Celebrate Pi Day 2019 With A Diameter Tape Measure

Pi Day is March 14. This year you can help celebrate by answering the question at the bottom.

Pi is the constant ratio of a circle’s circumference to its diameter, no matter what size the circle is. This is useful knowledge when you work with water pipes or oil or gas pipelines, and you need to replace part of it. You can measure the circumference and divide by pi. But there’s an easier way to do that.

Diameter Tape (pi Tape)

Let a Lufkin Diameter tape measure do it for you. You just wrap it around the pipe, and read the diameter. Mathematicians call pi an irrational number, since it goes on for an infinite number of decimal places, but using a diameter tape is a very rational and easy way to find the diameter of a pipe.

3 Easy Steps to Use a Pipe Diameter Tape Measure

This time, we won’t get into the geometry theory of pi that we had in high school. The magic of a pipe diameter tape measure is its simplicity of use. Here are the 3 steps to find the diameter of a pipeline:

  1. Clean the pipe surface. Soil and any other contamination, of course, will make the pipe seem bigger than it really is.
  2. Wrap the diameter tape around it, with the diameter scale visible to you.
  3. Simply read off the tape. This will be the diameter, even though the tape is wrapped around the circumference. That’s all!

Some things to watch for…..Some OD tapes (diameter tapes) are marked in 100ths of an inch. Some are marked in 64ths of an inch. On the 64ths of an inch tape, 32/64 would be 1/2″. 16/64 would be 1/4″. 24/64 would be 3/8″. For convenience, you can use a magic marker to mark some of these common, but confusing measurements.

A diameter tape measure can save you a lot of time and frustration when you want to find the OD (outside diameter) of a pipe, post, or tree. This special tape has the inch scale (or metric scale) stretched out by a factor of pi (3.14159). So, if you wrap it around the pipeline, you will not see the “circumference”. You will see its diameter. You don’t need to divide your answer by 3.14159.

This Weird Diameter Tape Measure Can Make Your Life Easier

You may be part of a special group of people. We can call this group, FDTU, for “future diameter tape users”. To be in that group, you would have these three qualifications:

  1. You never heard of a Diameter tape measure.
  2. After you get one, and learn how to use it, you will use one every week for the rest of your life.
  3. You won’t believe how you ever got along without one.

To help you on this fun journey as a FDTU, let’s find out…

  • What is a diameter tape.

    It is a measuring tape that, when you wrap it around the circumference of a round object (pipeline or tree), it reads the “diameter”. If you would use a regular tape measure, you would have to divide by pi (3.14159) to get the diameter.

  • How to use a diameter tape.

    How To Measure the Diameter of a PipeYou simply wrap it around a pipe or shaft, or tree, and have the diameter scale face outward, so you can read it. Make sure you don’t use the other side, because it would give you the circumference. 

  • What you will use it on from now on, to make your life easier.

    If you need to replace a car heater hose, but you want to have the new hose on-hand before you remove the old hose, use your diameter tape to measure the diameter (and length) of the old hose. You can do the same routine when replacing plumbing.

My friend owns a marina. He never heard of a diameter tape. I gave him a diameter tape and told him what it was for. He was in the FDTU group, and now he uses this valuable diameter tape measure every day.

Are you in the FDTU Group? Now you know how a simple tape can make your life easier.

 

5 Pipe Diameter Tape Measure Tips

When you use your Lufkin or Pi-Cobra pipe diameter tape measure, here are 5 tips to keep you out of trouble.

How to Measure the Diameter of a Pipe
How to Measure the Diameter of a Pipe
  1. Make sure the pipe is free of dirt and mud. You don’t want to measure those things, just the pipe.
  2. Use the right tape. Do you want your answer in 100ths of an inch, 64ths of an inch, or millimeters? There is a tape for each purpose.
  3. Use the right side of the tape. The other side is probably a regular linear tape. It will give you the circumference, not the diameter.
  4. Wrap the tape around the pipe straight, not at an angle. If it is not straight, you will get an elevated result. You can test this by wiggling the tape so that it gives you the lowest reading.
  5. Be familiar with the scale. It can be tricky on a 64ths of an inch diameter tape. 48 on the scale means 3/4 ” diameter. The easy one is 32, which is of course 1/2″ diameter.

2 Tally Books That An Oil Company Can’t Operate Without

Oil companies are always busy. The drillers need to keep track of the amount of pipe they are putting down the hole. The well operators need to keep track of yield, and what the gauges say. The supervisors need to keep track of employees, and their work hours.

These 2 Tally Books are vital to the oil industry. They are weather-proof, and can fit into your shirt pocket or pants pocket.

The flexible book 3308 is great for a back pocket. It bends when you do.

Both of these books are vital to the oil industry, and help to make it run smoothly.

3 Tricks With A Pipe Diameter Tape Measure

Here are 3 tricks that will make you a user:

Want To Know The Diameter of Your Arm?

  1. Wrap a diameter tape around a car heater hose that you intend to replace. Read the diameter, and the length. Go buy the correct hose, because you know the exact size. Remove your old leaky hose and immediately replace it with the new one. There’s no need to take the old hose to the parts store and leave your vehicle without a hose for a while.
  2. Use the tape to find the diameter of a copper water pipe in your basement that is leaking a little.  Go get the pipe, and have it ready to install when you remove the old pipe.
  3. Need a new rope for your boat? Get one that is the same size as your old one, by measuring the diameter with your “OD tape”.

 

3 Ways You Can Use A Pipe Diameter Tape Measure To Save The Day

  1. Measure the diameter of a leaky heater hose on your car without taking it off and

    letting it drip. Then get a new hose the correct size. Take off the old hose, and immediately install the new one.

  2. When making changes to the copper pipe in your house, measure the outside diameter of the existing pipe, so you can buy the right size. Then you will have all the right sizes when you shut off your water, and start working. You won’t be interrupted by a hasty trip to the store.
  3. Does your boat need a new hose, and you don’t want to remove the old one until you have the right size replacement beside you? Just measure the outside diameter (OD) of the old one, and match it to the new one.

A pipe diameter tape measure is quick and easy to use. If you ever need to do any repair work like this, you definitely need an OD tape (diameter tape).
