What Are MS Round Pipes?

MS Round Pipes, also known as Mild Steel Round Pipes, are circular hollow steel sections manufactured from low-carbon steel. These pipes are widely used across construction, industrial, agricultural, fabrication, and infrastructure sectors due to their excellent strength, durability, and affordability.

Mild steel typically contains a low percentage of carbon, making it easier to weld, machine, bend, and fabricate. MS round pipes are available in various diameters, wall thicknesses, and lengths to suit different applications.

Common types include:

• ERW round pipes
• Black steel pipes
• Structural steel pipes
• Hollow circular sections
• Industrial steel tubes

These pipes are used for fluid transportation, structural support, fabrication work, scaffolding, fencing, machinery manufacturing, and industrial installations.

How MS Round Pipes Are Manufactured

The manufacturing process of MS round pipes involves multiple quality-controlled stages to ensure dimensional accuracy and structural integrity.

• HR Coil Procurement: High-quality Hot Rolled (HR) steel coils sourced from reputed steel manufacturers.
• Slitting Process: Large steel coils are slit into narrower strips according to the required pipe diameter.
• Roll Forming: The steel strips are gradually shaped into a cylindrical form using precision rollers.
• Welding: The edges are joined using Electric Resistance Welding (ERW) technology to create a continuous pipe.
• Sizing and Straightening: Pipes pass through sizing mills to achieve accurate dimensions and perfect roundness.
• Testing and Inspection: Hydrostatic testing, dimensional inspection, weld integrity checks, and visual quality checks before dispatch.

Key benefits include cost-effective piping, excellent dimensional accuracy, suitability for fabrication, and consistent quality. Widely used in industrial fabrication, construction, and infrastructure sectors. We also supply industrial-grade ERW Pipes supplier in India solutions for heavy engineering.

Black MS Round Pipes

Black MS pipes are uncoated steel pipes with a black oxide surface finish, extensively used for water transportation, structural applications, fencing, and fabrication projects.

Heavy Class MS Pipes

Heavy class MS pipes feature thicker walls and enhanced load-bearing capacity, suitable for industrial plants, structural engineering, and high-stress applications.

Structural Round Hollow Sections

Structural hollow sections provide excellent strength-to-weight ratio, commonly used in building frameworks, industrial sheds, warehouses, and infrastructure projects.

Industrial Steel Tubes

Precision-engineered pipes designed for machinery manufacturing, mechanical engineering, process plants, and industrial equipment.

100 NB	114.3	3.6 – 6.3	Infrastructure projects
150 NB	168.3	4.0 – 8.0	Heavy industrial applications

MS Round Pipe Weight Chart

Pipe weight plays a critical role in procurement, transportation, fabrication, and structural design calculations.

Weight Formula: Pipe Weight (kg/m) = (OD - Thickness) × Thickness × 0.02466 (where OD = Outside Diameter mm, Thickness = Wall Thickness mm)

OD (mm)	Thickness (mm)	Weight (kg/m)
33.7	2.6	2.00
42.4	2.6	2.57
48.3	3.2	3.56
60.3	3.6	5.04
76.1	3.6	6.47
88.9	4.0	8.37
114.3	4.5	12.16

Accurate weight calculations help estimate transport loads, fabrication costs, structural calculations, and material procurement budgets.
