Metal & PVC Pipe weight

Regardless of schedule number, pipes of a particular size all have the same outside diameter (not withstanding manufacturing tolerances). The higher the schedule is, the thicker the wall thickness and the inside diameter (I.D.) is smaller.

Here is an example:

A 4 inch Schedule 40 pipe: outside diameter of 4.500 inches, wall thickness of 0.237 inches, with an inside diameter (I.D.) of 4.026 inches;

A 4 inch Schedule 80 pipe: outside diameter of 4.500 inches, wall thickness of 0.337 inches, with an inside diameter (I.D.) of 3.826 inches;
