HDPE Pipe Weight Chart, explained simply
PE100, PN 10, SDR 13.6, 110 mm — they sound technical, but they're just labels. Learn to read any HDPE pipe chart in a minute, and work out how heavy your order is before it arrives.
Find your pipe's weight
Pick a grade, pressure and size. The wall thickness, weight per metre and the total for your order update instantly.

- SDR = OD ÷ wall = 110 ÷ 8.1 ≈ 13.6 → rounds to the standard SDR 13.6
- Inside Ø ≈ OD − 2 × wall = 110 − 2 × 8.1 = 93.8 mm
- Wall range: Table 4, IS 4984:2016 as amended by Amendment 2
- Total = 2.667 kg/m × 300 m = 800 kg
Worked example: 300 m of 110 mm PE100 PN 10 → 2.667 kg/m × 300 = about 800 kg, with an inside diameter of ≈ 93.8 mm.
Five labels, in plain words
Every row on a pipe chart is built from the same few ideas. Poke at the controls below — they show what each number does to the pipe.
1 · Grade — PE63, PE80, PE100
The number after “PE” comes from the plastic's long-term strength (MRS). A stronger plastic holds the same pressure with a thinner wall — so a PE100 pipe at PN 10 uses less plastic, and weighs less, than PE80 at PN 10.
2 · PN — pressure in bar
Nominal pressure. 1 bar ≈ 10 m of water height. The standard offers PN 2, 2.5, 3.2, 4, 5, 6, 8, 10, 12.5, 16 and 20.
The maximum continuous pressure with water at 27 °C, worked out from the plastic's 50-year strength at 20 °C (MRS) with a design factor of 1.25.
3 · SDR — how thick the wall is
Standard Dimension Ratio = outside diameter ÷ wall thickness. Smaller SDR = thicker wall: heavier and higher pressure.
4 · Wall thickness — why two numbers?
No pipe is made to exactly one thickness, so the standard gives a minimum and a maximum. The wall must sit between them everywhere. Very small pipes have a 2.0 mm minimum.
5 · Weight — kg per metre
The plastic in one metre of pipe × its density (a little under 1 kg per litre — HDPE floats). You don't need to do the sum; the chart does it for you.
Grade, PN and SDR decide each other
Pick any two and the third is fixed. The standard's formula gives the pressure, rounded down to the nearest PN in the series (0.85 is a safety factor for water at 27 °C).

Is the chart weight the exact weight of every pipe?
No. It is a reference weight worked out from the standard's wall thicknesses — the standard itself prints no weights. Because the wall is allowed to vary between the minimum and maximum, the real weight of a pipe can be slightly different. Our quotation shows the weight we will supply.
Why is a PE100 pipe lighter than a PE63 pipe at the same pressure?
The stronger plastic needs less wall to hold the same pressure, so there is less plastic in every metre.
What does “IS 4984” mean?
It is the Indian Standard for polyethylene pipes for water supply. This guide follows IS 4984:2016 as changed by Amendment No. 2 (April 2022).
What changed in Amendment 2?
The wall-thickness table was replaced (many maximums moved up by 0.1 mm, and the smallest pipes now have a 2.0 mm minimum), PE100 SDR 41 is now rated PN 3.2 instead of PN 3, and 2250 mm and 2500 mm sizes were added. Amendment 1 (May 2018) had already corrected the 110 mm SDR 21 wall to 5.3–6.0 mm.
Can I use the weight to compare quotes?
Yes. Pipe is usually priced by weight, so compare the same size, grade and PN across suppliers. A thinner wall means less material and a lower price, but it may mean a lower pressure rating.
Where can I read the standard?
IS 4984:2016 and its Amendment No. 2 (2022) are published by the Bureau of Indian Standards (BIS). You can get them from BIS, and BIS also publishes the IS 4984 certification manual.
