What is difference between nominal diameter of a pipe and bore of pipe and also defined the nominal diameter of pipe and tube how you differentiate both?

bore of the pipe is the internal diameter of pipe but the nominal diameter of pipe is the dia of a circle which is draw through a point which is situates at exactly half of the thickness of pipe or we can say that (outer dia of pipe- thickness of pipe )=nominal bore of pipe.

What is is the OD of a 40 inch nominal bore blak steel pipe?

The outside diameter (OD) of a 40-inch nominal bore black steel pipe is typically 40 inches, as the nominal size refers to the approximate internal diameter of the pipe. However, the actual OD for standard pipe sizes can vary; for a 40-inch nominal bore, the standard OD is approximately 42.16 inches according to the American National Standards Institute (ANSI) specifications. This discrepancy is due to the wall thickness of the pipe, which is accounted for in the nominal size.


What is nb for flange?

In the context of flanges, "nb" typically refers to the nominal bore, which is the nominal diameter of a pipe or fitting. It indicates the internal diameter of the pipe and is used to standardize measurements for flanges, ensuring compatibility between different components in piping systems. The nominal bore is important for determining the appropriate size and type of flange needed for a specific application.


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.
