Description

Technical field:

[0001] The invention relates to a calibration device, in particular to a device for precision calibration of various individual instruments involved in the petroleum industry. Background technique:

[0002] Petroleum drilling is a high-cost industry. The drill pipe, casing and oil pipe widely used in its equipment are all made of a special threaded pipe about 10 meters long, and they are basically connected by threads. The thread pitch diameter, taper, pitch, tooth profile angle, tooth height and other parameters of the above-mentioned threads must meet the specified processing accuracy, otherwise the connection quality and service life will be affected in a complex use environment, and production accidents will occur in severe cases. In order to accurately measure various parameters of the pipe thread, a variety of one-way meters are designed to measure a single parameter. At present, there are many manufacturers of one-way meters, such as Hanzhong Wanmu In...
