The nominal diameter of metal pipes is classified based on the outside diameter of the pipe. The sizes range from small to large, with the smaller diameters being used for residential or light commercial plumbing, and larger diameters used for heavy-duty industrial applications.
The classifications start at 1/8 inch for the smallest pipes and go up to 72 inches for the largest pipes. They are typically measured in fractions of an inch, with each size increment representing a slightly larger outside diameter.
The precise sizing of pipes is important to ensure that they can safely carry fluid or gases without experiencing issues such as leaks or pressure buildup. As a result, manufacturers carefully adhere to industry standards when producing pipes to ensure they meet the required specifications.
Overall, the classification of nominal diameters for metal pipes is straightforward and helpful for anyone looking to select the correct size for their project.
