It finds the circumference of a round (or oval) object.
A Pipe diameter tape measure is an oil and gas pipeline man’s best friend. Those who drill oil and gas wells find a diameter tape a necessity. It retracts and fits in your pocket. It’s ready to use all the time. No calculations or calibrations are necessary. All you do is wrap it around the pipe and read the diameter off the diameter scale.
If you need the circumference of the pipe, just wrap it around the pipe and read off the circumference scale.
I always enjoy explaining how to measure the diameter of a pipe. Doing the measuring actually takes less time than explaining it. It’s easy, too, because the pipe diameter tape does all the work for you. It takes about 10 seconds to do this little task. All you do is wrap the od tape (diameter tape) around the pipe or pipeline, and read off the diameter directly from the tape. The video found here in the header picture pretty much shows you how simple it is.
This is a valuable tool for people in the oil and gas drilling business, automotive repair, boat repair, tree people, arborists, tree nurserymen, landscapers, and anyone who needs to know the diameter of a round object. This allows you to find the diameter without cutting it and measuring the diameter directly.
If you are in the oil business, or drilling, or plumbing business, you are always measuring pipes. You also need to know the outside diameter of pipelines and pipe fittings that are part of a piping system. How do you do that without cutting the pipeline and measuring the diameter directly?
Use a caliper, and transfer the measurement to a metal rule. This works, but is only as accurate as the metal rule, and your ability to transfer the distance to the rule. Also, who wants to carry around a caliper all day?
Use an OD micrometer. But what size micrometer do you need? A 0-1 mic will only measure a pipe that is less than 1 inch in diameter. A 1-2 mic will only measure a pipe that is between 1 and 2 inches in diameter. Who want to keep a whole set of mics with them in the field?
Use a flexible measuring tape, wrap it around the pipeline, make a reading and divide by pi. This works, but it’s not that accurate because the markings are on the side of the tape that is not physically next to the pipe. Your are really measuring the diameter of the pipe plus twice the thickness of the tape.
Are you in the gas and oil business? Or any business that needs to keep continual records of data in the field. The best and safest way to make regular notations of gauge readings and pipe usage, is with a tally book. Oilfield tally books are small, weather-proof pocket sized notebooks that are protected by vinyl covers.
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.
