通径规Drift Diameter Gauge
通径规是检测套管、油管及其它管子内径的工具。它分为套管通径规和油管通径规。用它可以检查各种管子的内通径是否符合标准，检查其变形后所能通过的***大几何尺寸，是修井作业检测必不可少的工具。
Overview:
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 .
Features:
Drift Diameter Gauges are simple in structure, safe and reliable in use, high-efficiency performance, convenience operation.
