Abstract

The invention discloses a portable petroleum pipe internal thread taper measuring instrument, and belongs to the field of petroleum. The portable petroleum pipe internal thread taper measuring instrument comprises a main frame, a sliding rod, a locking screw, a measuring jaw, a displacement sensor, a measuring head and a digital display box, wherein the main frame, the sliding rod, the measuring jaw and the ball center of the measuring head are positioned on the same plane. Petroleum pipe internal thread taper can be measured once by the portable petroleum pipe internal thread taper measuring instrument and can be directly displayed by a digital display, a measurer can directly judge whether the internal thread taper meets requirements or not according to displayed data, so that the measuring instrument solves the problems that the internal thread taper measuring process is complicated, thread alternating is easily caused, an inspector needs to have rich inspection experience and the like on the premise of sufficiently ensuring petroleum pipe internal thread taper measuring accuracy, petroleum pipe internal thread taper inspection efficiency is greatly improved, inspection cost is effectively reduced, and inspection is facilitated.

Description

technical field [0001] The invention relates to the petroleum field, in particular to a portable oil pipe internal thread taper measuring instrument, which is a special measuring tool for the oil pipe internal thread taper. Background technique [0002] The oil pipe thread is a thread with a certain taper, and its taper is defined as the increase in the pitch diameter of the thread per unit length, usually referring to the increase in the length of one inch. The taper is divided into taper 1:16, 1:12, 1:6 or 1:4 according to the standard requirements. In order to ensure the safety of oil pipes during the drilling and production process, there are clear testing requirements for various parameters of oil pipe threads in various standards and specifications to ensure the processing dimensional accuracy and interchangeability of oil casing connecting threads. Improve the safety and reliability of oil pipe threaded connection. [0003] The taper is a very important parameter to...
