Drift gauge is a simple and popular tool for drifting inside diameter of casing, tubing, drill pipe and other pipes.
Drift is used to check whether ID of pipes are complied with API standard or not, and to determine the max. inside diameter to be drifted after deformation. The drift is thus granted as a necessary tool in workover operation. The material of drifts is steel or nylon.
There are several types of drifts as structure: one bail; double bails and sub type
