Measure Pipe Size for Insulation

One of the most common questions we get  is “How do I know what size pipe I have so I can order pipe insulation?”

Easy Answer: Buy a Pipe Caliper

If you purchase a pipe caliper (or pipe guage), your life will be much easier when it comes to insulating your pipes.  Using the wrong size pipe insulation is never fun or easy, and it usually results in a bad outcome.  To ensure that you buy and install the correct size pipe insulation, you need to know the pipe size.

HOW TO USE THE PIPE CALIPER FROM BUY INSULATION PRODUCTS:

1. Open the legs of the pipe caliper and place it around the pipe in question
2. Push the legs of the pipe caliper closed so that each leg is touching the pipe as well as the mouth of the caliper
3. Read the pipe size (it will show Copper sizing (CWT) and Iron sizing (IPS)
4. If the pipe is copper use the CWT size, use the IPS for all other pipes.
