3 Inch Copper Pipe
A 3-inch copper pipe typically refers to the nominal pipe size (NPS) of the pipe, which represents its approximate inside diameter.
Copper pipe sizes are commonly measured using the Nominal Pipe Size (NPS) system, which assigns a nominal size based on the approximate inside diameter. However, it's important to note that the outside diameter (OD) can vary depending on the type of copper pipe being used.
For a standard Type L copper pipe, the outside diameter of a 3-inch pipe is approximately 3.125 inches (or 79.38 millimeters). The actual inside diameter (ID) will be slightly smaller due to the thickness of the pipe walls.
