Introduction: What is Cast Iron?
Cast iron pipe, which were mainly composed from grey cast iron, were crude pipes made from molds. The grey colour from grey cast iron came as a result of graphitic microstructures (as a consequence of graphite being present in the mixture). Cast iron pipes were commonly used up until the turn of the 20th century [1].

Cast Iron Pipes
Cast iron is rated in eight classes, from A to H, based on pressure. Each of the incriments between the classes is 100 feet of head or ~43 psi. To check out the full specification for the pipe size and classes, navigate to the link below [3].

Some advantages to Cast Iron includes its thicker wall size than other pipes such as steel and ductile iron.
Some disadvantages to Cast Iron include its suseptability to rust/corrosion, clogging, cracking, holes, and collapsing. The longer cast iron is immplimented, the more waste that builds up because of its uneven interior. Furthmore, Cast Iron Pipes have no elasticity, low mechanical strength, and often no external protection.

Example Applications
For cast iron pipes specifically, they were mainly used as pressure pipes to transport water and sewage waste. The design of Cast Iron cast iron hasn't changed much since its high demand in the the 19th and 20th century and its no longer in demand as different solutions have come into place [1].
