Pipe Outside Diameter Tolerances & Ovality Example

6" Sch 40 has an outside diameter of 6.625" +/- 0.011", and it has an ovality tolerance of 0.070". This means that the diameter, if perfectly round, could be between 6.614" and 6.636", which is the +/- 0.011". This pipe at any diameter in this range could be pushed down so that it is oval shaped. The biggest diameter that you could measure minus the smallest diameter that you could measure could be up to 0.070" difference.

In the diagram below, the top pipe is shown at a perfectly round 6.625". The lower pipe is shown at its maximum ovality tolerance of 0.070". Measuring horizontally, the pipe is 0.035" greater than the perfectly round pipe. Vertically, the pipe measures 0.035" less than the perfectly round pipe.

6.66" (biggest diameter) - 6.59" (smallest diameter) = 0.07" (ovality)

If tighter tolerances or other unique specifications are required, please contact Available Plastics. Available Plastics is a custom extrusion company and can make almost any size pipe you need.
