## Is DN internal diameter?

Nominal Diameter is also known as the mean or average outside diameter and is represented by DN. It is neither equal to the inner diameter (ID) nor the outer diameter (OD) of the pipe.

## Is DN inside diameter?

**What is DN in PVC pipe?**

DN refers to the nominal diameter of the pipe, which is the average of the outer diameter and the inner diameter. The value of DN=the value of De-0.5*tube wall thickness.

### How do you find the diameter of a pipe from the circumference?

How do I get diameter from circumference? Divide the circumference value by the number pi (π), or use the formula d = c/π .
