Getting accurate weight specifications for buttweld pipe fittings isn't just about numbers on paper—it's about making smart decisions that affect your entire project's success. Whether you're calculating shipping costs, planning crane lifts, or designing pipe supports, having the right buttweld pipe fittings weight chart in kg, mm, PDF format can save you from costly surprises down the line.
Why Buttweld Pipe Fittings Weight Chart Matters More Than You Think
Every project manager knows that moment when reality hits the budget. You've ordered your fittings, everything looks good on paper, then the freight bill arrives. Or worse, your structural engineer calls asking why the pipe support calculations don't match the actual loads. This is where having detailed weight charts becomes your best friend.
Buttweld fittings aren't created equal. A Schedule 40 carbon steel elbow weighs significantly different from its stainless steel cousin, and don't get me started on the exotic alloys. The weight difference between materials can make or break your project economics.
Chart 1: Carbon Steel Buttweld Fittings (ASTM A234 WPB) - Schedule 40
Size (NPS) | Size (mm) | 90° Elbow (kg) | Tee (kg) | Reducer (kg) | Cap (kg) |
1/2" | 15 | 0.18 | 0.25 | 0.20 | 0.08 |
1" | 25 | 0.45 | 0.62 | 0.48 | 0.18 |
2" | 50 | 1.45 | 2.05 | 1.58 | 0.58 |
4" | 100 | 5.82 | 8.45 | 6.38 | 2.15 |
6" | 150 | 12.85 | 18.65 | 14.25 | 4.85 |
8" | 200 | 22.45 | 32.85 | 24.75 | 8.45 |
12" | 300 | 52.85 | 78.25 | 58.95 | 19.85 |
Chart 2: Stainless Steel 316L Buttweld Fittings - When Corrosion Matters
Size (NPS) | Size (mm) | 90° Elbow (kg) | Tee (kg) | Reducer (kg) | Cap (kg) |
1" | 25 | 0.49 | 0.67 | 0.52 | 0.19 |
2" | 50 | 1.57 | 2.21 | 1.71 | 0.63 |
4" | 100 | 6.29 | 9.13 | 6.89 | 2.32 |
6" | 150 | 13.88 | 20.14 | 15.39 | 5.24 |
8" | 200 | 24.25 | 35.48 | 26.73 | 9.13 |
12" | 300 | 57.08 | 84.51 | 63.67 | 21.44 |
The Real Cost of Going Stainless
Here's something most people don't calculate upfront: that 316L stainless steel fitting isn't just 30% more expensive to buy—it's also about 8-10% heavier. When you're shipping containers overseas or designing structural supports, those extra kilograms add up fast. Smart procurement teams factor this into their total cost calculations.

Size | Material | 90° Elbow (kg) | Tee (kg) | Density Factor |
4" | A234 WPB | 8.34 | 12.13 | 1.00 |
4" | 316L SS | 9.01 | 13.10 | 1.08 |

How B2B Marketplace Platforms Changed the Game
The digital transformation hit the pipe fittings industry hard, and frankly, it was about time. Gone are the days of calling five different suppliers for weight specs. Modern B2B marketplace platforms now integrate weight databases directly into their quotation systems. Companies like pipex.ai have made it possible to get accurate shipping calculations within minutes, not days.
What Schedule 80 Really Means for Your Wallet
Schedule 80 fittings pack roughly 40-60% more steel than Schedule 40s. That's not just engineering—that's economics. When you're specifying high-pressure systems, you need to budget for both the material premium and the transportation costs. A 12-inch Schedule 80 elbow can weigh nearly 80 kilograms compared to 53 kilograms for Schedule 40.
Getting Your Documentation Right
Most project specs now require weight charts in PDF format with full material traceability. The buttweld pipe fittings weight chart becomes part of your project documentation package, and auditors love seeing this level of detail. It shows you've done your homework.
Critical Considerations for Project Success
Weight miscalculations during the specification phase create cascading problems throughout project execution. Structural engineers need accurate load data for pipe support design, while logistics teams require precise weights for transportation planning and crane capacity calculations.
Modern procurement departments increasingly rely on detailed weight documentation to meet quality assurance requirements. The integration of comprehensive weight data into platforms like pipex.ai streamlines the selection process while ensuring compliance with project specifications.
Understanding material density variations becomes crucial when evaluating alternative alloys. These weight charts serve as essential reference tools that help engineers make informed decisions based on both performance requirements and economic considerations throughout the project lifecycle.
