When specifying or ordering flanges, two details matter as much as material and pressure class: weight and dimensions. These aren’t just numbers—they determine everything from shipping costs to structural integrity to pipeline performance.

At Carbon Flanges, we provide exact weights and dimension data for every flange type we sell, helping engineers and procurement teams make smart, confident decisions.

Why Flange Weights and Dims Matter

  1. Installation Planning
    The weight of a flange impacts how it’s handled on-site. Knowing this upfront helps you prepare for lifting, rigging, or crane requirements—especially for large-diameter or heavy-duty flanges.
  2. System Fit and Flow
    Dimensions affect flow rate, pressure drop, and overall system layout. An incorrect thickness or bolt circle diameter can cause costly delays or failures.
  3. Shipping & Logistics
    For bulk orders, weight directly affects freight cost. Having accurate weight data helps avoid surprises and streamlines shipping estimates.
  4. Code Compliance
    Standards like ASME B16.5 or B16.47 define strict dimensional tolerances. Providing exact dims ensures your project stays within spec.

What We Provide

For every flange, we supply detailed weight and dimension data:

  • Outside Diameter (OD)
  • Bolt Circle Diameter (BCD)
  • Number and Size of Bolt Holes
  • Flange Thickness
  • Raised Face Height (if applicable)
  • Bore / ID
  • Weight per Piece (Kg or Lbs)

We cover all major standards:
✔ ASME B16.5 (½”–24”)
✔ ASME B16.47 (26”–60”, Series A & B)
✔ DIN, EN, BS, and more (on request)

Available as Download or PDF

We offer flange weight charts and dimension tables in easy-to-reference PDF format. These can be accessed per flange type or by pressure rating (150#, 300#, etc.).

Custom Requirements? No Problem.

If your project involves non-standard flange sizes or exotic materials, we’ll calculate the weight and dimensions for you based on your drawing or spec sheet.
