Understanding flange dimensions and weights is critical for proper planning, installation, and load management in piping systems. Dimension and weight tables are published by standard: ASME, DIN, EN and JIS.
What Flange Dimensions Include
Each flange type (Weld Neck, Slip-On, Blind, Threaded, Lap Joint, etc.) has a set of key dimensions:
- Outside Diameter (OD)
- Inside Diameter (ID)
- Bolt Circle Diameter (BCD)
- Number and size of bolt holes
- Flange thickness
- Hub dimensions (for weld necks)
- Raised face or ring type joint height (if applicable)
Flange Weight: Why It Matters
Flange weight affects:
- Support structure design
- Shipping costs
- Handling and installation
- Stress on piping systems
Weights vary based on flange type, size, pressure rating, and material.
Weight charts help engineers and buyers plan supports, shipping and handling.
Dimension & Weight Charts
Full tables by class are on Texas Flange's flange dimensions and weights page. They show:
- Dimensions by standard (ASME B16.5, DIN EN 1092-1, etc.)
- Weights per flange type, size, and pressure class
- Material-specific weights (carbon steel, stainless steel, etc.)
