Ferrous pipe is the first branch of metallic pipe and is basically iron based material. Cast Iron is an alloy between iron and carbon with a carbon weight content of more than 2 weight percent of Carbon. Some says between 2 and 6.67 percent carbon.
This material is often combined with other elements in an effort to increase corrosion resistance, such as by adding elements of Silicon, Nickel or Chromium. Other elements that are also sometimes given are manganese, phosphorus and sulphur.
Cast Iron is strong in compression, but low in ductility and malleability, and very brittle, Thus this type is not suitable for pressure piping applications. The properties of Cast Iron depend on how much carbon content and the shape of the carbon itself is graphite or carbide.
| Where we can use Cast Iron Pipe? |
| Cast Iron type pipes are widely used for drain, waste, and vent (DWV) applications, which is also known as “soil pipe.” |
