When selecting the right flange for a piping system, two critical factors come into play: weight and dimensions. These numbers affect everything from pressure ratings and installation to shipping costs and structural support. We make it easy to access accurate flange weights and dims so you can move forward with confidence.

Why Flange Weights Matter

The weight of a flange isn’t just about shipping logistics—it impacts the entire system design. Heavier flanges require more support and influence load calculations for connected equipment.

  • Handling and Installation: Heavier flanges may need lifting equipment.
  • Structural Impact: Weight affects pipe stress and support brackets.
  • Cost: Material costs and freight charges increase with weight.

That’s why knowing the exact weight of each flange—based on size, type, and material—is essential.

Understanding Flange Dimensions

Flange dimensions determine how components connect, seal, and hold under pressure. Key dimensions include:

  • Outer Diameter (OD)
  • Bolt Circle Diameter (BCD)
  • Number and Size of Bolt Holes
  • Thickness
  • Raised Face or Flat Face height
  • Hub Dimensions (for weld neck and socket weld flanges)

These measurements vary depending on the flange type (weld neck, blind, slip-on, etc.) and the standard used (ANSI/ASME, DIN, JIS, etc.).

Standardized Dimensions and Weights

To streamline piping design, flanges follow standard dimension tables based on:

  • Nominal Pipe Size (NPS)
  • Pressure Class (150, 300, 600, etc.)
  • Material (Carbon Steel, Stainless Steel, Alloy, etc.)

These tables are essential for engineers and procurement teams looking to:

  • Ensure compatibility between components
  • Calculate material requirements
  • Estimate shipping loads
  • Meet compliance with industry specs
