This forgotten child gives you the outside diameter of a pipeline in both inches
and centimeters. It is valuable to both Americans (using the inch system) and those who use the Metric system of measurements. It goes up to 38″ diameter (955 millimeters diameter). The only thing it doesn’t offer is the ability to measure straight objects. You would have to have a regular tape for that.
Who would use this tape? Inspectors who travel and deal with both systems. Any drilling companies that use both metric and imperial systems of measurement.
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.
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.

If you need to know the outside diameter of a pipeline, and don’t have an exposed end, this is how you do it. Please click here for a short 2 minute video on this easy task. Let the Lufkin diameter tape do the work for you. There’s no need to use a bulky caliper or micrometer. There is also no need to divide the circumference by pi. A simple pocket-sized diameter tape is all you need. Here is How to measure the diameter of a pipe.
Diameter tape measures are able to give you the diameter of a pipe, pipeline, log, or any other round object. They do it in 1 easy step. All you do is wrap the pipe diameter measuring tape around the pipe and read off the diameter. A regular tape measure would give you the circumference. Then you would have to divide by pi (3.14159). That adds another step, plus you would need a calculator, pencil, and paper to arrive at the diameter.
Do you need to find the diameter of a pipe or pipeline, and you don’t want to have to divide by pi? Of course, you can do it that way–Measure the circumference and divide by pi. But a more accurate way is to use a pipe diameter tape measure.
Other ways: Use a micrometer that is big enough to do the job. Or use a caliper, then transfer the size to a rule, then divide by pi.
Diameter tapes make the job easy, by doing all the work for you on an oil, gas, or water pipe, or anything round, like a tree or telephone pole.
People who don’t know they need a pipe diameter tape measure yet:
Boat repair professionals
Car repair people
I have given Lufkin diameter tapes to these 3 groups of people, and told them how to use it. It only take a minute to show them. They are in awe of the tape, and wonder why they never heard of them. My boat repair man broke his, and wanted to buy a replacement tape. That’s how handy these pocket tapes are. They even can be personalized with your corporate logo in full color.
