CAD / 3D Flange Drawings: Precision That Drives Performance

In the piping and flange industry, precision isn’t optional—it’s everything. That’s why CAD and 3D flange drawings are more than just technical visuals. They’re essential tools for engineers, buyers, and manufacturers who need clear, accurate data to design, verify, and install flanges correctly.

At Carbon Flanges, we support our clients not only with top-tier carbon steel flanges but also with the technical documentation they need to get the job done right.

Why CAD / 3D Drawings Matter

Eliminate Guesswork

2D and 3D flange drawings offer detailed visualizations of flange dimensions—OD, bolt circle, thickness, bore sizes, and more—before anything is machined or installed.

Speed Up Engineering Workflows

Engineers use CAD models to integrate flange designs directly into larger piping systems, saving time and reducing rework. With 3D models, interference checks and fitment issues are caught early.

Enable Accurate Customization

Need a non-standard flange size? A 3D drawing allows clients to review the design, verify specs, and approve custom jobs with full confidence.

Support Global Collaboration

When teams are spread across regions, standardized CAD files (.DWG, .STEP, .IGES, etc.) help everyone stay aligned, whether in procurement, fabrication, or QA.

Our CAD Drawing Capabilities

We provide 2D and 3D CAD drawings for the full range of flanges we offer:

Weld Neck
Slip-On
Blind
Threaded
Lap Joint
Socket Weld
Custom Flanges

All drawings follow ANSI, ASME, DIN, or custom spec standards and include full dimensional details, tolerances, and notes where applicable.

File Formats We Offer

2D Drawings: DWG, PDF
3D Models: STEP, IGES, STL

If you have specific format needs or want native files for certain CAD platforms (SolidWorks, AutoCAD, etc.), we can provide those too.

Requesting CAD / 3D Drawings

If you’re sourcing flanges from us, just mention your need for CAD support. Whether you’re planning a large project or verifying specs for a replacement, we’ll send accurate drawings to match.
