HOW TO USE A PIPE CALIPER

HOW TO USE A PIPE CALIPER

Our Pipe Caliper is used for measuring both iron and copper pipes for figuring out the actual pipe size rather than just the outside diameter (OD).  A must have tool for every insulator, engineer, mechanic, draftsmen, etc.

HOW TO USE OUR PIPE CALIPER TO FIGURE OUT THE SIZE OF A PIPE

Installing pipe insulation is rather a simple and easy project that anyone can accomplish.  The good thing about a pipe insulation project is that the requirement for tools is limited to a sharp knife, a handful of PVC tacks, and a roll of ASJ tape.  The only problem that can go wrong is not knowing the size of the pipe you want to insulate!

 

IDENTIFYING YOUR PIPE:

The purpose of this page is not to discuss Nominal Pipe Size vs. Iron Pipe Size, or the inner diameter of your pipe, etc.  This page is intended to guide you through how to identify the size of your pipe for buying pipe insulation from BuyInsulationProducts.com online store.

There are basically two types of pipes you could be insulating:

1. Copper

2. Iron (and basically every other type of pipe including PVC, CPVC, Black, Schedule 40/80, etc.)

 

THE EASY WAY OUT:

For Copper pipes, the good thing is most of the new copper tubing is labeled with ink and sometimes etched with the tube size.  This makes identifying the size of your pipe very easy.  If you can identify the size of your copper pipe go to our Copper to Iron Conversion Page to see which insulation size to order.

For PVC or CPVC, these pipes are usually clearly labeled with the pipe size in inches.  If it says 3" PVC pipe, order 3 x 1 (or whatever insulation thicknesses needed).  The same goes for any other Iron or Black pipe that is labeled with the size, that is the size to order.

 

NO LABEL? NO PROBLEM:

Ok, so you are still reading after the last two paragraphs, so you looked really hard and unfortunately there is no size listed on the pipe (or it is not legible in many cases!).  In this situation, you really have three options:

1.  Measure the Outside Diameter of the Pipe: You can do this with a regular pipe guage (not a common tool for a homeowner) or with a Diameter MeasuringTapeOnce you get the Outside Diameter of the pipe, follow our Nominal Pipe Size to Outside Diameter Chart to see what insulation size to order.  It is NOT recommended to measure the Outside Diameter of a pipe with a standard measuring tape or ruler.  Measuring a curved object with a straight rule results in "guestimates" which results in the wrong insulation size being ordered, especially on smaller pipes where the outside diameter measurements are so close.

2.  Measure the Circumference of the Pipe:  Follow the steps on our Pipe Size Chart.

3.  Use our Easy To Use Pipe Caliper:  Our Pipe Caliper can tell you the size of your pipe in seconds which makes ordering insulation for jobs that have multiple pipes quick and accurate.

HOW TO USE OUR PIPE CALIPER:

From the image below, you can see that you simply put the pipe caliper around the pipe in question, and close the two wings (items 1 and 3) in tight to the pipe with the top of the caliper (2).

Our Pipe Caliper will provide the actual pipe size for both Iron Pipe Size and Copper Tubing Size.

Once all three points of the caliper are touching the pipe, read the pipe size number that shows on the caliper (see red points below).  For Copper Tubing sizes, simply go to our Copper to Iron Guide to see what insualtion size to order from our online store.  For IPS, simply order that size on our site.

Our Pipe Caliper is fast and easy to use for any pipe insulator on the job.
