Pvc Pipe Conversion Chart For instance you might assume a pipe with od (outer diameter) of 1.660" is a 1 1 2" size pipe when in fact it is 1 1 4" size. that's why using a chart and understanding how pvc pipe sizes are measured is important. many pvc users think that 2" size pipe measures 2" exactly in diameter. actually, 2" is just the nominal pipe size meaning it is. The most straightforward way to determine the size of a pvc pipe is to measure its outer diameter (od). use a measuring tape or a caliper to measure the circumference of the pipe and divide the result by π (3.14). for instance, if the circumference is 12 inches, the od is 12 3.14 = 3.8 inches.
How To Measure Pvc Pipe For Fittings At John Porter Blog 2. measure the pipe outer & inner diameters. to determine the size of your pvc pipe, you can measure both the outside diameter (od) and inside diameter (id). keep in mind that the inside diameter (id) is not exact, but usually very close. please refer to the table below to help you identify your pvc pipe size. For instance, let’s say you wrapped your lucky shoelace around the pipe and marked the circumference on the shoelace. comparing your shoelace to a measuring tape, you found the length of the string circumference is almost 7 1 2″. 7 1 2″ ÷ pi (or 3.1415) = 2.38″ outside diameter. an od of 2.38″ is a 2″ nominal pipe size. The od for 1 2" pvc pipe is 0.840" and the od for 3" pvc pipe is 3.500". if the nominal size is the id, then that means 1 2" pvc pipe walls are .170" thick and 3" pvc pipe walls are 0.250" thick. the wall thickness continues increasing as the pipe gets larger. for a downloadable version of this guide, click here. shop schedule 40 pipe. Measuring nominal pipe size (nps) the nominal pipe size (nps) is a standardized designation that represents the approximate od of the pipe. it is often used in place of the od when specifying pipe sizes. the nps is typically expressed in inches, with the most common sizes being 1 2″, 3 4″, 1″, 1 1 2″, and 2″.

Three methods to measure pipe diameter. 1. using a diameter tape. a reliable method providing accurate measurements, especially for larger pipes like 8 inch or 6 inch diameter pvc pipes. this method also facilitates conversions between inches and millimeters. 2. vernier caliper or ruler. suitable for smaller pvc pipes, accurately measuring. The od is always larger than the size name due to the thickness of the pipe walls. for example, a 3 4" pvc pipe actually has an od of about 1.050 inches, and a 1" pvc pipe has an od of approximately 1.315 inches. to find the size of a pvc pipe, it's always best to measure the inside diameter (id) using a measuring tape or a ruler.
