What this calculator does
Estimates PE pipe weight per metre and total weight from outside diameter, SDR, length and quantity, for PE100, PE100-RC, PE80 and multi-layer PE pipe. Also returns wall thickness, internal diameter, weight for one length, weight per 6 m and 12 m, internal capacity in litres and an optional water-filled total. Both theoretical and estimated handling kg/m are shown.
Who it is for
UK utility contractors, water main and gas main installers, civils estimators, plant operators, site supervisors and engineers planning lifting, transport, storage or site movements of PE pipe — including large-diameter trunk-main projects up to 2000 mm OD.
How to use it
Pick the PE material (PE100, PE100-RC, PE80 or multi-layer). Choose the outside diameter from the standard list, or tick 'Use custom outside diameter' to enter a value in mm. Pick the SDR rating, set the length per pipe in mm, cm, m or inches (or use the 6 m / 12 m / 13.5 m quick buttons) and the quantity. Click 'Calculate pipe weight' for weight per metre, total weight, wall thickness, internal diameter, per-length figures, internal capacity (litres) and an optional water-filled estimate.
How the calculation works
Wall thickness (mm) = OD ÷ SDR. Internal diameter (mm) = OD − 2 × wall thickness. Wall cross-section area (m²) = π/4 × ((OD/1000)² − (ID/1000)²). Theoretical weight per metre (kg/m) = wall area × material density. Estimated handling weight (kg/m) = theoretical × 1.04 to allow for typical manufacturing tolerance and surface effects. Total weight = handling kg/m × length per pipe × quantity. Internal capacity per metre (litres) = π × (ID/2 in m)² × 1000. Water-filled total ≈ pipe weight + total litres × 1 kg. Densities used: PE100, PE100-RC and multi-layer = 960 kg/m³; PE80 = 950 kg/m³.
Worked example
1200 mm OD PE100, SDR 11, 12 m length, quantity 1. Wall thickness = 1200 ÷ 11 ≈ 109.1 mm. ID = 1200 − 2 × 109.1 ≈ 981.8 mm. Wall area ≈ 0.374 m². Theoretical weight ≈ 358.9 kg/m. Estimated handling ≈ 373.3 kg/m (× 1.04). Weight for one 12 m length ≈ 4,479 kg, or about 4.5 tonnes. Internal capacity ≈ 757 L per metre, or about 9,080 L per 12 m length — confirms that any large-diameter PE lift needs heavy lift gear and a documented plan.
Assumptions and limitations
- Densities: PE100 / PE100-RC = 960 kg/m³, PE80 = 950 kg/m³, multi-layer / barrier PE = 960 kg/m³ (estimate only — confirm with manufacturer)
- Estimated handling factor of 1.04 applied to the theoretical weight per metre to allow for manufacturing tolerance and surface finish
- Wall thickness uses the simple WT = OD / SDR relationship
- Coupler, fitting, end-cap and packaging weights are not included
- Internal capacity uses the calculated internal diameter and ignores fittings, joints and any liner or barrier layer
- Water-filled weight assumes 1 kg per litre and is a planning estimate only — it does not replace engineering, lifting or temporary works checks
- Coil-form pipe (small diameters) typically ships in long coils — the per-length figure assumes straight stick lengths
- Sizes 1400 mm, 1600 mm, 1800 mm and 2000 mm are extended specialist sizes, not held by every supplier — always confirm availability and density before ordering
- SDR values shown (7.4 to 51) cover the common range; not every OD × SDR combination is manufactured
- This is a planning estimate, not a certified weight for lifting, LOLER calculations or load assessments
Frequently asked questions
How do I calculate PE pipe weight?
Work out the wall thickness as outside diameter divided by SDR. Subtract twice the wall thickness from the outside diameter to get the internal diameter. The wall cross-section area in square metres is π/4 multiplied by (OD² − ID²) in metres. Multiply that area by the material density (around 960 kg/m³ for PE100) to get theoretical weight per metre. Multiply by length and quantity for the total. This calculator does all of that automatically and also adds a small handling allowance because manufacturer charts usually use the maximum permitted tolerance.
What does SDR mean on PE pipe?
SDR stands for Standard Dimension Ratio. It is the outside diameter of the pipe divided by the wall thickness. A lower SDR means a thicker wall and a higher pressure rating. SDR 11 PE100 pipe, for example, has a wall roughly one eleventh of its outside diameter and is commonly used for higher pressure water mains.
How much does 1200 mm SDR11 PE100 pipe weigh?
A 1200 mm OD PE100 SDR11 pipe has a wall thickness of about 109.1 mm. Using a conservative handling estimate, that works out at around 373 kg per metre. A standard 12 metre length therefore weighs around 4.5 tonnes, which is firmly in mechanical handling and lifting plan territory.
Does this calculator show wall thickness?
Yes. Wall thickness is shown as a prominent result, calculated from the outside diameter divided by the SDR rating. It is one of the most useful figures for fusion planning, fitting selection and supplier cross-checks.
Does this calculator show internal diameter?
Yes. The approximate internal diameter is shown as a prominent result. It is calculated as the outside diameter minus twice the wall thickness, and is useful for estimating internal capacity, flow assumptions and joint compatibility.
Can it estimate water-filled pipe weight?
Yes. The result block includes an optional water-filled estimate built from the internal capacity (litres) and 1 kg per litre of water. This is shown as a planning context only — it does not replace engineering, lifting or temporary works checks for filled pipe.
Can I use this for 2000 mm PE pipe?
Yes. The dropdown includes extended specialist sizes of 1400 mm, 1600 mm, 1800 mm and 2000 mm. These sizes are not stocked by every supplier, so always confirm availability, wall tolerance and manufacturer weight before specifying or ordering. The calculator clearly flags pipe in this range as extended large-diameter PE.
Why do manufacturer pipe weights vary?
Manufacturer weight charts often quote the upper end of permitted dimensional tolerances, use slightly different densities and may include co-extruded outer skins or barrier layers. Two pipes of the same nominal size from different manufacturers can therefore differ by a few percent in real weight. Always check the supplier's own data sheet before lifting or transport.
Can I use this calculator for lifting plans?
No. It can help with early planning, but lifting and handling decisions must be checked against supplier or manufacturer data and the site lifting plan.
Is this official manufacturer data?
No. This is a free, formula-based estimating tool. It is not affiliated with or endorsed by any pipe manufacturer or supplier. Results are estimates for planning only and should be verified against your pipe supplier's published data and the site lifting plan.

Sources and references
Common UK utility PE pipe ranges: mainstream UK polyethylene pipe ranges for water and gas distribution typically cover common utility sizes from 20 mm up to 1200 mm OD across SDR 11 and SDR 17, with other SDR classes available subject to manufacturer and volume. Published PE100 pipe weight charts: industry weight charts for PE100 cover the common utility range and extend to large-diameter pipe up to 1600 mm OD across SDR classes from SDR 7.4 to SDR 51. Extended large-diameter PE100 technical tables: specialist PE100 manufacturers publish technical data for extended large-diameter pipe up to around 2000 mm OD; availability and wall tolerances vary, so always confirm with the chosen supplier or manufacturer before specifying. Standard SDR / wall-thickness relationship: PE100 catalogues confirm SDR is defined as outside diameter divided by wall thickness, and list, for example, a 1200 mm OD pipe at SDR 11 / PN 16 with a wall thickness of 109.1 mm — the same value this calculator's formula returns.
