Mild Steel Electric Resistance Welded Pipes (MS ERW Pipes) have a carbon content of less than 0.18%. They are not considered hardened pipes since they have low carbon content. They are also called ‘Black Pipes’ since they are not galvanized. Mild steel is available in a variety of structural shapes that are easily welded into pipe, tube, tubing etc. Mild steel pipes and tubes are easy to fabricate, readily available, and cost less than most other metals. In well protected environments, the life expectancy of mild steel pipe is 50 to 100 years. |
