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
