Non-Ferrous Metal Aluminum, Copper, Nickel, Titanium – Piping Training Video-5

Non-Ferrous Metal Aluminum, Copper, Nickel, Titanium – Piping Training Video-5


Non-ferrous material are small part of total
piping material, and they used in very aggressive corrosion environment. • Non-ferrous material Contains no iron
or in very insignificant amount • Metal such as Aluminum, Copper, Nickel,
Titanium etc. are the example of Non-ferrous material
• Material used in Process Ind. − Copper and Copper Alloys
− Nickel and Nickel Alloys − Aluminum and Aluminum Alloys
− Titanium and Titanium Alloys − And Zirconium and Zirconium Alloys, Non-ferrous
material is also known as exotic material. Copper and Copper Alloys has a
• Good thermal conductivity • Good corrosion resistance
• Brasses, Bronzes (Cu-Sn) and Cupronickels (Cu-Ni) are some of the example of copper
alloy • Cupronickels have highest corrosion resistance
among Cu alloys • Cupronickels are used for heat exchanger
tubing and sea water application • It Can be used as cladding material with
carbon steel Nickel and Nickel Alloys has a
• Good resistance to oxidation and corrosion • Monel 400 and Hastelloy are well known
example • Nickel and Nickel Alloys are Used in piping
systems, pressure vessel, turbine blading, valves, and power plant accessories that handle
steam • Nickel Alloys are Frequently used as a
cladding material with carbon steel Aluminum and Aluminum Alloys has a
• Good thermal conductivity • Most workable metal
• Highly resistant to atmospheric conditions • But When coupled with more noble materials
it is subject to galvanic attack • And Loses strength rapidly above 175°C
• Rarely used in process piping • However, it is used as an external clad
material for insulation to protect insulation. Titanium and Titanium Alloys has a very
• High strength to weight ratio • Similar to SS Titanium Oxide is formed
which prevents corrosion • Titanium and Titanium Alloys has a Resistant
to Nitric acid which is very corrosive in nature. Hence, it is used in this kind of process
environments • But to Weld Titanium and Titanium Alloys
inert atmosphere is required. And
• Loses strength above 400°C • It Can be used as clade material with
carbon steel Zirconium and Zirconium Alloys
• are used, where strong acids and alkalis are present, where other material cannot be
used due to very aggressive environment Let’s summarize What you have learned in
this lecture • definition of Non-ferrous Metal
• Types of Non-ferrous metal used in Process Piping
• And Properties of these Non-ferrous materials See you in the next lecture.
