Measuring flange size accurately is crucial for ensuring compatibility with pipes, gaskets, and other components in a piping system. At Udhhyog, we prioritize precision and offer expert guidance to help you choose the right flange for your requirements.
Why Accurate Flange Measurements Matter
Ensures Compatibility:
Avoids costly mismatches and installation issues.Enhances Sealing Efficiency:
Proper sizing helps achieve a leak-proof connection.Meets Industry Standards:
Ensures compliance with ASME, ANSI, or DIN norms.
Tools You’ll Need
- Measuring tape or caliper.
- Straight edge or ruler.
- Reference chart for flange dimensions (optional).
Step-by-Step Guide to Measure Flange Size
1. Measure the Outer Diameter (OD)
- Place the measuring tape or caliper across the widest part of the flange.
- Record the distance from one edge to the opposite edge.
2. Determine the Bolt Circle Diameter (BCD)
- Identify the center of two opposite bolt holes.
- Measure the distance between them to get the BCD.
3. Count the Number of Bolt Holes
- Note the total number of bolt holes evenly distributed around the flange.
4. Measure the Bolt Hole Diameter
- Use a caliper to measure the diameter of a single bolt hole.
5. Check the Flange Thickness
- Measure the distance between the front face and back surface of the flange.
6. Identify the Bore Size
- Measure the internal diameter of the flange’s central opening.
Explore Flanges with Standard Dimensions
Common Flange Standards
ASME/ANSI Flanges
- Used globally in various industries.
- Include specific dimensions for Class 150, 300, and higher pressure ratings.
