Introduction
Whether steel pipes are produced or used, it is necessary to know the weight of steel pipes of different sizes per foot. How to calculate? Knowing this can well estimate the weight of each steel pipe, and it is very clear what to use for loading and unloading during installation and transportation.
So how to calculate the weight of steel pipes specifically? For someone who is new to the steel pipe industry, it is very necessary to know this. So this article will mainly introduce how to calculate the weight of steel pipes per foot, and what is the calculation formula? I hope it will be helpful for those who are new to the industry.
It can mainly calculate the weight of steel pipes per foot by the outer diameter, wall thickness, production standards and raw materials of the steel pipe. Its units are mostly kilograms or pounds.
Why You Need to Know Pipe Weight
There are several reasons for knowing the weight of steel pipes per foot:
1. Material cost: According to its weight, the weight of the raw materials to be purchased can be roughly estimated.
2. Transportation: Knowing its weight can calculate how many feet of container to use for transportation.
3. Structural calculation: estimate the load-bearing capacity based on weight.
4. Project planning: avoid waste caused by over-purchasing.
Steel Pipe Weight Formula
There are two ways to calculate the weight of steel pipes:
Imperial units (pounds/foot)
Weight = 10.69 × (OD – WT) × WT
Note:
The unit is inches.
10.69: Density constant of steel (carbon steel)
Metric Units (kg/m)
Weight = (OD – WT) × WT × 0.02466 × 1000
Note:
The unit of outer diameter and wall thickness is millimeters.
0.02466: is the density factor (based on 7.85 g/cm3)
For example:
Weight of 2-inch Schedul 40 steel pipe:
Outer diameter = 2.375 inches, wall thickness = 0.154 inches
Weight = 10.69 × (2.375 – 0.154) × 0.154 = ~3.66 lbs/ft
What Is a Steel Pipe Weight Calculator?
The steel pipe weight calculator can be: calculator or online calculation software.
Many factories have weight tables corresponding to corresponding sizes, which can be obtained from suppliers if needed.
These calculators are widely used by:
Architectural Engineer Team
Manufacturer Team
Purchasing Team

Common Pipe Sizes and Weights (Schedule 40)
| Nominal Size | Outside Diameter (in) | Wall Thickness (in) | Weight (lbs/ft) |
|---|---|---|---|
| 1/2″ | 0.84 | 0.109 | 0.85 |
| 1″ | 1.315 | 0.133 | 1.68 |
| 2″ | 2.375 | 0.154 | 3.66 |
| 3″ | 3.5 | 0.216 | 7.58 |
| 4″ | 4.5 | 0.237 | 10.79 |
The above is the inner and outer diameters and weights of Schedule 40 steel pipe.
How to Use a Pipe Weight Calculator
1. Measure the outer diameter of the pipe.
2. According to the production standard, determine the wall thickness of the steel pipe.
3. Calculate according to the calculation formula.
4. Multiply the required number of meters to calculate the total weight.
Tips:
When calculating, ensure that the unit is unified and determine whether the raw material type is carbon steel pipe, stainless steel pipe or alloy steel pipe. Different materials have different densities.
Summary
To calculate the weight of the steel pipe, you first need to determine the production standard, size, inner and outer diameters, wall thickness and raw materials of the steel pipe. In this way, the weight per foot of the steel pipe can be calculated through the calculator.
If you don’t remember the calculation formula, you can search the Internet for the corresponding steel pipe weight calculator, which has a preset formula. Enter the corresponding data to estimate the weight of the steel pipe.
