Most people don’t use a pipe diameter measuring tape. The reason is not that they don’t need one. The reason is that they don’t know how powerful it is. They don’t know what it can do for them. Just ask the people who use one every day:
- pipe installers
- plumbers
- pipeline inspectors
- pipeline installers and repairmen
- HVAC installers
- car mechanics
- boat mechanics
- oil and gas rig workers
- sport ball makers
They will tell you this: If you want to know the outside diameter of a pipe or any round object, just wrap the diameter tape around its circumference, and read the diameter on the tape. Simple. You don’t have to divide by pi. The best part of this: Even if the pipe is not perfectly round, the od diameter tape will give you the average outside diameter as if it were perfectly round.
