Nickel Alloy 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 is similar to Alloy 800 but has improved water corrosion resistance. 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.

Extruded finned tubes are bimetallic tubes whose outer aluminium surface is finned by cold plastic deformation.
1. They can work at a maximum temperature of 285 degrees Celsius
2. They have an excellent level of atmospheric corrosion resistance
3. They are purely made up of aluminium
4. Offers excellent mechanical resistance
Why Choose Extruded Finned Tube?
Most of the industries choose extruded fin tubes as they offer a better level of resistance against corrosion. This helps them
to be highly durable thus letting you have a strong heat exchanger. Along with this， they can withstand mechanical stress，
thus provide flawless results. It is generally used with industries that do not require the material to reach a very high temperature.
