How can find 1 to10 inch pipe OD?

To find the outer diameter (OD) of a pipe ranging from 1 to 10 inches, you can refer to standard pipe size charts, which specify the OD for different nominal pipe sizes. For instance, a 1-inch nominal pipe typically has an OD of 1.315 inches, while a 10-inch nominal pipe has an OD of 10.750 inches. Additionally, you can measure the pipe directly using a caliper or tape measure if you have access to the physical pipe.
