Comprehensive Guide to Mild Steel Pipes (MS Pipes)
Mild Steel Pipes (MS Pipes) are manufactured using premium low-carbon steel coils via the Electric Resistance Welded (ERW) or High-Frequency Induction (HFI) process. Renowned for their high tensile strength, supreme formability, ease of on-site welding, and cost efficiency, MS Pipes serve as the backbone of modern piping and industrial infrastructure.
At Mildsteelpipe.com, we stock and supply a comprehensive range of IS 1239 (Part 1) and IS 3589 certified Mild Steel Pipes in Light (Class A - Yellow Band), Medium (Class B - Blue Band), and Heavy (Class C - Red Band) wall thicknesses. All pipes undergo strict hydro-testing, eddy current weld inspection, and dimensional calibration.
Fire Fighting & Hydrant Systems
Medium and heavy class pipes designed to withstand sustained hydrostatic water pressure for industrial fire sprinkler networks.
Water Transmission & Plumbing
Municipal water distribution, borewell casing, irrigation pipelines, and HVAC chilled water recirculation loops.
Structural Framework & PEB
Circular columns, tubular roof trusses, space frames, pre-engineered buildings, and solar mounting structures.
Scaffolding & Heavy Engineering
Cuplock scaffolding pipes, heavy machinery rollers, conveyor idlers, and vehicle exhaust/chassis fabrication.
Mild Steel Pipe Weight Calculation Formula
The theoretical weight of any circular Mild Steel Pipe per meter is derived from its outside diameter (OD in mm) and nominal wall thickness (WT in mm) based on a steel density of 7.85 g/cm³:
Weight (kg/m) = (Outside Diameter mm − Wall Thickness mm) × Wall Thickness mm × 0.02466
For project estimation and bill of quantities (BOQ), fabricators and site engineers refer directly to our IS 1239 MS Pipe Weight Table above for standard factory rolling tolerances.
Frequently Asked Questions
Key technical and commercial answers regarding Mild Steel Pipes & ERW specifications.
IS 1239 (Part 1) covers Mild Steel ERW tubes for nominal bore sizes up to 150mm NB (6 inches) categorized into Light, Medium, and Heavy classes. IS 3589 covers larger diameter steel pipes from 168.3mm OD (200mm NB / 8 inches) up to 2540mm OD, typically utilized in major civil water mains, industrial gas lines, and sewage conduits.
As per Bureau of Indian Standards (BIS) IS 1239 norms: Light Class (Class A) is identified with a Yellow Band; Medium Class (Class B) with a Blue Band; and Heavy Class (Class C) with a Red Band at both pipe ends.
Standard rolling lengths are 6.0 meters to 6.4 meters in plain squared ends or bevelled ends for butt welding. Custom lengths can also be supplied for bulk commercial orders upon request.
Yes, all prime material dispatches are accompanied by manufacturer Mill Test Certificates (MTC) detailing hydro-test pressure (minimum 50 bar), chemical analysis (Carbon, Manganese, Sulphur, Phosphorus), and tensile test parameters.
