ERW Steel Pipe Weight Chart: Standard Sizes and Specifications
ERW steel pipes are among the most widely used steel pipes across water supply networks, industrial pipelines, construction projects, firefighting systems, scaffolding, and structural applications. Their dimensional accuracy, smooth surface finish, and cost-effectiveness make them a preferred choice for engineers, contractors, and infrastructure developers.
When selecting ERW steel pipes, understanding the pipe weight is crucial. The weight of a pipe directly impacts transportation costs, structural load calculations, material estimation, and project budgeting. This is where an ERW pipe weight chart becomes an essential reference tool.
This guide provides a detailed overview of ERW pipe specifications, standard sizes, weight calculations, and the complete ERW pipe size chart based on IS 1239 Part 1 standards for air and water applications.
What are ERW Steel Pipes?
ERW (Electric Resistance Welded) steel pipes are manufactured by rolling steel strips into a cylindrical shape and joining the edges through electrical resistance welding. Unlike seamless pipes, ERW pipes have a welded seam but offer excellent strength, dimensional consistency, and cost efficiency.
These pipes are commonly used for:
- Water transportation
- Air distribution systems
- Firefighting pipelines
- Agricultural irrigation
- Structural frameworks
- Industrial process piping
- Scaffolding and construction
Their widespread adoption is largely due to their uniform wall thickness and availability in various sizes and pressure classes.
Understanding ERW Pipe Specifications
According to IS 1239 Part 1 standards, ERW steel pipes are generally available in three categories:
Light Class Pipes
Light-weight pipes suitable for low-pressure applications where reduced weight and cost are priorities.
Medium Class Pipes
The most commonly used category, offering a balance between strength and weight.
Heavy Class Pipes
Designed for applications requiring higher pressure handling capabilities and enhanced durability.
The classification primarily depends on wall thickness, which directly affects the overall pipe weight.

| Nominal Bore (mm) | Nominal Bore (Inch) | Light (kg/m) | Medium (kg/m) | Heavy (kg/m) |
|---|---|---|---|---|
| 15 | 1/2" | 0.947 | 1.21 | 1.44 |
| 20 | 3/4" | 1.38 | 1.56 | 1.87 |
| 25 | 1" | 1.98 | 2.41 | 2.93 |
| 32 | 1¼" | 2.54 | 3.1 | 3.79 |
| 40 | 1½" | 3.23 | 3.56 | 4.37 |
| 50 | 2" | 4.08 | 5.03 | 6.19 |
| 65 | 2½" | 5.71 | 6.42 | 7.93 |
| 80 | 3" | 6.72 | 8.36 | 9.9 |
| 100 | 4" | 9.75 | 12.2 | 14.5 |
| 125 | 5" | — | 15.9 | 17.9 |
| 150 | 6" | — | 18.9 | 21.3 |
How to Calculate ERW Pipe Weight
The weight of a pipe can be calculated using the standard chart values.
Formula
Total Pipe Weight = Weight per Metre × Length of Pipe
Example 1
- Weight = 6.19 kg/m
- Length = 6 metres
Total Weight:
6.19 × 6 = 37.14 kg
Why Pipe Weight Matters in Engineering Projects
Understanding pipe weight is essential because it affects:
Structural Design
Heavier pipes impose higher loads on supports, racks, and foundations.
Transportation Costs
Pipe weight directly influences freight charges and logistics planning.
Installation Planning
Lifting equipment and manpower requirements depend on pipe weight.
Cost Estimation
Accurate weight calculations help determine project costs and material budgets.
Inventory Management
Weight-based calculations assist in stock planning and warehouse management.
