Ductile Iron Pipe Weight Chart (DN100–DN2000)

Introduction

When engineers and project managers need fast and reliable data, a ductile iron pipe weight chart is often more practical than manual calculations.
Weight charts provide a clear reference for transport planning, installation design, and preliminary cost estimation, especially during bidding and early-stage engineering.

This page presents a typical ductile iron pipe weight chart covering DN100 to DN2000, along with explanations on how to read the data and when charts should be used instead of formulas.

For calculation methods and formulas, please refer to
How to Calculate Ductile Iron Pipe Weight (Formulas & Examples).

1. How to Read a Ductile Iron Pipe Weight Chart

A standard ductile iron pipe weight chart usually shows:

• Nominal Diameter (DN)

• Wall thickness class (K7 / K9 / K12 or equivalent)

• Pipe weight per meter (kg/m)

• Sometimes pipe weight per length (e.g. per 6 m pipe)

Important notes:

• Weights normally refer to metal weight only

• Cement lining and coatings are not included

• Socket (bell) weight may be listed separately or excluded

2. Ductile Iron Pipe Weight per Meter (DN100–DN2000)

Below is a typical reference chart based on common ISO / EN practice and average wall thickness values.

⚠️ Actual weights may vary slightly by manufacturer and standard.

3. Typical Weight per Pipe Length

Ductile iron pipes are commonly supplied in 5.5 m or 6 m lengths.

Example:

• DN300 K9 pipe

• Weight ≈ 65 kg/m

• 6 m pipe ≈ 390 kg (metal only)

Socket weight must be added separately when calculating:

• Lifting loads

• Container loading

• On-site handling requirements

4. Why Weight Charts Show Ranges Instead of Fixed Values

You may notice that pipe weight charts often show ranges, not exact numbers.

This is because:

• DN is a nominal size, not an exact dimension

• Wall thickness tolerances are allowed by standards

• Socket geometry varies by joint design

• Different manufacturers adopt slightly different practices

For final engineering and logistics decisions, manufacturer-certified weight tables should always be used.

5. Socket Weight Considerations

Socket (bell) weight is usually:

• Excluded from kg/m values

• Listed separately in product catalogs

Engineering observations:

• For DN800 and above, socket weight can add 5–12% to total pipe weight

• For DN1200+, socket weight can exceed 200 kg per pipe

Ignoring socket weight is a common mistake in container loading calculations.

6. When to Use a Weight Chart vs Calculation Formula

Use a Weight Chart when:

• Preparing tenders or budget estimates

• Planning transportation capacity

• Making quick engineering comparisons

Use Calculation Formulas when:

• Exact wall thickness is specified

• Custom pipe lengths are required

• Verifying manufacturer data

7. Engineering Notes for Transportation and Handling

Pipe weight directly affects:

• Crane and forklift capacity

• Sling and lifting point design

• Container floor load limits

• On-site safety procedures

For large diameters:

• DN1000+ pipes often require special lifting frames

• Weight distribution including socket must be considered

8. Frequently Asked Questions (FAQ)

Q1: Are weight charts accurate enough for container loading?

Weight charts are suitable for initial planning.
For actual container loading, always use manufacturer-certified pipe weights.

Q2: Do weight charts include cement lining?

No.
Most charts show metal weight only. Lining weight must be added separately.

Q3: Why do different suppliers show different weights for the same DN?

Differences come from:

• Wall thickness tolerances

• Joint and socket design

• Applicable standards (ISO / EN / AWWA)

Q4: Is heavier ductile iron pipe always stronger?

Not necessarily.
Strength depends on wall thickness class, material properties, and installation conditions, not weight alone.

9. Conclusion

A ductile iron pipe weight chart provides a fast and practical reference for engineers, contractors, and procurement teams.

By understanding:

• Weight per meter by DN

• The role of wall thickness classes

• The impact of socket weight

you can make better decisions in transportation, installation, and project planning.
