AWWA Flange Dimension Charts
Identify which style flange you may need to fit your metal bellows or expansion joints by using our AWWA flange dimension chart below. We have arranged them based on the different psi classes, so referencing the chart is as simple as determining which class your pipe coincides with. Simply match your pipe size with the psi class, and you will be able to find the right specifications for the flange you need. If you find yourself needing assistance with these AWWA flange dimension charts or want to learn more about the many low-pressure, high-pressure, and engine exhaust flanges we offer for metal bellows or expansion joints, please contact us today.
