Simulation research on measurement method of geometric parameters of non-contact pipe thread

Abstract

In order to ensure that the pipe thread exerts its good sealing and transmission performance in the oil and gas pipeline, it is essential to judge the geometric parameters of the pipe thread. The experiment uses the 60° standard sealed pipe thread of model NPT1/2 as the research target, the machine vision technology is used to make non-contact measurement of the pipe thread geometry, LABVIEW is used as the software development platform to analyse the processed thread image. Finally, the parameters such as pitch, thread angle, taper, and thread height are simulated and measured to obtain the qualification conclusion.
