Reading the table: "WT" = wall thickness in millimetres. "kg/m" = weight per metre in kilograms. Standard supply length is 6 metres, so multiply any kg/m value by 6 to get the weight of one full pipe length.

Class A (Light) MS Pipe Weight Chart

Class A is the lightest wall thickness in IS 1239 and is also called Light class or A-class. It is specified where weight reduction matters more than pressure rating. Per-metre cost is the lowest of the three classes.

MS Pipe Schedule 40 & Schedule 80 Weight Chart

Most international project drawings, oil and gas documentation, and export purchase orders follow ASME B36.10M, the American standard. See the MS pipe schedule 40 and MS pipe sch 80 weight charts for common export sizes from ½ inch to 16 inch.

How Schedule maps to IS Class

Schedule 40 is broadly equivalent to IS 1239 Class B (Medium) – but not identical. Always specify the standard on every PO.
Schedule 80 is heavier than IS 1239 Class C (Heavy).
For thicker walls than Sch 80, the schedule ladder continues: Sch 120, Sch 160, and XXS (Double Extra Strong).

600	24"	609.6	6.3–14.2	93.78–208.64

Engineering note: Barlow's method and a 12.5% corrosion allowance are used to calculate wall thickness for pressurised lines exceeding 200 NB. Sachiya Steel offers IS 3589 pipes in Fe 330, Fe 410, and Fe 450 grades. Please specify the grade, thickness, and finish.

ERW MS Pipe Weight Chart

ERW is the dominant manufacturing route for mild steel pipe in India. A flat strip is rolled into a cylinder and fused by high-frequency current without filler metal. These pipes are consistent and weigh the same per metre as seamless mild steel pipes for the same NB and class.

Practically, the ERW MS pipe weight chart and the seamless MS pipe weight chart are identical under IS 1239 standards. While the manufacturing process affects pressure ratings and temperature suitability, the theoretical weight remains the same. Always refer to the master IS 1239 dimensions for specific mild steel pipe weights.

MS Hollow Pipe Weight Chart – Round, Square, Rectangular

MS hollow sections are marketed by outer dimension, not nominal bore, and are governed by IS 4923 for square and rectangular profiles and IS 1239 for round profiles. Steel frames, gates, awnings, racking, and light structural work use them by default. MS round, square, and rectangular pipe weight charts are in the three sub-tables below.

GI Pipe Weight Chart – MS Pipe with Zinc Coating

GI pipe is a zinc-coated mild steel pipe following IS 1239 standards. While size charts match, the galvanisation adds 1–3% to the total weight. The table below lists standard weights for these pipes.

NB (mm)	Size (in)	OD (mm)	Class B GI kg/m	Class C GI kg/m
15	½"	21.3	1.234	1.510
20	¾"	26.9	1.591	1.907
25	1"	33.7	2.458	2.989
32	1¼"	42.4	3.162	3.866
40	1½"	48.3	3.631	4.457
50	2"	60.3	5.131	6.314
65	2½"	76.1	6.548	8.089
80	3"	88.9	8.527	10.098
100	4"	114.3	12.342	14.688
125	5"	139.7	16.218	18.156
150	6"	165.1	19.380	21.624

Practical note: For most procurement estimates, GI and MS weights are treated as equal. The 1–3 % zinc uplift becomes significant only for very large quantities or precise freight calculations.

MS Pipe Weight Formula & Density

If you need a size that is not on the chart – for example, an odd-thickness pipe, a non-standard diameter, or a custom requirement – you can calculate the weight per metre using the standard MS pipe formula used across the Indian steel industry.

MS PIPE WEIGHT FORMULA

Weight (kg/m) = (OD − t) × t × 0.02466

OD = outer diameter (mm), t = wall thickness (mm), 0.02466 = π × density of steel (7.85 g/cm³) ÷ 1000

Worked example – 50 NB (2 inch) Class B

Outer diameter = 60.3 mm, wall thickness = 3.6 mm. Plugging into the formula:

Weight = (60.3 − 3.6) × 3.6 × 0.02466 = 56.7 × 3.6 × 0.02466 ≈ 5.03 kg/m

This matches the IS 1239 chart value for 50 NB Class B exactly. The same MS pipe unit weight formula works for any size – round, ERW, or seamless – provided you know the outer diameter and wall thickness.

Density of MS Pipe & Physical Properties

The density of MS pipe is 7.85 g/cm³ (7,850 kg/m³). Every theoretical weight in this MS pipe weight chart uses this BIS and ISO mild steel reference value. The summary below covers structural engineers' and procurement teams' most requested physical attributes.

Property	Value

MS pipe weight charts show mild steel pipe per-metre weights for each nominal bore and wall-thickness class. The chart in India uses IS 1239 Part 1 for 15 mm to 150 mm NB and IS 3589 for greater sizes. Material estimation, freight calculation, and structural load checking are done by buyers.

How do you calculate MS pipe weight per meter?+

Use the formula Weight (kg/m) = (OD − t) × t × 0.02466, where OD is the outer diameter and t is wall thickness in mm. To find 0.02466, multiply π by mild steel density (7.85 g/cm³) divided by 1000. For a 50 NB medium-class pipe (OD 60.3 mm, t 3.6 mm), the computation matches IS 1239 at 5.03 kg/m.

What is the MS pipe unit weight for a 2 inch pipe?+

The weight of a 2 inch / 50 NB MS pipe in IS 1239 Class A (Light) is 4.08 kilogram per metre, Class B is 5.03 kg, and Class C is 6.19 kg. The same size weighs 5.44 kg/m in ASME Schedule 40. Class or schedule must be indicated on PO.

What is the weight of a 4 inch MS pipe per metre?+

A 4 inch / 100 NB MS pipe weighs 9.75 kg/m in Class A, 12.10 kg/m in Class B, and 14.40 kg/m in Class C per IS 1239. In ASME Schedule 40, the weight is 16.07 kg/m and in Sch 80 it is 22.32 kg/m.

What is the difference between Class A, B, and C MS pipe weight?+

A particular NB has the same outer diameter for all three classes. Only wall thickness differs: Class A (Light) is thinnest, Class B (Medium) is standard, and Class C (Heavy) is the thickest. Thickness increases weight per metre: 50 NB has 4.08, 5.03, and 6.19 kg/m.

What is the density of MS pipe?+

The density of MS pipe is 7.85 g/cm³ (7,850 kg/m³). This is the BIS and ISO reference value for mild steel and is the basis for every theoretical weight in this chart. Galvanised iron (GI) pipes use the same base density but add roughly 1–3 % for the zinc coating.

What is the Jindal C-class pipe weight chart?+

Section 05's IS 1239 Class C table matches the Jindal C class pipe weight chart. 50 NB Jindal C-class weighs 6.19 kg/m, 100 NB 14.40 kg/m, and 150 NB 21.20 kg/m. These values apply to all BIS-licensed Indian mills, including Jindal, Tata, and Apollo.

What is the MS pipe weight tolerance?+

According to IS 1239 Part 1: 2004, Class A (Light) has a weight tolerance of −8%, whereas Class B (Medium) and Class C (Heavy) have −10%. This means a 100-metre Class B order with a chart weight of 503 kg can be delivered between 452.7 kg and 503 kg and be standard-compliant.

What is the weight of a 6 metre MS pipe?+

Multiply the kg/m value from the chart by 6. For example, 50 NB Class B at 5.03 kg/m × 6 m = 30.18 kg per length. For 100 NB Class B at 12.10 kg/m × 6 m = 72.60 kg per length. The kg-per-6-metre values are listed in the Class A, B, and C tables above.

Is MS pipe weight the same as GI pipe weight?+

Almost. Zinc-coated MS pipe is galvanised iron. Chart values apply to both base steel dimensions and IS 1239. Zinc contributes 1–3% weight, depending on coating thickness. Most procurement estimates weigh GI and MS identically; see Section 12's GI pipe weight table for deliverables.

What is the MS Schedule 40 weight chart used for?+

International project designs, oil and gas documentation, and export purchase orders use ASME B36.10 MS pipe Schedule 40 weight chart. Schedule 40 resembles IS 1239 Class B, wall thicknesses differ. To avoid obtaining the wrong wall thickness, specify on the PO.

What is the MS hollow circular pipe weight chart?+

The MS hollow circular pipe weight chart is the same as the MS round pipe weight chart and follows IS 1239. See Section 11 of this page for the most-stocked round pipe sizes from 15 NB to 100 NB, or refer to the master IS 1239 chart in Section 02 for the full range.

What is the MS black pipe weight chart?+

MS black pipe is an uncoated mild steel pipe (no galvanising, no paint), and its weight chart matches IS 1239. "Black" refers to the black mill-scale surface finish, not a standard. Use Section 02's master IS 1239 chart for MS black pipe weights.
