Steel Pipe Weight Chart
Steel Pipe Weight Chart
Use this steel pipe weight chart to find the weight of steel pipes by size, outside diameter, wall thickness, and schedule. Whether you need to calculate the weight of a single pipe or estimate the total weight of a bulk order, the chart helps you get the figures you need quickly. It includes steel pipe weight per metre, weight per 6-metre or 12-metre length, and approximate metres per tonne. You can use these values to estimate material quantities, compare pipe sizes, and plan transportation and project costs. Simply select the relevant pipe dimensions and check the corresponding weight. For the most accurate estimate, make sure the pipe dimensions and material specifications match your requirements, as actual weight can vary slightly from theoretical values due to manufacturing tolerances.
What Are Steel Pipes?
Steel pipes are hollow cylindrical products made from steel, designed to transport liquids, gases, and steam or to support structural loads. They come in different diameters, wall thicknesses, and grades to meet the needs of construction, manufacturing, oil and gas, water supply, and other industries.
Steel pipes are commonly available as seamless or welded pipes, including ERW (Electric Resistance Welded) pipes. The right type depends on the working pressure, temperature, corrosion conditions, and intended application.
When choosing a steel pipe, its outside diameter, wall thickness, length, and material grade help determine its strength, capacity, and weight. A steel pipe weight chart makes it easier to calculate the weight per metre or per length, estimate material quantities, and plan purchasing and transportation costs.

How to Calculate Steel Pipe Weight
You can calculate steel pipe weight using two measurements: the outside diameter (OD) and wall thickness. Once you know these dimensions, use the appropriate formula to estimate the pipe’s weight per metre or per foot.
Metric formula (kg/m):
Weight = (OD − Wall Thickness) × Wall Thickness × 0.02466
Use OD and wall thickness in millimetres for carbon and alloy steel.
Imperial formula (lb/ft):
Weight = 10.69 × (OD − Wall Thickness) × Wall Thickness
Use both measurements in inches.
Example: A 2-inch Schedule 40 steel pipe has an OD of 60.3 mm and a wall thickness of 3.91 mm. Its approximate weight is:
(60.3 − 3.91) × 3.91 × 0.02466 = 5.44 kg/m
For stainless steel 304, use a factor of approximately 0.02491 instead of 0.02466.
Quick conversions:
- 1 kg/m ≈ 0.672 lb/ft
- 1 lb/ft ≈ 1.488 kg/m

Formulas (mm):
Why Actual Steel Pipe Weight May Differ
A steel pipe weight chart provides an estimated weight, but the actual weight can vary depending on a few factors:
- Wall thickness: Small variations in the pipe wall during manufacturing can change its overall weight.
- Pipe ends: Threading, bevelled edges, and sockets can slightly affect the final weight.
- Protective coating: Galvanising adds extra weight to the pipe.
- Material grade: Stainless steel grades, such as 316, may weigh differently from carbon steel due to differences in material density.
For preliminary cost estimates, you can allow a small margin for weight variations. For bulk orders, confirm the supplier’s weight calculation and billing method before placing the order. If billing depends on actual weight, ask whether the supplier uses weighbridge measurements or theoretical pipe weight.
Common Mistakes When Using a Steel Pipe Weight Chart
A steel pipe weight chart is useful for quick calculations, but choosing the wrong dimensions can lead to incorrect results. Watch out for these common mistakes:
- Ignoring the pipe schedule: The same nominal bore can have different weights depending on the schedule and wall thickness.
- Using the wrong material: Stainless steel and carbon steel may have different weights for the same pipe dimensions.
- Confusing Sch 40 and STD: These specifications do not always have the same wall thickness, especially in larger pipe sizes.
- Mixing measurement units: Check whether the outside diameter is listed in millimetres or inches before calculating.
- Ignoring the weight of water: When designing pipe supports, include the weight of the pipe, contents, insulation, and other fittings where applicable.
Steel Pipes for Industrial and Commercial Applications
Find steel pipes to suit your project requirements, with options in carbon steel, stainless steel, and alloy steel across a range of sizes, wall thicknesses, and schedules. These pipes serve various applications, including construction, oil and gas, power generation, fabrication, and industrial fluid transportation.
To request a quotation, share your required pipe size, schedule, material grade, and quantity. This information helps confirm product availability, estimated weight, and suitable specifications for your application.
For domestic and international orders, check the applicable material standards and documentation requirements before purchasing. EN 10204 3.1 material test certificates can help verify the chemical composition and mechanical properties of the supplied material. Always confirm certificate availability, delivery details, and weight-based billing terms when finalising your order.
