Steel Pipe Size Chart In Mm And Inches
Introduction
If you're in the construction or plumbing industry, you know how important it is to use the right size of steel pipes. Steel pipes come in different sizes, and it's essential to understand the dimensions to ensure that you use the correct size for your project. In this article, we'll discuss the steel pipe size chart in mm and inches.
The Basics of Steel Pipe Sizes
Before we dive into the details of the steel pipe size chart, let's first understand the basics. Steel pipes come in different sizes, and the size is determined by the outer diameter of the pipe. The outer diameter is measured in millimeters (mm) or inches.
Steel Pipe Size Chart in mm
Here's a table that shows the steel pipe size chart in mm:
| Nominal Size (DN) | Outer Diameter (OD) | Wall Thickness (WT) |
|---|---|---|
| 15 | 21.3 | 2.8 |
| 20 | 26.9 | 2.8 |
| 25 | 33.7 | 3.2 |
| 32 | 42.4 | 3.2 |
| 40 | 48.3 | 3.2 |
| 50 | 60.3 | 3.6 |
| 65 | 76.1 | 3.6 |
| 80 | 88.9 | 4.0 |
| 90 | 101.6 | 4.0 |
| 100 | 114.3 | 4.5 |
It's essential to note that the wall thickness can vary depending on the pipe's material and application. In the table above, we've used a standard wall thickness of 3.2 mm for pipes with a diameter of up to 50 mm and a wall thickness of 4.0 mm for pipes with a diameter of more than 50 mm.
Steel Pipe Size Chart in Inches
Here's a table that shows the steel pipe size chart in inches:
| Nominal Size (DN) | Outer Diameter (OD) | Wall Thickness (WT) |
|---|---|---|
| 1/2 | 0.84 | 0.109 |
| 3/4 | 1.05 | 0.113 |
| 1 | 1.315 | 0.133 |
| 1 1/4 | 1.66 | 0.14 |
| 1 1/2 | 1.9 | 0.145 |
| 2 | 2.375 | 0.154 |
| 2 1/2 | 2.875 | 0.203 |
| 3 | 3.5 | 0.216 |
| 4 | 4.5 | 0.237 |
| 5 | 5.563 | 0.258 |
Just like in the table for steel pipe sizes in mm, the wall thickness can vary depending on the pipe's material and application. In the table above, we've used a standard wall thickness for carbon steel pipes.
Conclusion
Understanding the steel pipe size chart in mm and inches is crucial when working in construction or plumbing. Using the right size of steel pipes ensures that your project is safe and up to code. Always consult the appropriate resources and professionals to ensure that you're using the correct size of steel pipes for your project.
