Making Sense of Diameter Types for PVC Pipe

Posted By John Houle on Apr 4, 2016

There are many different outside diameter (OD) types used for PVC pipe for various pressure and non-pressure applications. Not only are there several OD types, there are also associated abbreviations to add to the mix.

The topic can be approached in a logical manner by separating the pipe types for each standards organization and end-use application:

  • AWWA pressure pipe
  • ASTM pressure pipe
  • ASTM solid-wall sewer pipe
