Determine pipe thread sizes - PlumbingSupply

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. Male threads:Measure the outside diameter of the large portion of the thread at "A"; Find figure nearest this How Can I Tell What Size Pipe I Have?! Clean Water Store IncThe circumference is the distance it takes to go around the pipe once. Remove any insulation from the pipe.

This is the "travel", and is the center to center length of pipe needed. How to Age Galvanized Pipe eHowGalvanized metal is treated to keep water or other materials from rusting or corroding the metal. This is an ideal material for pipes, since they are in constant contact with fluids. Zinc is used in the coating process, but it can be stripped away using a few methods. Once the zinc is stripped, you can age your galvanized pipes. How to Determine Pipe Size - PlumbingSupplyWhen mass production of pipe began, there was a need for standardization. In 1927, the American Standards Association which has since evolved into the American National Standards Institute (ANSI) convened a committee to standardize the dimensions of wrought steel and wrought iron pipe and tubing.

How to Measure Pipe and Fitting Sizes Zoro

Measure the Outside Diameter (OD) of your pipe or pipe fitting:Wrap a string around the pipe Mark the point where the string touches together Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference) NPS - 'Nominal Pipe Size' and DN - 'Diametre Nominal'Pipes are identified by "nominal" or "trade" names that are loosely related to the actual dimensions. For instance, a 2-inch galvanized steel pipe has an inside diameter of about 2 1/8 inches and an outside diameter of about 2 5/8 inches. In plumbing pipe size is referred to as nominal pipe size - NPS, or "Nominal Pipe Size". The metric Pipe Sizes - Mr. HardwareThe pipe has a slightly larger id measuring in at almost 1 5/8-inces. This rule applies to steel and PVC pipe. The OD of 1/2-inch galvanized pipe is about 7/8-inch and so is 1/2-inch PVC. 3/4-inch pipe measures 1-1/16 inches, 1-inch measures 1 5/16 inches and 1 1/4 inches measures 1 5/8 inches. These same rules apply to rigid copper plumbing.

  • Determine if your pipe has male or female threads or no threads. Threads are the little grooves on the ends of some pipes that help them fit together. Male threads are on the Convert your diameter to nominal size if its smaller than 14 inches (360 mm). If its 14 inches (360 mm) or more, you dont need to convert it, because the diameter will equal the Convert your measurement of internal or outside diameter to the appropriate nominal size. Nominal size is what the pipe will be called in the store. You can do this using a table. Measuring Pipes and Pipe FittingsYou can usually identify the kind of pipe just by looking at it:copper pipe is copper-colored metal, galvanized steel water pipe is gray, and plastic pipe for supply lines is usually tan (CPVC, suitable for hot or cold water) or white (PVC, suitable only for cold water). Some supply lines might be PEX flexible plastic tubing in red, white or blue.
