When you’re planning a piping job or replacing a flange, size and weight aren’t just numbers — they affect fit, safety, handling, and cost. At CustomFlanges.com, we make it easy to get the exact flange dimensions and weights you need to design smart and build right.
Why Flange Dimensions and Weight Matter
Flanges come in hundreds of variations — raised face, blind, slip-on, weld neck, threaded, and more. Each type has different dimensions based on pressure rating, size, and standard (ANSI, ASME, DIN, JIS, etc.).
Here’s why accurate dims and weights matter:
- Proper fit – Ensures compatibility with pipes, gaskets, and bolts.
- Load planning – Helps teams handle, lift, and install flanges safely.
- Shipping efficiency – Avoid surprises in freight weight and cost.
- Engineering accuracy – Supports stress analysis, layout, and flow design.
What We Provide
We supply clear, consistent flange data based on your needs — including:
- Outside diameter (OD)
- Bolt circle diameter (BCD)
- Number and size of bolt holes
- Flange thickness
- Hub dimensions (if applicable)
- Weight (in lbs or kg)
Need help identifying a flange? We can reverse-engineer from a photo, sample, or sketch.
Standard vs Custom
We carry standard flange dimensions per:
- ASME B16.5 (½” to 24″)
- ASME B16.47 Series A & B (26″ to 60″)
- DIN/EN, JIS, and other global standards
But we also fabricate custom flange sizes — oversized, odd bores, non-standard bolt patterns — and provide exact drawings with weight estimates so you’re never left guessing.
Sample Flange Weights (ASME B16.5, Carbon Steel)
| Size (NPS) | Class 150 | Class 300 | Class 600 |
|---|---|---|---|
| 2” | ~3.5 lbs | ~6.5 lbs | ~10 lbs |
| 4” | ~9 lbs | ~16 lbs | ~27 lbs |
| 6” | ~19 lbs | ~34 lbs | ~59 lbs |
| 12” | ~64 lbs | ~125 lbs | ~245 lbs |
Weights vary by material and flange type. Contact us for exact specs.
