Teflon Drift gauge for tubing Nylon Drifts for casing
Teflon Drift gauge is made by telfon pipe,it is a one-to-one tool used to detect the diameter of downhole tube. It is mainly used to detect whether the diameter of inner holes such as casing, tubing and drill pipe meet the standard. It is a common detection tool for downhole operation, which can be divided into two categories: casing teflon drift and tubing teflon drift and drill pipe teflon drift
