A circumference gauge, also known as a pi tape, is a measuring tool used to determine the circumference of circular objects such as pipes, cylinders, and drums. It consists of a flexible tape, often made of steel, that is marked with measurements in both inches and millimeters. To use a pi tape, the tape is wrapped around the object to be measured and the measurement is read directly off the tape. The tape is designed to conform to the shape of the object being measured, allowing for accurate readings even on irregularly shaped objects.

Kristeel brand Pi tapes offered by Apex Commercial Corporation are commonly used in industries such as construction, manufacturing, and engineering where precise measurements of circular objects are necessary. They are available in a range of sizes and materials to suit different applications. Some pi tapes also feature a locking mechanism to hold the tape in place once the measurement has been taken.

Overall, Kristeel Pi tape offered by Apex Commercial Corporation is a simple yet effective tool for measuring the circumference of circular objects and is an essential part of any toolkit where precision measurements are required.
