During the first half of the 20th century, cast iron was used in many utility systems. Steel replaced cast iron as the material of choice in the 1950s, but that means that there are a lot of older cast iron pipelines still in service.Deadly Dangers Lurk In Natural Gas Distribution Lines(PDF) Comparison and Analysis of Pipeline Failure Statistics
