How to Measure a Steel Pipe
publisherHELEN YANG
time2013/11/08
When people first start measuring pipes, they may be confused. After all, pipe sizes range from 1/16 up to 4, but these sizes don't seem to match with the actual dimensions of the pipe itself. In addition, male pipe pipes and female pipes are sized slightly differently. In order to measure either type of pipe accurately, you need to measure its OD (outside diameter) and compare it to a chart of pipe sizes.
Instructions
Measuring Male Pipes
- 1.Place the calipers of the micrometer around the part of the pipe that screws into the adjacent pipe.
- 2.Turn the micrometer screw until the calipers gently grip the pipe.
- 3.Look at the sleeve of the micrometer and take note of the measurement displayed.
4.Open the Plumbing Supply website. Look in the chart to find the measurement in column 2. Locate the thread (or pipe) size directly to the right of the cell you just identified.
