When it comes to large diameter flanges, weight and dimensions aren’t just stats — they’re critical to project success. At Large Diameter Flanges, we give you precise, reliable data on every flange we manufacture, because we know that even minor discrepancies can create major issues in the field.
Why Accurate Flange Weights and Dimensions Matter
Flanges are heavy-duty components. In large-scale projects, small errors in size or weight can throw off alignment, create handling problems, or push shipping costs through the roof.
That’s why we provide detailed weight and dimension specs for:
- Standard and custom flanges
- All sizes — from 12″ to over 200″
- All classes — from 150 to 2500 and beyond
- All materials — carbon, stainless, and specialty alloys
What We Provide
For every flange, you’ll get:
- Outside Diameter (OD)
- Inside Diameter (ID)
- Bolt Circle Diameter
- Number and size of bolt holes
- Thickness
- Weight (in pounds or kilograms)
Whether you’re loading a truck, designing supports, or estimating shipping costs, you’ll have the numbers you need — no guesswork.
Built for Engineers, Buyers, and Contractors
Our dimensional data helps:
- Engineers verify fit before fabrication
- Buyers spec out the right flange the first time
- Contractors avoid rework and field delays
We base all dimensions and weights on current ASME/ANSI standards unless you need a custom spec. We can also provide 3D models and CAD drawings alongside dimensional sheets for deeper technical insight.
Need Custom Flange Specs?
Got a non-standard flange? No problem. Our team can build to spec and provide accurate weight and dimension data before production. That helps you plan better — and avoid surprises later.
