When you use your Lufkin or Pi-Cobra pipe diameter tape measure, here are 5 tips to keep you out of trouble.
- Make sure the pipe is free of dirt and mud. You don’t want to measure those things, just the pipe.
- 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.
- 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.
- 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.
- 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.
