Drift diameter gauges

The Drift diameter gauges are simple and general tool designed to measure inside drift size of casing, tubing,drill pipe and other pipes. In order to live up to the standard requested, it used to inspect the inside drift size of a variety of tubings. The biggest size will be known through inspecting after deformation. It is the essential tool in the course of workover .

 

Construction and technical standard

The Drift diameter gauges are made of drift board and connecting rod.

First, the specification of the drift must adapt to the I.D of the casing respected.

Second, the periphery of the drift can not have scars and other adhesive content.

Finally, the O.D of the drift should be inspected after working each time, if the abrasion of the O.D is more than 0.2mm, the drift can not continue to use.
