Description
Casing and Tubing Drifts are used for testing the roundness of Tubing and Casing; verifying there are no dents, bends or flat areas that would prevent downhole tooling from passing through.
Drifting means measuring a pipe’s inner roundness. Drifting is typically performed by passing a cylindrical mandrel (Drift) through the length of the pipe to detect occlusions.
Our Drift mandrels are manufactured to API 5CT Specifications or, if the requirement is non-standard, we will make to our customers own specification.
Drifts are available in Steel, Aluminium, Teflon and Nylon in size ranging from 2-3/8”-20”.
