OD is the outside diameter of the pipe and is fixed for a given size. The NPS is very loosely related to the inside diameter in inches, but only for NPS 1/8 to NPS 12. For NPS 14 and larger, the NPS is equal to the outside diameter (OD) in inches.

2024年8月5日 · OD (Outer Diameter): This is the measurement from one external edge of the pipe to the opposite external edge. Think of it like measuring the total width of your pipe from the outside. ID (Inside Diameter): This type of diameter means the distance from one internal extreme of the pipe to the other internal extreme.

OD, ID, and Nominal Pipe Size are crucial for pipe selection. Knowing the differences ensures the right fit for your project and optimal performance.

Use our ANSI Pipe Schedule Chart to determine the nominal pipe size, wall thickness, weight and schedule designations of carbon and stainless steel pipes. Access our downloadable pipe schedule chart for accurate dimensions. Find the best …

Using the formula given below, you can calculate the Pipe Inside Diameter (ID) with the help of the Outside Diameter (OD) and Thickness of the pipe. Pipe ID = [Pipe O.D. – (2×Pipe wall thickness)]

To create a piping system designed to transport fluids or gases, pipes are connected to pipe nipples, flanges, fittings, and valves. Tubing is round, but can also be square or rectangular, as well as measured by wall thickness and outside diameter (OD). The outside diameter is exact meaning a 1.25" tube is exactly 1.25" at the OD.

2024年10月7日 · The Outside Diameter (OD) of a pipe refers to the distance across the outermost edge of the pipe. This measurement is crucial because it helps determine how much space the pipe will occupy. OD is also vital for calculating wall thickness, pressure capacity, and how the pipe will connect to other piping or components such as fittings and valves.

The OD is an essential specification for pipes as it provides a clear and consistent reference for fitting, welding, and laying out pipelines, regardless of the wall thickness of the pipe. Understanding the OD is crucial for several reasons:

Both the TPI (threads per inch) and OD (outside diameter) of the thread are required for positive identification of thread size because several sizes have the same TPI. All pipe thread types used in plumbing are specified by the American National Standard for pipe as accredited by the American National Standards Institute (ANSI).

Outside diameter (OD) is the physical size of the pipe, that is, the distance from the outermost face of the pipe. The relationship between the OD and the “Nominal Pipe Size” is quite important when selecting fitting, flanges, and valves.
