Understanding Pipe Dimensions: Your Go-To Reference Tables
July 28th, 2025 by Amanda Schumann
When working with steel piping—whether for construction, manufacturing, or infrastructure—accurate dimensions are critical. That’s why we’ve made it easy to access comprehensive Steel Pipe Dimension Tables in the Technical References section of our website.
Why These Tables Matter
Steel pipe dimensions aren’t just about diameter. They include wall thickness, weight per metre, and compliance with standards like ANSI [ASTM]. These values are essential for:
- Design calculations
- Material selection
- Cost estimation
- Compliance with engineering codes
What You’ll Find in Our Tables
Our dimension tables cover a wide range of pipe types and standards, including:
- Nominal Bore Size and Outside Diameter (OD)
- Wall Thickness (Schedule 10 to XXS)
- Weight per Metre for each size and schedule
- Measurements are in metric
- Standard compliance references
Each table is clearly formatted for quick reference, whether you’re in the office or on-site.
How to Use Them
You can access the tables directly from our Technical References section. They’re ideal for:
- Engineers drafting specifications
- Procurement teams comparing materials
- Students learning about piping systems
- Anyone needing quick, reliable data
Bookmark It for Future Use
We recommend bookmarking the page or downloading the tables for offline access. They’re updated regularly to reflect the latest standards and industry practices.
