What is pipe drift?

Pipe drift refers to the internal diameter of a pipe after it has been manufactured. It is the measurement of the largest possible object that can pass through the pipe without getting stuck or causing damage. Pipe drift is usually larger than the nominal diameter of the pipe, which is the size designated by the manufacturer. This is because the manufacturing process can cause variations in the diameter of the pipe and the thickness of its walls. It is important to measure pipe drift to ensure that pipes are suitable for specific applications, and to ensure that the proper tools can be used for installation. A pipe with a smaller drift than required may cause flow restrictions, while a pipe with a larger drift may be too loose for a proper fit. Pipe drift is typically measured using a gauge or tool that is inserted into the pipe, and it is often expressed as a percentage of the nominal diameter.
