Flange Weights and Dimensions

When planning any piping system, knowing the exact weights and dimensions of your flanges is critical. We make it easy to access reliable flange weight and dimension data to keep your projects moving smoothly.

Why Flange Weights and Dimensions Matter

• Load Calculations: Flange weights are crucial for calculating the load on pipes, supports, and equipment.
• Space Planning: Knowing the exact outside diameter, bolt circle diameter, and thickness helps ensure everything fits during installation.
• Shipping and Handling: Accurate weight information is necessary for logistics planning and shipping cost estimates.
• Compliance: Correct dimensions guarantee that your flanges meet industry standards like ASME B16.5, DIN, and others.

Key Flange Dimension Terms

• Outside Diameter (OD): Total width of the flange.
• Bolt Circle Diameter (BCD): The circle on which bolt holes are centered.
• Thickness (T): Overall thickness of the flange.
• Raised Face (RF) Height: The thickness of the raised portion where the gasket sits.
• Number and Size of Bolt Holes: Determines bolting compatibility.

Typical Flange Types We Provide Data For

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

Available in all standard pressure classes (150, 300, 600, 900, 1500, and 2500) and material grades.

Standardized Data You Can Trust

Our flange dimensions and weights conform to:

• ASME B16.5
• ASME B16.47 Series A and B
• DIN EN 1092-1
• API 6A (for special oilfield applications)

Custom Needs? No Problem

If you need custom flange dimensions or weight estimates for a special application, we can produce precise CAD models and detailed spec sheets.
