Mild Steel Pipe Industrial Applications
MS pipe serves construction, plumbing, oil and gas, and HVAC.
Construction & Structural Applications
Mild steel pipes are used in buildings as vertical columns, temporary scaffolding frameworks, and structural supports to safely bear applied loads.
Plumbing & Water Supply
For water distribution and plumbing networks, engineers commonly choose galvanised mild steel pipes because their protective coating resists corrosion.
Oil & Gas Pipelines
Pipelines made from API 5L specification steel pipe are widely used to convey crude oil and natural gas over long distances.
Firefighting & HVAC Systems
In fire sprinkler installations and HVAC piping networks, engineers typically specify Schedule 40 black mild steel pipes as the common standard.
Mild Steel Pipe vs GI Pipe
MS and GI pipe share the same base metal but differ in surface treatment.
| Property | MS Pipe (Black) | GI Pipe (Galvanised) |
|---|---|---|
| Corrosion Resistance | Low | High |
| Cost | Lower | 15 to 30% higher |
| Applications | Gas, structural, industrial | Water supply, outdoor |
