Complete HDPE Pipe Size Chart: DN 20mm to DN 630mm as per IS 4984:2016
Full reference table of HDPE pipe outer diameter, wall thickness, SDR, pressure rating and weight per metre as per IS 4984:2016 for PE 100 grade SDR 11 pipes.
This article provides a complete HDPE pipe dimension reference based on IS 4984:2016. All values below are for PE 100 grade, SDR 11 — the most commonly specified combination for water supply in India.
Understanding the Dimensions
- OD (Outer Diameter): The outside diameter in mm — this is how HDPE pipes are sized in India (OD-based system)
- Wall thickness (e): Minimum wall thickness at the thinnest point of the pipe cross-section
- SDR: Standard Dimension Ratio = OD ÷ wall thickness. SDR 11 = relatively thick wall
- Pressure rating: PN 12.5 for PE 100 SDR 11 (same pipe is PN 10 for PE 80 SDR 11)
- Weight: Approximate weight per metre of pipe in kg

Coil vs Straight Lengths
| Size Range | Standard Form | Common Lengths |
|---|---|---|
| DN 16 to DN 63 | Coil | 50 m, 100 m coils |
| DN 75 to DN 160 | Coil or straight | 50 m coil or 6 m / 12 m lengths |
| DN 180 and above | Straight lengths | 6 m or 12 m lengths |
For borewell rising mains, DN 50mm to DN 110mm (SDR 11, PE 100) covers most Indian submersible pump configurations. For sprinkler mainlines, DN 63mm to DN 160mm (SDR 17, PN 6) is the standard range.
How to Order HDPE Pipes
Always specify the pipe using the IS 4984:2016 designation format: PE [grade] / PN [pressure] / DN [diameter] / SDR [ratio]. Example order: PE 100 / PN 12.5 / DN 110 / SDR 11 / IS 4984:2016. This ensures you get exactly what you need and can verify ISI certification.
Full IS 4984 Size Range
IS 4984:2016 covers DN 16mm to DN 2500mm. The table above covers the most commonly available sizes. Larger diameters (DN 710mm to DN 2500mm) are manufactured for major municipal and industrial projects on order, in five size groups: Group I (16–180mm), Group II (200–500mm), Group III (560–1000mm), Group IV (1200–2000mm), Group V (2250 & 2500mm).
