MS Pipe Weight Calculator (Round, Square & Rectangular)
Calculate theoretical weight for Mild Steel (MS), Galvanized Iron (GI), and structural steel pipes. Instant weight in kg and Metric Tonnes (MT) for Circular (CHS), Square (SHS), and Rectangular (RHS) hollow sections with live steel rates per kg and 18% GST.
Dimensions & Section Parameters
Enter outer dimensions, wall thickness, commercial length, and piece quantity.
Engineering Specification Sheet
IS 1239 / 4923Steel Pipe Weight Formulas & IS 1239 / IS 4923 Indian Standards
Mild steel has a standardized density of 7,850 kg/m³ (0.00785 g/mm³). Based on this physical constant, the Bureau of Indian Standards (BIS) formulates simplified empirical multipliers for rapid on-site weight estimation.
Round Pipe Formula
Where OD is outer diameter in mm, T is wall thickness in mm, and 0.02466 is \(\pi \times 0.00785\).
Square Pipe (SHS) Formula
Applies to all square hollow box sections per IS 4923 (APL Apollo, Tata Structura, Jindal).
Rectangular (RHS) Formula
Evaluates total perimeter volume multiplied by steel density 7.85 kg/dm³.
Frequently Asked Questions (FAQs)
What is the standard length of an MS pipe in India?
In India, commercial MS pipes, GI pipes, and square/rectangular box tubes are manufactured in standard lengths of 6.0 meters (approximately 19.68 to 20 feet). Custom cut lengths from 4m to 12m can be ordered from mills.
What are Light (A), Medium (B), and Heavy (C) class pipes in IS 1239?
Under IS 1239, pipes with identical outer diameters have different wall thicknesses and color codes: Light Class (A-Class) has a Yellow band, Medium Class (B-Class) has a Blue band, and Heavy Class (C-Class) has a Red band for high-pressure steam and fire hydrant lines.
What is the difference between MS pipe and GI pipe weight?
GI (Galvanized Iron) pipe is an MS pipe coated with hot-dip zinc. Zinc coating adds approximately 3% to 5% additional weight depending on coating thickness (minimum 360 to 400 g/m² per IS 4736).
