In industrial piping, size and weight aren’t just numbers—they’re critical for safe, efficient, and cost-effective operations. At IndustrialFlange.com, we provide exact weights and dimensions (Dims) for every flange we offer, so you know what you’re dealing with before a single bolt is turned.

Why Flange Weights and Dimensions Matter?

1. Load Calculations:

Knowing the exact weight of a flange is essential for designing supports, hangers, and pipe stress systems. Underestimating flange weight can lead to structural issues or system failure.

2. Fit and Clearance:

A flange that’s even a few millimeters off can cause misalignment or sealing problems. Dimensional accuracy is critical for bolting, gasket fit, and proper pipe mating.

3. Handling and Logistics:

Heavy-duty flanges—like 24″ or 36″ class 600—can weigh hundreds of pounds. Accurate weight data helps you plan for crane lifts, rigging, and shipping costs.

4. Compliance:

Industry standards (like ASME B16.5 or B16.47) have strict dimension tables. Using flanges that don’t meet those standards risks inspection failures or system incompatibility.

What’s Included in Flange Dimensional Data

For each flange size and class, we provide:

  • Outside diameter
  • Bolt circle diameter
  • Number and size of bolt holes
  • Hub diameter and thickness
  • Raised face or ring type joint dimensions
  • Overall flange thickness
  • Nominal and actual weights (lbs or kg)

These values vary by flange type—weld neck, slip-on, blind, socket weld, lap joint, or threaded—and by pressure class.

Example: 6” 150# Weld Neck Flange

  • Outside Diameter: 11 in
  • Bolt Circle Diameter: 9.5 in
  • Flange Thickness: 0.94 in
  • Weight: Approx. 17 lbs

Multiply this across a hundred flanges, and it’s easy to see why exact weights and dims are crucial.
